Description

The present invention relates to an optical pickup for CD / DVD / BD / EBD, an optical head for diagnosing / removing a local fine lesion, a stereoscopic display / imaging apparatus, and a printer / scanner.

Optical discs, which began with the replacement of music records in the 20th century, have been established exclusively as computer peripherals in pursuit of shorter wavelengths. Optical discs will survive as one of the main media without being replaced by semiconductor memory. However, in the 21st century, I think that the direction will change to an optical disc of a different shape.

This paper consists of an optical system consisting of LD, PD, and lens established with CD, or the optical system of an optical disk as a ground solution with a unified wavelength of DVD / BD. Describes and describes the ultimate solution, Heavenly Solution. Tenjou is a technology renovation group in which the physical principles are reviewed and the maintenance of the global environment is implemented as the ultimate solution, and is carried out while all the science and technology of human society undergo an innovative transformation. The ground solution has duplication and competition between companies, and there are repetition and destruction of old formats, but the top solution is given the ultimate solution from the beginning and does not depend on the technology evolution. Heavenly solution is something that someone on the earth will end up in what the creator has prepared from the beginning. Heavenly solution is not an extension of ground solution, and there is no technical connection. In many product technology fields, the future is invisible. Heavenly solution comes from the future now. What was missing from anyone in the optical disk that should have been compiled as a ground solution during the 20th century

1) Decision to not pursue wavelengths below 400nm that cause problems such as transmittance in optical components 2) Able to read and write 25GB BD and 40GB EBD (Enhanced-BD) 3) Easy to manufacture OP and cost 2 / 3, and 1.5 times longer life at the same time 4) Overcoming the protective layer thickness problem of 1.2mm / 0.6mm / 0.1mm of 3WayOP 5) Thinner OP, lower power, Show a clear milestone for speedup 6) Be a stepping stone to a smooth and dynamic transition from 2012 to the sky

The purpose of the culmination is to reconstruct the format created so far in a physically unified form as shown in FIG.

The application of EBD shown in FIG. 1 is a resolution of 1920 × 1080 HiVision-DTV, which is not sufficiently fine, MPEG2 / 4, H.264. H.264 image compression and 2-hour planar image information recording with BD corresponding to it, allowance for improvement in image details, and correspond to an intrinsic stereoscopic image display device for which a solution has already been found as a top solution, The recording capacity is 1.6 times that of BD for inserting and recording the differential image compression signal between the eye imaging information and the left eye imaging information. This is also integrated with the 3D-GUI implementation of the PC platform. The 3D-GUI is for performing a GUI with a three-dimensional handle by placing a hand in the stereoscopic display space, and remarkably improves the operability of the PC instead of being realistic.

In order to maintain the compatibility of the optical disk player, it is necessary to maintain the switching of the protective surface layer thickness 1.2 mm / 0.6 mm / 0.1 mm for determining astigmatism and the compatibility of the lens NA. Fig. 2 compares the conventional idea with the one in this paper. Conventionally, it has been the idea that a high-density recording performance of X-Disc can be obtained if a different wavelength LD is used for each of three-way recording / reproduction of CD / DVD / BD so far and if a short wavelength light source of about 350 nm is found. It was. However, since there is already an optical solution for optical discs, and the physical principles of all things have been elucidated in a different way, what is necessary for the ground solution of optical discs is the consumption of 20th century R & D and product introduction. It is to break the vicious circle and measure the culmination including the future to touch the sky. The culmination of 20th-century optical disks solves the problem of switching between 405 nm (BD) and 650 nm (DVD / CD) to cope with the pit height, a single lens with NA = 0.85, and the protective layer thickness of DVD / CD In addition, an optical system called a one-system or two-system LD / PD array is used to cover the space between CD-EBDs with an OP composed of several parts.

As Richard Feynman revealed, plastic has a refractive index, and the refractive index has some dispersion (wavelength dependence) because the medium has a frequency resonance point of molecular structure as shown in Equation 1, and then This is because re-radiation due to vibration at the base becomes a phenomenon of refraction at a distant wavelength. The medium is opaque at frequencies higher than the resonance point of this molecular structure. Even if it is lower than the resonance point, the permeability is lowered. Without knowing the basic facts already known in the 20th century, including the actual light emission mechanism of LD, the pursuit of shortening the wavelength to the people has resulted in confusion for consumers and global consumers. , Make researchers live an unsatisfactory life.

<The 20th century science fallen child>
Typical examples of conventional Philips = Sony type CD / DVD / BD 3 Way OP are the Philips type and the Sony type. Both are orthodox configurations, but in the Philips type, the LD is divided into three by the optical path, and the 3-way PD is placed in the same place. The Sony type has a three-wavelength LD at one location, and the PD is divided into three LDs by an optical path. On the other hand, the new 3.5-way PD array does not necessarily require alignment of the mirror image relationship between the LD and the PD.

FIG. 3 shows the Philips type, and FIG. 4 shows the Sony type.

In a tangible manner, the conventional method is a device in which an experimental apparatus is brought into a product as it is, and can be called a classic form. In order to be able to design products freely without experimentation, the optical principle must be understood by a truly correct theory, and an optical system must be designed with 2% accuracy by computer simulation alone. In the past, not only did the academic and industrialization systems for that purpose not be sufficient, but also made many essential mistakes. Even so, the product was a result of the efforts of engineers.

<Verification of operating state of BD>
BD has forced HD-DVD to stop, but it's a storm in the cup, and this competition contains nothing essential. The opponent who must compete and confront is natural law. In order for the 20th century type optical discs to be compiled in the 21st century, the physical principles need to be correctly understood, and the basic architecture of the OP needs to be rearranged and reconstructed from the ground up. If you organize the classical form

1) Recording / reproduction with an LD as a point light source 2) Detecting reflected light re-condensed through the objective lens with a quadrant PD 3) Using a half mirror to mirror the center of the quadrant PD and the light emission point of the LD 4) Use with NA limit and no side lobe 5) Use multi-value recording if possible, and use super-resolution when recording

This paper will show at the same time that the implicit rules of these goals and principles that were considered absolutely correct are not necessarily correct.

FIG. 5 shows the conventional OP structure of a BD. The use of a collimator lens to collimate the optical path is not essential. One essential thing is that the directivity of radiation becomes an ellipse due to the structure of the edge-emitting LD. In order to reduce the beam spot diameter converged by the objective lens, it is effective to increase the NA value equivalently by allowing spillover and making the irradiation of the lens portion close to a uniform distribution. If the radiation angle from the LD is constant, the optical path length between the LD and the objective lens is inevitably increased, and the finite emission point size of the LD is reduced as an a / b spot image. This is the B position. The A position is the opposite, with almost no spillover.

FIG. 6 shows a simulation result of the radiation distribution in a specific WxHxL of the edge emitting LD. It reflects an understanding of the operation of the LD and, of course, matches very well with the real thing. In general, the full radiation angle in the vertical direction is about 40 degrees wide, and the horizontal direction is about 20 degrees wide. It can be seen that the radiation distribution can be approximated not by the raised cosine distribution but by the cosine distribution (dotted line portion in the figure) shown in Equation 21. The double circles in the figure indicate the size of the objective lens that should irradiate the LD radiation distribution in the A and B positions.
FIG. 7 shows a spot shape when the radiation distribution of this LD is irradiated (illuminated) on an objective lens with NA = 0.85 as the body position A. The scale on the horizontal axis is in wavelength units. This is like the relationship between the time axis and the frequency axis of Fourier transform, where the pulse width on the time axis becomes narrower if the frequency bandwidth is wide. Normally, the track direction corresponds to the width of the active layer of the LD, and the pit row direction corresponds to the thickness of the active layer, giving priority to the resolution in the pit row direction. If the thickness is small, the radiation angle is widened and the effective NA is increased, so the spot diameter is reduced. As NA increases, the third lobe response increases. However, if the intersymbol interference is in the same pit row, error correction is performed in PRML, but equalization is not performed. The spot diameter of this BD is derived from Equation 3.
FIG. 8 shows a spot shape when the radiation distribution of this LD is irradiated to the objective lens with NA = 0.85 as the body position B. It can be seen that the beam is thinner and the side lobe is larger than in the A position. In the B position, a part of the amount of irradiation light is discarded by spillover. Most BD players on the market are mainly designed with a wide beam A position and have no spillover concept. If you throw it away, you will not stand up. Formula 4 corresponds to spot formation of the B position of the BD. Formula 4 is a derivation formula for the spot shape of the B body position.
Although the effect of the size WxHxL of the LD active layer on the spot shape has not been treated so far, the answer cannot be obtained unless the head is slightly twisted. This problem must be considered in three parts: WxHxL / n, ΔWxΔHxΔL, and astigmatism. n is the refractive index of the active layer. ΔWxΔHxΔL is the phase dispersion due to the electromagnetic field distribution of the active layer which is a cube. Since the astigmatism of LD is required to cancel out the astigmatism of the thickness of the protective layer of the disk, it is meaningless to take it alone. The size of the object WxHxL can be regarded as a point light source as shown in FIG. 10 if the phase of light emission in the active layer is aligned, but it actually contributes to increasing the spot size. . The change of the spot shape by WxH which does not consider the length L of FIG. 9 is shown. The spot diameter becomes astigmatism and the side lobe is slightly relaxed. Equation 5 is an equation for deriving it.

FIG. 10 shows the reason why the light emission in which the phases of the active layers of WxHxL are aligned can be seen as a point light source. In FIG. 10, since the phase of the light emitted from the frontmost part of the active layer and the light emitted from the deepest part are opposite to each other across the phase of the light emitted from the equivalent light emitting point, the vectors P1 and P2 are The added phase is equal to the phase of P0, and the amplitude is already reflected in the radiation distribution of FIG. 6 as a vector sum. That is, as the characteristics of the LD, the width W and height H length L / n contribute to the pit surface by a value obtained by multiplying the phase dispersion ΔWxΔHxΔL by the image magnification b / a.

So why does WxHxL / n itself influence the spot shape? It is smaller than 1 at an aperture coefficient radiation angle θ of WxHxL / n and becomes COS (θ), so that NA is equivalently reduced and the spot diameter is increased. To re-arrange, the inverted image through the objective lens of the active layer of the LED is a three-dimensional image with depth, but the inverted image through the objective lens of the LD active layer has phase dispersion in depth, width and height. It is an image close to a point, shrunk only by the amount of. The main element of ΔL is astigmatism generated due to the refractive index of GaN of 2.5, which can be offset by adjusting the ratio of astigmatism due to the thickness of the protective layer of the disk and a: b. . The sub-element of ΔL is phase dispersion in which the phase of light emission deviates from the speed of light in the medium. An attempt to confine light by providing claddings on the upper and lower sides of the active layer is a mistake because ΔL increases significantly. If the phases are aligned, the light will only travel forward. If a clad is provided, the threshold current that is phase-synchronized from the LED mode to the LD mode can be lowered.

<Properties of LD light source>
So far, the theory of synchrotron radiation when using an LD as a light source has not been established, and the wrong explanation has been passed that a laser is an oscillation. The design based on the calculation of the LD is at most a follow-up analysis of the current distribution in the active layer, and the understanding of the mechanism of light emission has not progressed, and has been developed exclusively through trial and error through experiments. In addition, there was a delay in the process between the confirmation of light emission by the LED with a new material and the commercialization of the LD, even if the confirmation of reliability was excluded. However, for some reason, only the belief that LED can always become LD sometime has grown as a rule of thumb in the industry. It is a natural story. Because it is not an oscillation phenomenon, the problem was whether the crystal structure could be maintained when the current was increased.

In this discussion, the true theory of LD is suddenly established, the optical system can simply calculate with sufficient accuracy, and the confirmation of short wavelength LED emission and the transition to the LD mode will proceed simultaneously as product development. FIG. 11 shows the basic concept of LD.

There has been a large misconception about the operation of LD. In the active light emitting layer, the standing wave reflected by the mirror surfaces (dissolved surfaces) at both ends rises, and the operating principle of the LD is that stimulated emission is caused by the electric field. The understanding of stimulated emission, which Einstein explained, is a bit suspicious and sounds like something special, but that is the beginning of the mistake. When the diode is regarded as an electric circuit, a current obtained by adding the applied voltage to the Boltzmann temperature distribution voltage of kT / q volts exceeds the band gap voltage of the transition of orbital electrons. This current increases exponentially with increasing applied voltage. In LD, the applied voltage plus the electric field of reciprocating light simply exceeds the band gap voltage, and it is natural to synchronize the phase. FIG. 12 shows the mechanism of the LD.

Einstein's interpretation was correct only in response to the Brownian motion and the EPR paradox against Heisenberg, but the latter was the seed that led to the quantum theory of the photoelectric effect that he struck himself. NL obtained by multiplying the length L of the active layer by the refractive index n is the optical path length, and the round-trip optical path length is an integral multiple of the emission wavelength. When this integer changes, the light emission becomes unstable. Or it operates with a plurality of integers, and a plurality of corresponding wavelengths appear.

Light as electromagnetic waves is repeatedly reflected by the mirror surfaces at both ends. As shown in FIG. 13, the standing wave is a combination of two traveling waves. If the active layer and the upper and lower layers have the same refractive index, the structural analysis is simplified.

Of the two traveling waves, as shown in FIG. 14, the return light does not contribute to the radiation to the front surface. This is because there is no synthesis in the light emission phase of each atom, and the sum can be treated as zero. You can't see anything moving away at the speed of light. On the other hand, in the forward light, the excitation chain due to the wave progression occurs at the same speed as the wave velocity of the medium, so that the phase synthesis is integrated in the same phase. The active layer can be regarded as a cubic phase and array radiator.

That is, as shown in FIG. 15, the emission pattern of the LD is uniformly distributed (in this case, for simplicity of calculation) in the HxWxL cube, and the phase of the emission is from the back to the front. It is a radiation antenna in the order of the speed of light in the medium. The up / down / left / right directivity half-value angles become n times when going out of the medium. The directivity is shown in Equation 6, Equation 7, and Equation 8. The radial distribution of the stereoscopic display is expressed by Equation 6, the radial distribution on the X axis is expressed by Equation 7, and the radial distribution on the Y axis is expressed by Equation 8.
FIG. 16 shows a radiation pattern.

It is from H <W that the radiation directivity of a normal LD becomes a vertically long ellipse. Once the LED material is completed in this way, LD mode light emission and its radiation pattern formation can be freely made in the future, so it is no longer the subject of discussion. The reliability of the LD means that the electromagnetic field of the reciprocating light exceeds the band gap of the crystal lattice and the crystal is broken (the dark line is one side thereof). Astigmatism of the protective layer of the optical disc, which causes astigmatism due to refraction when the emitted light goes out of the medium, is canceled out.

The radiation directivity angle of the LD is mainly inversely proportional to the height and width of the active layer and does not depend much on the length of the active layer. FIG. 17 compares H = 3 wavelengths, W = 10 wavelengths, L = 20 wavelengths, and L = 80 wavelengths.

Formula 9 is the calculation formula.
If the refractive index of the LD chip is n, the full-width directivity half-width inside the chip goes out of the chip, and the sine of the half-angle becomes a full-width directivity half-width of n times. On the other hand, if L is not long, the directivity half-value angle is inversely proportional to W and H. Within the chip, the wavelength is shortened to 1 / n. From this, the full width at half maximum of the directivity of W and H due to the shortened wavelength as viewed from the outside of the chip coincides with the directivity half angle at which the refractive index of the medium actually exists and radiated to the outside. This paper clarifies mathematically the relationship between the radiation pattern of LD and the active layer for the first time. As a result, the LD can be designed accurately. Even if the light emission is emitted from a laser diode in a fan shape or parallel light rays, there is no inherent difference in ability to become a point on the pit surface. However, since the narrow parallel beam uses the center of the lens, the effective NA becomes extremely small, and the spot intended for the point light source becomes a huge circle. Fan-shaped radiation is indispensable. The light emission distribution of the active layer is not actually uniform, but the calculation of the three-dimensional distribution is very simple. Since the specific design of the LD is not the subject here, the details are omitted.

In LD, increasing L has no meaning other than not increasing the wavelength accuracy and current density, and is determined only by the length that can be solved and the yield from the wafer. Even if L is long, the deviation from the point light source is not substantially added in the medium unless a cladding layer is added. In general, a point light source can be said to be a point when an image is made through an objective lens if the phase of the wave front is aligned with parallel rays. It can be said that there is much phase dispersion in the plane. The depth of the emission center viewed from the outside is a value obtained by dividing half the length of the active layer by the refractive index. Most of the size of the LD point light source is astigmatism when it goes out of the medium. As described above, the ratio of the value obtained by multiplying the thickness of the protective layer of the disk by 1.5 of the refractive index of polycarbonate and the value of multiplying the half of the LD length L by the refractive index of the medium is the ratio of a: b. If they are equal, astigmatism cancels out on both sides of the objective lens.

All LD design engineers now believe that there is no radiation behind the active layer, but there is radiation in the vertical direction, which must be confined by the cladding. But it is clearly wrong. Although it can be easily understood by calculation, the cubic radiation array of the active layer does not radiate in the vertical direction. This is because all the LD design engineers still believe in the mistake of energy radiation that Oliver Snakeside committed hundreds of years ago. Recently, it became free from Oliver Snakeside's lies, whether or not they were aware that they were able to transmit and receive wireless power at an efficiency of more than 80% at a location 6m away at a university in the eastern United States. People. FIG. 18 shows the movement of the emission center as viewed from the outside of the LD.

The astigmatism amount coming from L due to the refractive index of the active layer of the LD, the astigmatism amount due to phase dispersion in the opening of the WxH, and the astigmatism amount of oblique transmission of the half mirror are added to the objective lens. If the amount of astigmatism due to the thickness of the protective layer of the disk on the side is equal, they cancel each other out, so the amount of correction of astigmatism by the objective lens is zero (astigmatism neutral). When a / b is increased, astigmatism is small and appears on the pit surface, but spillover without irradiating the objective lens increases. In order to avoid this, when the active layer of the LD is lengthened as shown in FIG. 16, the radiation angle becomes small. Changing W and H is meaningless because it cancels out the irradiation angle, that is, a. The relationship is shown in FIG. The oscillation of the LD will be described later.

<Return light and multi-wavelength mode>
Observing the operation of a single LD and examining the monochromaticity and radiation angle is not very meaningful. Hypothetical physics of the 20th century gave allegorical implications and hopes of fancy to lasers. LD and LED are the same. Disturbance caused by the return light measured by the LD alone can be eliminated by appropriate handling in an actual system. Similarly, the multi-wavelength mode has no problem. The following is extremely important for optical disc recording / reproduction.

Stimulated emission due to the electromagnetic field in the return path where the return light from the disk surface enters from the end surface of the LD and reaches the back surface does not contribute to the radiation to the front surface at all. Only stimulated emission due to the electromagnetic field in the forward path contributes to the emission to the front. If an image is formed on a spot having a NA limit size on the pit surface, with respect to the reflection of the mirror surface portion, resonance occurs at an integral multiple of the wavelength between the pit mirror surface portion and the back surface of the LD. Since this is a laser resonance with a long optical path, the monochromaticity is extremely high. The transmittance of the end face of the LD is the only thing that inserts water into this intrinsic-beatiness. When the OP is operating normally, the transmittance of this end face is preferably 100%, but what has been actually designed is that the transmittance of 1% is given, and the reality is that the LD is statically looked at and euphoric. It is.

Originally, all molecules in the active layer of the LD must face each molecule in the phase change recording layer on a one-to-one basis. If the number of active layer molecules multiplied by the bandgap voltage of the bond is not sufficiently stronger than the product of the number of molecules in the recording layer multiplied by the bandgap voltage of the phase change, it will be killed before the phase change occurs. It becomes a dark line. Contrary to this creator's providence, the transmittance of the LD end face must not be 1%. The active layer must contribute to the entire OP. The resonance length of the top emission LD is short on the surface, and the resonance is performed in the entire OP. The fact that an OP cannot be constructed if the condition that is an integral multiple of the wavelength of the entire OP is not satisfied is a major principle that must be consistently observed from the beginning of CD development. Otherwise, no spots are formed. The LD end face is exactly the wall of sectionism.

The principle of an integral multiple of this wavelength remains the same not only for the mirror part but also for the return light from the pit part. Both the multi-wavelength mode and the return light disturbance are not undesirable and are indispensable. The Creator does not make anything unnecessary. There is no unrewarded effort, no meaning, no contribution. That is the origin of the universe and society. From the viewpoint of speeding up, the distance from the back surface of the LD to the pit surface of the disc must be shortened. Since CSOP weighs about 2.5 mg, the operating distance can be made sufficiently small to accommodate changes.

<Coherent nature>
It seems that there are no people in the world who can not only correctly understand coherency but also define it correctly. Even if the coherence is misunderstood, the optical disc can be designed but not applied. Therefore, a uniform shape is completed and far from optimization. If you correctly understand that coherence is a meaningless expression, the engineer can open up a new world. If you look at the academic and industrial world, there seem to be five perspectives on the term coherency that exists for laser light.

1) High interference 2) A thin parallel beam can be maintained far away 3) A single spot can be focused 4) Large energy 5) Phases are aligned

Those who are in the world of optics fully understand that light and electromagnetic waves are a single thing. No one is aware that it has particle properties with respect to electromagnetic waves. There is no one who doubts that the light has particle properties. The people strangely use light and electromagnetic waves and become double standards. There is no person who understands the above 1) to 5) as the mechanism of light with the same mechanism that radio waves have achieved. In other words, something is believed in the subject and I have no insight to dispute it.

Let's clarify each of these vaguely understood and misunderstood. First is coherence of coherent light. This is clearly wrong. Natural light has various phases, and laser light has the same phase. Independently of that fact, interference occurs to the same extent. The interference of double slits is completely different between laser light and natural monochromatic light. Everyone understands that there is no difference between oil film interference and anti-reflective coating between laser light and natural monochromatic light. However, coherent light is believed to be highly coherent, and at that point it first completely loses its logic.

They understand without exception that coherency has spatial coherency and temporal coherency, but no one can give a concrete example of the difference between spatial coherency and temporal coherency. Radio waves can usually observe vibration as a waveform, but light does not have such a detector and can only know the light intensity resulting from the interference. Radio waves are usually used in a phase-matched form, but professors are expected to expect that the phase-matching must be something that has to be done using the intensity and polarization plane for light. Has been trained by and has also been forced into the industry.

No interference occurs even if natural light or laser light of the same wavelength comes from the opposite direction and crosses. A standing wave can only be defined near it. However, natural light and laser light usually come from the same direction and interfere. If the direction of arrival is slightly different, the interference is limited to a certain length. Old and young opticalists who learned the term coherency gave it the term spatial coherency. What the optician who first created the word coherency thought, however, is quite different from the following opticians. It only defended Heisenberg's feeling that the photon is there as an established existence.

To be precise, if the measurement wavelength of a 650 nm LED is 50 nm wide, the wave packet is 650 × 650/50 / Pi long and the orbital transition is completed in four rounds around the electron nucleus. It corresponds to. The wave packet for about 4 cycles has its length spread in the radial direction. However, in the azimuth direction, the stone ripples thrown on the surface of the water diffuse so that it spreads, so it is meaningless to say a finite spread. The same applies to LD light. In other words, spatial coherency is a term that is emptied as many times as stated. If the emitted light from the LED / LD hits the objective lens 20 mm away, it spreads to that extent, and if it hits a huge objective lens 2 m away, it spreads to that extent. There is no need to say spatial coherency.

On the other hand, four cycles of wave packets are radiated from the LD one after another in phase, and it may be considered that each single wave packet break is not visible and is an equivalently large wave packet. . Therefore, it may be considered that it has a spatial extension of its enormous length, but that does not mean that something will be particularly useful. Since the LED light has a wave packet of about 4 cycles, if the pit height is not a quarter wavelength but 10 and a quarter wavelength, there is no interference in the radiation of a single orbital transition. If it is LD light, it will interfere. That said, it is not meaningful because it is not used in such a state. Even if the path length difference that does not interfere with the 4-cycle light of the LED but interferes with the LD is called temporal coherency, it can be used for a laser ruler and has no industrial meaning.

Emission from one orbital transition causes re-emission at the end of the eastern universe and at the same time re-irradiation at the end of the west universe, the two re-emissions meet again and are the same in two 45 degree tilted mirrors If it is directed in the direction, it causes perfect interference. Only the strength is weakened. Also, the interference is only unstable due to the fluctuation of the earth's air (ie, the re-radiation of air). In this system, the story becomes complicated just because of coherency in space and time. This also defends Einstein's EPR paradox, but in the first place he lied with the photoelectric effect, so he became his own paradox and couldn't tell Nilsboor strongly. Photonism does not mean that light has quantum units, but orbital transitions that respond to it are only counted as an integer, whether or not they have transitioned.

Next, the ability to create a narrow parallel beam far away has no direct relationship with coherency. The ability to produce thin parallel rays means that it is a point light source. If it is a point light source, the light radiated | emitted from a wide angle from there will become a parallel ray by a lens. It is the same for both natural light and laser light. There is no relationship between being in phase and being a point light source. 2) and 3) have the same meaning because being able to focus the light beam at one point is the same as being parallel rays. The light emission from one orbital transition is an ideal point light source, but it is weak and does not last long. When many orbital electrons are used, they become stronger and last longer, but they do not become point light sources. The LD lasts strongly and can be treated as a point light source by phase synchronization.

In most cases, having a large amount of energy refers to the amount of light per unit area collected at one point. Although the light emission capacity per unit object is the same between the LED and the LD, the capacity of concentrating the radiation forward is about 100 times larger in the LD. But this has nothing to do with coherency. In terms of the fact that the phases are aligned, the phases of the LD light are approximately 100%, and the LEDs are totally random.

The term coherency originally refers to coherence, not the fact that the phases are aligned. However, the coherence is not related to the fact that the phases are aligned, and there is no difference between natural light and laser light with nearly 100% phase alignment. That is, the term coherency has no logical meaning. Imagine that the concept of coherency is an ambiguous concept that was introduced with the existence probability in mind when Einstein-Heisenberg wave and particle duality is present. Einstein and Heisenberg are in conflict with each other in quantum theory, but it was Einstein itself that explained the photoelectric effect. No one handles radio waves in quantum theory. Therefore, no one will be damaged for the time being if the optics can be handled in the same way as radio waves. As soon as people bring up coherency, they lose quantification. If optics is a radio wave, coherency will soon be forgotten. This is because radio waves do not say coherency. And quantum theory will disappear in a few years. This is because the semiconductor structure, noise process, nuclear fusion, DNA analysis, superconductivity, cosmic structure, and big bang process all do not require quantum theory. When quantum theory is eliminated, academics and industry develop greatly, and the global environment is saved brilliantly. That is the 21st century.

A term that has never helped coherency has been created to defend quantum mechanics, despite the fact that quantum mechanics make no contribution to doing optics. The only thing that is clear is that the laser diode can emit light with the same phase, but it does not make use of the fact that the phases are aligned, but only uses that it can emit strong light. The same applies to laser processing and laser knife. The observation of light from celestial bodies has nothing to do with coherency. An interferometric telescope is one in which orbital electrons of one atom of a distant star give a phase difference to two telescopes on the earth. Since it comes from one atom, there is a 100% correlation. Since the results are irrelevant to the distance between the telescopes, it can be seen that there is no spatial coherency. Interference occurs when light emitted from one atom passes a point through a different path. The light from different atoms also interferes and is reflected by the mirror. The light emitted from one atom is usually a wave packet of several cycles, which is the case with LEDs. When this wave packet is Fourier transformed, the wavelength appears to expand. This is because a spectrum of a different frequency is not emitted due to the presence of noise, but spreads in the frequency domain because the wave packet is short. When an atom is excited by an electromagnetic field with a frequency that matches the orbital transition, the wave packet becomes much longer. It is an error to interpret this as a pumping condition. In the case of an LED, it is a constant short wave packet because it is a DC electric field excitation. The wave packet of light emitted from one atom ranges from several cycles to an infinite length, and it is a mere delusion of Max Planck at the end of the 19th century that it is gathered with a value corresponding to hv. If the LED is DC driven, the number of cycles is close to hv.

<LED / LD noise>
Another important thing is the noise contained in the luminous flux. Although it is important, it is not widely known, but white noise included in the light emission of the LD with the same light amount is 30-60 of LED light or natural light as shown in Equation 10 and Equation 11. Is double.
In the LD, one spontaneous emission causes 1000 to 4000 stimulated emission numbers compared to LEDs and natural light whose emission is completely irregular. That is, since the unit charge acts as a lump of 1000 to 4000, it may be understood that mq is substituted for q. In the stimulated emission, the red signal family follows around the seed and the phases are aligned, so that the noise power is 1000 to 4000 times. This is the same principle that a very large white noise current is included in the DC current of the Zener diode. Photomultipliers have the same large excess noise principle. In the case of LD, LED operation is performed when the direct current is small. The directivity coefficient in the LED mode and the LD mode is 100 because the refractive index of GaN is 2.5 for elliptical radiation of 40 degrees × 20 degrees. The ratio of the increase in the light output to the increase in the current is 100 times different in the LED in the LD. FIG. 20 shows switching from LED to LD.

It is understood by many opticalists that LD noise comes from spontaneous emission. However, contrary to the Creator's providence, there are opticians who fall into self-confidence trying to escape this spontaneous emission noise. Pitiful. In order to know the noise of the LD accurately, it must be based on the mechanism shown in FIG. T of kT / q is an absolute temperature, which means that the nucleus and the orbital electrons around it are excessively oscillating in response to the incoming electromagnetic field. The isolated nuclei and orbital electrons do not have such an incoming electromagnetic field, so there is no excessive vibration and T = 0 degrees K. This is the fundamental definition of temperature. The LD placed at room temperature T = 0 ° K tends to exceed the band gap voltage between the inner shell orbit and the outer shell orbit with a voltage obtained by adding kT / q to the applied Vdc. However, since the definition of T is noise (temperature = noise phenomenon), the flowing current, that is, light emission varies. A current generated by adding the Boltzmann temperature dispersion exceeding the bandgap voltage is called shot noise, and its power is proportional to T, but is completely different from thermal noise. However, since the electric field of various light emission is applied to Vdc, from the viewpoint of noise, the same positive feedback of noise occurs as when kT / q is increased 1000 to 4000 times.

Although there is no change in the internal quantum efficiency in the LED operation or the LD operation, the external quantum efficiency in the forward direction changes abruptly with the threshold as a boundary because the emission of the LD is phase-combined forward by stimulated emission. When the drive current of the diode performing the LD operation is reduced, the LED operation is performed, and the decrease and emission of the current become four directions, so that the irradiation of the pit surface is suddenly reduced. On the other hand, since there is little noise in the LED operation, if m = 2500, the LD is worse than the LED by 15 dB even if the light quantity is 100 times. There is no difference between LED and LD light in the light-dark pattern of interference due to the pit height and the light-dark pattern due to phase change reflectance. It is possible to defocus with the LED and switch to the role of reference light so that the image of the pit comes to the PD surface. In this case, the resolution degradation is obtained by adding the aperture due to the size of the divided PD to the NA limit. On the other hand, in the classical form, deterioration due to the size of the active layer of the LD is added to the NA limit. Both are comparable. Thus, the classical form is not necessarily an advantageous method.

The explanation of the conventional optical / semiconductor engineer stated that a spatial negative resistance was generated in the active layer and this was an oscillation phenomenon due to an inversion distribution with a threshold current as a boundary, but it is a terrible mistake. Specifically, when the round-trip electromagnetic field of light exceeds the band gap, the emission from each light emitting point aligns the phase, but the light emission phase becomes completely irregular below the threshold. It does not oscillate by any means, it is a light emission mechanism with just the same phase. The diode itself does not have a differential negative region as a tunnel diode. The relationship between the current and the total amount of light emission increases monotonously and approaches saturation by heat generation is exactly the same for LEDs and LDs.

Therefore, it is a terminology that the laser is sometimes called a laser oscillator. Neither gas lasers nor semiconductor lasers have an oscillation mechanism. For example, even if a turbulent wave is input to a waveguide or a coaxial cable, it becomes a uniform mode as it propagates. The LD is a light emission mechanism that emits uniform radiation on the same principle. The LD has a point light source property at the expense of noise as compared with the LED. In the LED, the size of the light source is the active layer WxHxL itself, but in the LD, in the phase-locked mode, when viewed from a distance, the size becomes ΔWxΔHxΔL. Regarding the coherence of the LD, there is no difference between the LED light and the LD light so that, for example, the natural light and the LD light receive the same benefits from the non-reflective coating. Interfering with LD light because it is coherent is a complete discovery, and it itself uses the term coherent incorrectly. Moreover, the word coherent cannot be used for any purpose. As a tentative proposal, the term coherent is abolished and paraphrased as laser diode.

The mechanism by which the multispectral mode changes with current is straightforward. This is because the boundary line exceeding the band gap on the outside of the active layer WxH spreads as the current increases as the electromagnetic field reciprocates with the phases substantially aligned by light emission. This is not possible with a concept such as a quantum well, but a three-dimensional analysis cannot be performed. As a result, there is no time difference between the development of the LED light emitting diode and the development of the LD, and it is only necessary to analyze the operation of the LD mode in parallel with the diode development. Disappears.

If the bandwidth of the photocurrent for N-times speed reproduction is 1 GHz, the direct current necessary for the LED to provide C / N of 30 dB for each LED is m = 2500, which is shown in Equation 12. In the case of LED light, Equation 13 is obtained.
Considering the NA and the refractive index of the LED chip, the current required for the LED is 30 uA. If the capacitance of the PD is 2 fF, the impedance at 100 MHz is 800K ohms. The electromotive force generated when a signal current of 0.1 mA / rms flows through this is sufficiently large.

PD can convert 80% or more of incident light, excluding the reflection on the surface, into current. This current flows through the ground capacitance of the PD and is converted into a voltage. Therefore, the signal voltage is inversely proportional to the frequency. At the same time, since the noise current is inversely proportional to the frequency, the C / N at the PD does not depend on the capacitance value of the PD. However, since the noise of the first stage amplifier does not depend on the frequency, it is extremely important to reduce the capacity of the PD. When the response of the photovoltage is made flat with respect to the frequency by negative feedback, the noise of the first-stage amplifier increases in proportion to the frequency, so there is no change in C / N. The conventional quadrant PD has an unnecessarily large area, and is not a good method for noise. The correct design is to place the divided PD in a place where the image magnification is small. FIG. 21 shows a typical example of a PD array and a first stage amplifier. PD is a deep trench made of SiO2 to reduce the side junction capacitance. It must be recognized that the reflection loss on the surface of the PD occurs due to the difference between the refractive index of silicon and the refractive index of air. The depth of penetration into silicon at a wavelength of 405 nm is very short.

The point is mentioned.

<NA limit and sidelobe reduction>
As classic optics says, the resolution is determined by 1 / NA. However, it is common for a lens to irradiate light emitted from an object with a uniform distribution like a human eyeball lens. In this case, a third lobe group appears. The human optic nerve / image recognition is probably equipped with a mechanism that cancels out these side lobes. In order to eliminate the side lobe and use only the main beam, a gentler irradiation than the cosine distribution is required. However, since this is mainly used by emphasizing the center of the lens, NA becomes equivalently small and the width of the main beam becomes wide. After all, side lobes must coexist as a necessary evil. Even if there is a side lobe during recording, the heat region that exceeds the Curie point in the classical explanation is small, so there is no problem with inter-track interference. At the time of reproduction, it is only necessary to perform equalization with a PD array that cancels the side lobe like a human optic nerve.

Here, there is a method for slightly correcting the resolution limit law determined by the wavelength of the LD and the NA of the objective lens. The resolution is determined by the point light source, the objective lens without aberration, and the irradiation distribution. An actual LD is not a point light source, and the spot diameter is larger than the NA limit by the amount of phase dispersion. When examining multi-stripe LDs, there is electromagnetic coupling between two adjacent LD stripes, and stimulated emission is synchronized and the phase of radiation is the same. The phase relationship between the resonance currents of the two coupled LC resonance circuits shown in FIG. 22 is the same. The three LDs arranged in a row are fixed to a fixed symmetrical phase.

There are two ways to create a small spot without side lobes using the same wavelength of 405 nm and NA = 0.85.

1) Cancel the base of the intensity distribution of the spot imaged through the objective lens irradiated with the cosine distribution by the central LD with the opposite-phase spots on both sides, and cancel the side lobe. 2) Uniform distribution with the central LD To make the entire spot smaller by canceling the side lobes of the small spot imaged through the irradiated objective lens with opposite-phase spots on both sides

FIG. 23 shows the shape of a spot subjected to multi-stripe correction with a one-dimensional lens. The principle is that adjacent side lobes of radiation are in antiphase, so they cancel each other if the aperture is widened. It can be seen that the main beam is slightly expanded and the side lobes are reduced by the inverse correction of the aperture. The effect decreases with increasing NA. In an actual two-dimensional lens, it has a circular distribution (a uniform distribution results in a cotan distribution). From the beginning, the main beam is wide and the side lobes are reduced.

Expression 14 is an expression representing the mechanism.
The one-dimensional sidelobe attenuation technique shown in FIG. 23 is actually performed in two dimensions as shown in FIG.

Equation 15 is an equation representing the mechanism.

<Avoidance of dark lines>
The endurance of optical disc drives is determined

1) Growth of LD dark line 2) Tobacco smoke and other fine particles adhere to the lens

These two points are overwhelmingly more than other failures, and the significance of existence as a product is questioned. Of these, the adhering of smoke particles can be cleaned, but the only way to grow the dark line is to buy a new drive. Dark line growth can be foreseen in the initial aging of the LD and can be eliminated to some extent before assembly. It has been said that the dark line is a lattice defect that grows due to heat concentration due to excessive light emission. With an architecture that removes half mirrors, the dark line market aging failure rate can be expected to drop significantly. At the time of reading, switching from the LD operation with a large current to the LED operation with a small current can be expected to greatly reduce the failure rate. However, the only way to make the market aging failure rate almost zero is to switch and use multi-striped LD / PD. The dark line growth must be switched before growing to the next light emitting layer. The allowable shift distance for this switching is within the focal range of the objective lens shown in FIG. When viewed as a skew error, if the allowable angle of skew is 0.2 degrees, the allowable range is approximately 30 μm, which is multiplied by 1 mm of the operating distance and further multiplied by a / b.

Until now, it has been explained that the growth of the dark line, where LD dominates the life of the entire player, is a concentration of heat, but the truth is a little different. When high heat is applied, impurities re-diffuse and lattice defects tend to be repaired. In conclusion, this is not a heat problem. Let's reveal what is happening.

The light emission of LD is the vibration at the emission wavelength of all compound molecules in the active layer in the crystal structure. In response, all molecules that are not of the crystal structure of the objective lens made of plastic vibrate synchronously. Synchronous vibration of the objective lens, whose path length becomes shorter toward the periphery, causes phase concentration only at one point in the 3D space on the opposite side of the LD, and nothing else in the 3D space. Do not wake up. Even if it is the space between the objective lens and the focal point, nothing has happened there.

In other words, the total luminous vibration of the active layer is caused by the corresponding vibration through the intermediary vibration of the objective lens in the space where the spot of the phase change recording layer hits. The total vibration energy of the layer has a 1: 1 relationship with the total vibration energy of the spot in the phase change recording layer. This is not an Oliver snake side in which the radiated electric field from the antenna attenuates in inverse proportion to the distance, but has a 1: 1 point-to-point relationship. In the phase change recording layer, this vibrational energy is at a level that changes the crystal structure. This is the basic principle of recording. Therefore, the vibration energy in the active layer is at a level that changes its own crystal structure.

We must first respect this providence. It is contrary to providence that you hurt the opponent and you are unhurt. Don't think about the good things about such insects. If you are hunting and eating it, the first thing you should give thanks to is the testimony of the rich people. On top of that, if you tell yourself that you will have to erase, record and replay countless pits in the future, you will be allowed to live for the first time if you wish to live tomorrow.

This is because the band gap voltage of the crystal / amorphous intermolecular bond of the layer change recording layer or the band gap voltage of the intermolecular bond of the active layer is higher. If the molecule is large (if it is a polymer), a larger electric field is needed to give the same bandgap voltage. If the size of the active layer is 2 um x 1 um x 250 um, the total vibration energy is transferred to a solid space of about 0.4 um x 0.4 um x 2 um. The vibration of the spot space is immediately transmitted to the surroundings.

Even if the synchronous vibration of the active layer of the LD exceeds the band gap of the intermolecular bond of the compound, the crystal structure does not melt as it is. If there was no disturbance, he would pretend to be a crystal as if nothing had happened again. Even if the band gap of the intermolecular bond of the compound is exceeded, it is simply said that there is no constraint for the crystal to collapse at any time, and it does not actually move from the position of the crystal. It ’s like a rock, and if you do n’t actually step it, it wo n’t collapse.

Certainly, if there are impurities or small lattice defects, that will trigger growth. But darkline growth is a more fundamental occupational disease. In that sense, there is no point in eliminating lattice defects. To blame the growth of the dark line is like taking a break from school. It is necessary to correctly recognize the phenomenon that occurs and how much the electromagnetic field of the round-trip light exceeds the band gap voltage of the intermolecular bond of the compound. The physics of the 20th century has settled the hypothesis on the hypothesis, but the 21st century is all quantitative and must not have one point of cloudiness. Everything is a legitimate fact up to Galileo, without hypothesis, and must be built with certainty step by step.

In the classical form using a half mirror, the vibration of the active layer must be doubled by the loss. What is more ridiculous is that the reflectance of the reflecting mirror at the light emitting end face is 99% and the transmittance is 1%. If this is done, the energy over the active layer will be 99 times the energy that goes out of the end face and breaks the crystals in the phase change recording layer, and the standing wave amplitude will be 198 times. It is natural that the crystals in the active layer break before breaking the crystals in the phase change recording layer.

What is required of LD? That is, in the LED operation, the light emitted in all directions is changed to the LD operation, and the light intensity is set to about 100 as the directivity gain as shown in FIG. Along with this, the size of the point light source becomes much smaller than the LED. However, if the self-amplitude has increased 198 times, it is a fall. Increase the current above the threshold and release from the idea of switching to LD mode. Gradually increase the reflectivity of the reflecting mirror on the light-emitting end face to find the point to switch to LD mode. It is the correct design procedure to make it happen. The margin of N-times speed recording must also be fully considered.

Until now, people around the world can abandon and repair crying and repairing PCs and disk players with LD, OP, and disk drives that are incorrectly designed with a 20th century physics. I wonder if they have discarded things. There was no LD designer who wanted to reduce the reflectance of the reflecting mirror on the light emitting end face. There is no good thing. The Creator is terrible fairness.

As long as the laser diode is used for recording / reproducing of an optical disk, a resonance path length of about surface emission is sufficient. The transmittance of the light emitting surface should be as large as possible. In order to use a laser diode for machining or the like, phase-synchronized LDs may be driven in parallel.

<Pointer of surface emitting LD>
It is a mistake to think that lasers are making narrow beams effectively with long round trip lengths. This mechanism is a tandem phase synthesis radiation array, and if a narrow directivity is provided, the parallel phase synthesis radiation array can have a narrower directivity. FIG. 26 shows the radiation directivities of a 1000-wavelength cascaded phase combining radiation array and a 1000-wavelength parallel phase combining radiation array. The conventional red LD pointer is an edge emitting columnar phase synthesis radiation array, and wide radiation directivity is narrowed down to a thin beam by an epoxy package lens. The pointer of the parallel phase combined radiation array of the surface emitting LD has already been focused by the synchronized surface emitting itself.

Equation 16 is the directivity of the column phase composite radiation array.
Equation 17 is the directivity of the parallel phase combined radiation array.

<CSOP with synchronous surface-emitting LD>
21st century intrinsic physics brings the Creator's providence closer to people, and industrial product designers do as needed to create tools that cultivate the product technology that is supplied mainly to the world while mainly focusing on agriculture. Rather than building a store on a technical system built up like product design based on 20th century physics, it builds on the soil with usable materials. Let's show the difference in Figure 27.

All you need is light and eyes. If the active layer arrangement of a surface emitting LD array is arranged according to a certain rule, the astigmatism of the protective layer of 0.1 mm is corrected with a resolution corresponding to NA = 0.80 (square) to 0.85 (circular). And make a spot on the centerline. The functions of the two optical systems in FIG. 27 are equivalent. It would be nice to have a single piece of silicon chip and compound chip. This optical system can be used exclusively for reading / writing BDs, or it can be used for reading / writing CDs, DVDs, and EBDs. This 21st century ground solution optical system has no dark line matter.

Since CSOP (chip size OP) is lightweight, the distance from the disk surface is allowed to be 0.5 mm. Both pseudophysics and intrinsic physics require focus servo coil drive, tracking servo coil drive, and skew servo coil drive. A part-time engineer who makes world products while farming thinks on the soil. He knows that the Creator is ready to answer any problem. Even if you have never heard of the lens, you know the providence of the Creator, and go to the forest to find the answer that the Creator has prepared with paper and pencil so that the light concentrates in the pit. There is a sunlight through the forest, and it tells you everything about light.

FIG. 28 shows the spot shape within the 20 wavelength angle in the XY plane and the dimensions of the CSOP. In the surface-emitting LD array, all active layers are simulated with the same light emission phase. However, in the case of a progressive change, the XY coordinates of the active layer arrangement may be shifted according to the phase difference. The result will be the same. When the light emitting surface is circular, NA = 0.85, and the current is uniformly distributed. The beam diameter is smaller than that of conventional LD and circular lenses. What true physics brings is simple, there is no alignment of PD-LD like LaserCoupler, and servo control is simple as follows.

1) RF signal: (A + B) at the pit (refer to C and D at the mirror / pit boundary)
2) Tracking: At the pit (AB)
3) Focus: (A + B) at the mirror surface
4) Skew: (A-B) and (C-D) at the mirror surface

Phase-synchronized surface-emitting LD two-dimensional array If the arrangement of each active layer is selected, the combined phase light is concentrated at one point of the OP operating distance, and the focal length, skew, and tracking can be electronically adjusted and tracked by changing the current distribution However, in the ground solution, it is fixed electronically and servoed with an electromagnetic coil. The size of the LD array chip is 1.6 mm square, and the NA is 0.8 (square). The OEIC is a silicon chip and is 2.4 mm square.

Equation 18 is an equation for deriving the spot shape of the BD / DVD / CD on the XY plane, and the secret of the blending of the active layer arrangement is included therein to form a spot at one point.

<About aluminum layer surface reflection of pit surface>
Let's put a physical understanding of the reflection of radio waves and light by metal. Metal is considered a conductor with sufficient conductivity. In any case, the effective idea is to place a virtual image on the line contrast at the position of the mirror image across the reflecting metal, and pass a current in the opposite direction to the current flowing through the radiator. Then, the electromagnetic waves from these two radiators reach the surface of the metal at the same time, and not only the electric field in the tangential direction of the metal becomes zero near the surface of the metal, but also the electric field in the normal direction also on the surface. It becomes zero. Actually, a re-radiation current flows through the surface layer of the metal, and the sum of the radiated electric field is the same as if the radiation from the mirror image radiator was caused by the reverse current.

The reflected wave of the aluminum layer on the pit surface is re-radiation caused by the incoming electromagnetic field (light). In the early days when CDs were introduced to the market, coherent laser light sources were indispensable for optical discs, and the bright and dark images of pits were caused only by coherent light. believed it. After a while, a CD-R of a recording system in which the reflectance is changed with a flat layer was realized and widely spread. The developers of pit-type CDs, who say that coherent light is necessary or interference with pit light is the only method, do not correct mistakes arrogantly, but the history of optical discs remains unclear today . The term coherence was used to keep the ambiguity. However, this is neither accountable nor appointed at the time of recording or playback. The size of the spot diameter is independent of coherency. The only advantage that LD is used is that the front radiation ability is much larger than LED.

Re-radiation from the height difference pits and phase change pits forms an image on the PD surface through the objective lens, and what light and dark distribution is formed on the PD surface without passing through the lens is only re-radiation. It was decided by this theory that it was calculated with a very simple calculation. I would like you to make great use of it. It is the phase and amplitude of the incoming light that determines the re-emission. When the LD is used as the light source, the phases of the incoming light are the same. Even in LED light, the wave packet is longer than one wavelength, so the degree of brightness is the same as that of LD light.

Until now, people have become suspicious as to how much space a unit called a photon has, and so far, it has not been known by anyone that Schrodinger has revealed it. That is. With LED light, it is not understood that light and darkness can be achieved unless one photon spreads in time and space to the extent of the pit. However, if photons form a coherent group, they can escape from the difficulty of such explanation. This is history. However, if the fact that there is no difference between the light and darkness of the pits in LED and LD is pointed out, this time it will escape to the engineer group, not the coherent group. This is also history.

If the incoming light is a reference light for simple area illumination, an image of the pit surface appears on the PD surface through the objective lens with an NA limit resolution. The fact that the reference beam arrives at the NA limit through the objective lens is not directly related. When the reference light illuminates only the pit, not the area, this corresponds to masking the image on the PD surface. In a micro PD array, when each element captures a pit image, it is unnecessary that the image on the PD surface is masked, and the mask intensity distribution changes the signal, so the mask range is wide. Better. On the other hand, if the adjacent track is masked, the crosstalk from the adjacent track on the PD surface is reduced accordingly. This mechanism represents all of the essence of reading the optical disk.

Before being read by the PD, all optical operations contain phase information, which is zeroed by adding positive and negative light. However, after being read by the PD and converted to a direct current, both positive light and negative light become positive direct currents, and adding them does not become zero. The fact that this light can be zero if added is very important in the design of optical systems. All questions are solved when you hear that reflection is re-radiation from the aluminum layer. There is no light or electromagnetic waves.

<Physical principle of optical disk reading>
In the ground solution of optical discs including classical formats, LD is a reference beam that originally selects a spot, and phase-locked light has an advantage over an LED in terms of focusing and coherence. I haven't mentioned before. The only advantage of being phase-locked light is that the forward radiation efficiency is about 100 times higher than the LED. The reflected light distribution of height difference pits and writable phase change pits can be simulated very easily and accurately, so future optical disc development will be short in both 20th century intrinsic physics and 21st century intrinsic physics. It becomes possible to do in time. However, the optical disk of Tenjo Solution will replace BD from 2012 and eliminate the boundary between flash memory, DRAM and HDD. Tenjo Solution's optical disc does not require any special technical development, but simply returns to the origin prepared by the creator.

Reflection of light focused on a small beam spot creates an intensity pattern in the surrounding space. In Philips = Sony OP, this intensity pattern is condensed again by the objective lens, detected by the 4-division PD, and focus information, tracking information, and skew information are extracted in addition to the EFM modulation signal. This process is redundant. In order to detect these pieces of information from the reflected light, it is not necessary to go through the objective lens, and everyone should just pick up the reflected light. It was a 20th century physics tradition that did not make it happen.

<Reading Intrinsic-Beauty>
There is a surprisingly rational method as shown in FIG. 30 for reading out the pit information with the irradiation light focused on the spot. This is effective regardless of whether it is the 20th century type or the 21st century type, and can be called intrinsic-beat. In the mirror surface portion of the pit surface, the light with the light beam condensed in a cone shape strikes the mirror surface, follows the same cone shape, and is irradiated again to the objective lens. The intensity distribution of the return light is similar regardless of the section from the pit to the objective lens. Cut the cross section at the position of the objective lens for simplicity.

In this cross section, that is, the plane on which the objective lens picks up the reflected light from the disk, the necessary information is present as it is. In addition, the necessary information can be detected in the area outside the objective lens, except for under focus detection. Although it may seem like it is better to detect it in the center of the RF signal wave objective lens, it is an error. What is needed is a pit outline, which is all in the region outside the objective lens. This is natural when you think about it. This is because the reflected light exactly overlaps with the objective lens in the mirror surface portion where there is no pit, so there is no change, and if there is something on the disk surface, information will always appear on the outside.
On the other hand, in the place where the light is condensed again at the position of the LD, information is lost or is indirect information.

<Altitude difference pit and phase change pit>
As shown in FIG. 31, the basic pattern of reflected light is the same regardless of whether it is a height difference pit dedicated to the outermost line or a recordable phase change pit. If the spot diameter is smaller than the pit width, only the outline of the pit appears in the height difference pit, but in actuality, the light intensity of the area on the pit and the light intensity of the area outside the pit are about the same. In this way, since the effort is made to maximize the modulation, the height difference pits and the phase change pits have similar PD responses.

Outside light is blocked inside the optical disk drive, and the beam spot focused by the LD and the objective lens is applied only to the read / write pits. Therefore, the light in the internal space of the drive is characterized in that it contains no information other than pits.

<Size and frequency characteristics of PD array>
When the intensity pattern of the reflected light from the pit is imaged on the same plane as the LD by the objective lens, the area of the PD can be reduced, and the capacitance value of the PN junction is reduced. In the case where no lens is interposed, since the spread of the reflected light space is detected, the area of the PD is increased, and the capacitance value of the PN junction is increased, which hinders speeding up. Obstacles also usually provide an opportunity for differentiation when they are overcome.

In the OEIC, the ground capacitance of the PD is composed of a side PN junction capacitance and a bottom PN junction capacitance. Among these, the isolation on the side surface is replaced with SiO2, so that the capacity can be sufficiently reduced. The bottom surface increases the reverse bias voltage of the PN junction, widens the depletion layer, and lowers the concentration of the P layer and the N layer. Since the depletion layer is subject to drift, it is fast.

In Tengen-So, reading a two-dimensional pit makes the stress of speed 8 times easier.

<Analysis of reflected light at the pit>
FIG. 32 shows the angular distribution of reflected light in the Y direction that does not pass through the objective lens. The track pitch is 0.32 um, and the width of the pit stamped from the master disk exposed in the liquid having a high refractive index is changed from 30% of the track pitch. The spot illumination is a cosine distribution.

Formula 19 is an angle distribution of pit portion reflection.

<Mirror image alignment of PD and LD>
In the classic format of Philips = Sony, the quadrant PD is in a positional relationship between the light emitting point of the LD and the mirror image, and the alignment requires an accuracy of about 1 μm. This alignment is unnecessary in modern and modern forms. In the classical format, a 4-division PD cannot be made with a track pitch of about 0.32 μm, so a: b must be increased, and there is a limit to making OP smaller. There is no requirement for modern and modern formats.

<BD spot with Cosine distribution irradiation>
First, let's examine the beam spot by a lens with NA = 0.85 of LD of 405 nm. This relationship has been clear in a simple way for the first time, although no clear theory has existed in the past. This is the starting point of the correct optical disc, and it can be expected that the development of the optical disc will be extremely short. FIG. 33 shows a spot intensity distribution of BD of Cosine irradiation distribution.

Equation 20 is a two-dimensional distribution of spots.

<Consideration of a and b>
FIG. 34 shows a spot shape when both NA contributions a and b are considered.

Equation 21 is the response equation.

<Size of point light source>
A spot distribution is obtained by superimposing an image when the LD is not a point light source but the effective size of the active layer multiplied by the image magnification. The BD operates in this way. Although it depends on the definition of the spot diameter and the irradiation distribution of the LD light, if it is defined by the full width at half maximum, the spot diameter is a value obtained by dividing 1.2 times the wavelength by NA.

Formula 22 is an empirical formula of the spot diameter and NA. Although the wavelength is 1 / n in a medium having a refractive index, the pit depth is raised to 1 / n and can be seen from the upper surface. However, the spot diameter is D which is the same as the spot diameter formed in the air. Why? This is because the NA is reduced to 1 / n in the medium, so that the effect of the wavelength becoming 1 / n is canceled. When the light emitted in a liquid having a high refractive index is imaged and exposed as in the BD mastering process, the resolution increases.

<Spot shape unrelated to b>
As classical optical theory says, it can be seen from the calculation formula that the spot diameter is determined only by the wavelength and NA, and is independent of the lens diameter. FIG. 35 shows the spot intensity distribution when NA = 0.85 is maintained and the distance b between the objective lens and the LD pit is changed.

Expression 23 is an expression used for the verification.
It can be seen that the spot shape does not depend on b and is determined only by (1 / a + 1 / b), that is, NA.

<Uniform distribution irradiation>
FIG. 23 shows the two-dimensional intensity distribution of the spot when the objective lens is uniformly irradiated, and the equation is expressed by Equation 24. Even if NA of BD is not 0.85 but NA = 0.65, an equivalent spot diameter can be obtained at a wavelength of 405 nm if the LD irradiation is made close to a uniform distribution. Side lobes increase slightly.

<Outlined distribution irradiation>
When the reflected light is detected by a small PD that does not use a lens on the central axis without using a half mirror, the center of the lens or concave reflecting mirror cannot be irradiated with LD radiation. This hollow irradiation is equivalent to increasing NA. The main beam gets thinner and the side lobes get bigger.

The shape of the hollow distribution is shown in Formula 25.

<Role of 2-partition PD>
In the mirror surface portion having no pit, the intensity distribution with respect to the incident angle is reflected as it is. In the pit portion having a height of ¼ wavelength, the strength in the central axis direction is reduced, and the distribution on both sides is increased. In BD, the track pitch is 0.32 um, and the track pitch is stamped from a master disk exposed in a liquid having a high refractive index.

The reflected light distribution for pit detection is shown in Equation 26.

<Tracking servo>
In both the classic format of Philips = Sony that detects reflected light through the lens, and the modern / modern format that does not pass through the lens, the Push-Pull method of tracking detection cannot detect an error when the equivalent pit height is 1/4 wavelength. Tracking detection can be performed at some sacrifice in signal amplitude.

Equation 27 shows the re-radiation distribution of the tracking error signal.

<Focus servo>
When the optical system of the optical disk is operating normally, the beam spot of light is minimum, and the spot diameter increases regardless of whether it shifts in the direction of underfocus or in the direction of overfocus. Ingenuity is required to obtain character output. If the spot diameter is increased by shifting to either direction, the convergence logic that goes in the opposite direction and is optimal if the spot diameter increases by shifting to either direction is slow in response. Superimposing a wobbling signal affects the system. In the classic form of Philips = Sony, a method of obtaining an S-shaped output by an astigmatism method using two kamaboko lenses is generally used as the focus servo. . In the modern format, the defocused S-shape is detected by utilizing the shift of the focal planes of PD and LD. In the modern format, the amount of light entering the PD between the pit and the objective lens is detected as a linear change with respect to the change in the distance between the objective lens and the pit of the disc, and the information for S-crossing output that is zero-crossed is referred to. The reference of the zero cross is determined by the fact that the dark part on the optical axis of the reflected light at the pit part is the lowest in both pit high interference and phase change reflection. Regardless of the format, confirmation is performed by looking at the highest frequency component of the RF signal corresponding to the linear velocity.

Expression 28 is an expression representing the process of extracting the focus error signal.

<Solution of astigmatism balance sheet>
Astigmatism occurs in opposite directions depending on the thickness and refractive index of the protective layer of the disk and the length and refractive index of the active layer of the LD. If the refractive index of the disk protective layer and the LD are the same, and the thickness of the protective layer and the depth of the light emitting point of the LD are the same, the astigmatism of the two will just cancel out. Actually, the astigmatism is designed to be zero in the four components of the aspheric lens, the protective layer, the half mirror, and the LD. In addition to this, the addition of an astigmatism correction lens is a redundant design.

It is impossible to realize a 3-way OP that reads and writes a CD / DVD / BD differentiated into three wavelengths of 780 nm / 650 nm / 405 nm with a single wavelength. This is because the requirement of the tracking error signal is 0 to 1/4 wavelength, and the condition is not satisfied with a single wavelength. Therefore, the problem is whether or not CD and DVD discs prepared at wavelengths of 780 nm and 650 nm can be read and written at a single wavelength. In that case, since 780/650 = 1.2, there is no problem with respect to the pit height. The only problem is that the thickness of the protective layer is 1.2 mm for CD, whereas it is 0.6 mm for DVD. As a matter of course, a shorter wavelength is advantageous, so 650 nm is selected.

No special optical components or special means are used to change the astigmatism, which seems to be unmanageable to increase the protective layer from 0.6 mm for DVD to 1.2 mm for CD by +0.6 mm. There is only one way to counter. It changes the ratio of a: b twice between DVD and CD under the same lens focal length. Then, even if the thickness of the protective layer on the optical disc side changes twice by DVD / CD switching, the LD side appears to have a constant protective layer thickness, and astigmatism is balanced on both sides of the objective lens. . In addition, the spot diameter can be made 2.2 times the spot diameter of DVD (= 1600 nm / 740 nm) by returning to the side that gives a little astigmatism in the CD mode, and is made from LD light of 650 nm. The response is a beautiful spot shape without side lobes compared to a response made from 780 nm LD light. FIG. 41 shows the principle.

Thus, as shown in FIG. 42, a spot for DVD and a spot for CD could be created with a single InGaAlP 650 nm LD and a single lens.

Expression 29 is an expression corresponding to thickness switching between 1.2 mm and 0.6 mm.
In addition, astigmatism on both sides of the objective lens cancels each other positively and negatively, an aspherical lens and astigmatism neutral are achieved, and astigmatism correction for each BD / DVD / CD is not required. In this way, CD / DVD / BD read / write 3WayOP is performed at two wavelengths of 650 nm and 405 nm of two light sources as shown in FIG.

Table 1 shows the astigmatism balance.

<Skew error>
When the OP is small and light and the objective lens, PD, and LD can be driven as a unit, the skew error is that the optical axis of the OP and the pit surface of the disk are not perpendicular to each other. Asymmetry around the optical axis of astigmatism appears and cannot generally be corrected. Therefore, the attitude of the OP is controlled by two axes XY so that the surface of the protective layer is always perpendicular to the optical axis. It is synonymous with having to do. In addition, when the pit surface is tilted with respect to the optical axis, the reflected light deviates from the objective lens, but this is not a big problem. FIG. 44 shows a spot shape when there is a skew error.

Expression 30 is an expression representing the two-dimensional distribution of the skew error angle and the spot on the XY plane.

<Modern form of OP>
The classic form of OP is

1) Both the path from the LD to the pit surface and the path from the pit surface to the PD pass through the objective lens. 2) The center of the LD end face coincides with the center of the PD region, and the two paths are equally focused. 3) Half mirror The light emission center of LD and the center of PD are mirror images.

The conventional OP is uniformly this system. However, this method is redundant. One modern form OP is

1) Both the path from the LD to the pit surface and the path from the pit surface to the PD do not necessarily pass through the objective lens. 2) The center of the LD end face does not coincide with the center of the PD area, and the two paths are not equally focused. 3) Not always using a half mirror

Since the modern format is lightweight and compact, the objective lens, PD, and LD are integrated, and the entire optical unit is driven by a tracking servo and a focus servo so that the pit surface is captured at the light convergence point. The feature of this type shown in FIG. 45 is that the positions of PD and LD are shifted back and forth on the optical axis. In addition, tracking servo, focus servo, and skew servo are performed with a 4-part PD of A / B / C / D. The modern form is one of the natural solutions without waste. During recording, the light emission point of the LD and the pit surface of the disc have a just-focus relationship. The function of quadrant PD

a) Focus: (A + B)-(C + D) S-shaped output of mirror surface irradiation
b) Groove tracking: CD of pit part irradiation
c) X-axis Skew: AB of mirror surface irradiation
d) Y-axis Skew: CD of mirror surface irradiation

It is.

During playback, the pit surface and the PD surface are in a just-focus relationship. The LD light becomes overfocused on the pit surface and becomes reference light for the region. The difference in brightness of the tracking error is detected as CD. The focus error signal is (A + B)-(C + D) and an S-shape is output. The RF signal is detected by adding A to B with a delay inversely proportional to the linear velocity. Since the return light to the LD spreads with the light beam defocused, disturbance of the resonance operation of the LD does not occur.

The advantages of the modern format are

1) When the half mirror is omitted, the light quantity of the LD is not halved. 2) The high accuracy of alignment between the center of the PD region and the center of the LD end face is not required. 3) The effect of skew error Insignificant

And the disadvantage is

4) If a half mirror is not used, the PD array cannot be made into a single chip.

It is. However, as shown in FIG. 46, when b can be increased, the edge-emitting LD can be piggybacked on a single PD array chip.

<Modern lens>
The ground solution uses an LD and a rotating disk as the light source, while the ceiling solution uses an LD or LED as the light source, and the disk is not necessarily a rotating disk. All optical disk optical systems currently in circulation are Philips = Sony type ground solution / classical form, and LD and PD are in a mirror image relationship via a half mirror. This is the most primitive of the ground solutions. The ground solution is based on the premise that one LD is the pit surface and the beam spot is narrowed to the NA limit. On the other PD surface, the classical format presupposes that a pit image is formed when the LD is used as the reference light. is not. Moreover, it cannot be said that an objective lens is necessary for PD. A modern format versus a modern format is one in which a PD array is placed between the objective lens and the disc. Of course, there is no half mirror, and the radiated light from the LD is reflected by the mirror surface of the disk and returns to the active layer of the LD. This type of OP is extremely thin. FIG. 47 shows two examples of modern format 1 and modern format 2.

<Modern PD array>
A modern type PD array that detects the reflected light from the pit surface before passing through the objective lens is slightly different from that of the modern type that detects the reflected light from the pit surface forming an image of the pit through the objective lens. In the modern format, the reflected light has only pit information as a point, whereas in the modern format, several tracks are illuminated as areas, so a pit image is formed on the PD surface to create a fine image like a CCD imager. Will be detected. In both methods, the amount of light that determines C / N is sufficient. In the modern format, the image is not reflected light but a spot as illumination light.

The tracking error signal has the form shown in FIG. 48, and the distribution is shifted depending on the radiation angle. Therefore, two PDs having a large area or PDs having a small area may be detected, and AB may be detected. This error signal appears when there is a mark pit and does not appear on the mirror surface.

The RF signal is simply detected as A + B. A PD pair arrangement is selected such that A + B does not change even when tracking is shifted.

Focus error signal detection must be designed most carefully. The reflected light from the mirror surface picked up by the PD is inversely proportional to the square of the distance between the pit surface and the PD array. Therefore, it can be seen from the change in the amount of light of A + B whether OP is relatively approaching or moving away from the pit surface. However, if the operating distance is 1 mm, a change in depth of 10 μm will only result in a 2% change in light quantity. The reflected light is reduced at the pit portion, and its bottom value is a function of the spot size, pit height, and pit width. When the VCM drive passes the just focus point, the bottom price change turns back. A focus servo is formed by these two A + B signal processes. In addition, a high-frequency component corresponding to the linear velocity is detected, and the bottom price information is helped as turning information. The depth of focus is typically shown in FIG.

In an optical system that requires skew adjustment, a skew error can be detected by taking the spillover of the reflected light cone from the objective lens and taking the difference between the four outer PDs (X1 / X2 / Y1 / Y2).

<Modern format 1>
The modern form of OP is to separate the classic form of Philips = Sony into an essential one and a conventional one, and eliminate the conventional one.

1) There is no essential meaning in matching the light emitting point of the LD and the center of the divided PD with accuracy of several u like a laser coupler. If the information indicating whether the spot of the narrowed LD light is at the center of the track is reflected on the PD, it is sufficient. There is no advantage of re-spotting by putting a lens in the middle of the light reflected from the pit surface to the PD. The selection is already made when the spot of the LD light hits the pit surface.
2) Irradiating the objective lens with the cosine radiant light distribution from the LD is not optimal for producing a small spot. It is better to emphasize the outer edge.
3) When the LD light is reduced by the half mirror, a larger current is required, and the life of the LD is shortened by the growth of the dark line.
4) The lens has chromatic aberration, which becomes an obstacle of 3 WayOP.
5) To ideally drive the entire optical system integrally, we want to make it compact and lightweight.

<Modern format 2>
The modern type 2 has the same concept as the modern type 1 that uses a concave reflector, but it can be made thinner and lighter because it uses a flat lens. Even if it is called a flat lens, it is a degenerate reflecting mirror and has no chromatic aberration. Planar lenses are not lenticular lenses that use refraction. The key point that can realize this is that the two-dimensional impulse response from the point light source to the condensing point is the same as that of a normal continuous lens even in a set where reflection is performed in a small discrete area. All the light emitted from the LD is collected at the condensing point except for the spillover to the conical diffuser. The modern type 2 flat lens is a plastic molding with an aluminum film. The miniaturized mirror does not generate alias. It is divided into concentric circles or spirals as shown in FIG.

<Enhanced-BD>
Enhanced-BD (EBD) is an optimized BD operating condition and uses the same wavelength of 405 nm as BD. The lens is NA = 0.85 for a circle and NA = 0.80 for a square. The track pitch is 0.24 μm while BD is 0.32 μm. Since the longitudinal direction is a mark length that is 1 / 1.2 of the BD, the recording capacity of the BD is 25 GB, whereas the recording capacity of the EBD is 40 GB. FIG. 51 shows the format.

There was no progress in the 20th century concept between BD and EBD, and the basics of the physical principle were understood correctly, and the optimization of the system and the margin of operation could only be realized by simple calculations. In BD, physical crosstalk compensation has not been pursued deeply and has relied on PRML. In EBD, the beam distribution was obtained accurately in a short time, and the physical layer was optimized. In conclusion, BD has 60% of unexplored margin, and it can be said that the work to be done was not exhausted. Since the BD can read and write the EBD, the two are not in conflict.

At the time of recording, the emitted light of the LD is just focused on the pit surface, and the PD detects the tracking error signal of the push-pull method and the focus error signal in addition to the RF signal. During reproduction, the emitted LD light becomes reference light for irradiating the area on the pit surface, and the pit row forms an image on the PD surface. Inter-symbol interference compensation during playback of the EBD in the longitudinal direction, which is performed purely in the physical layer, is much stronger than PRML, but strong interference compensation is also performed during recording. It is similar to a method of making a time delay signal negative and adding it to the original signal for the afterimage correction of the LCD. When the inter-symbol interference which is known in advance is made negative and added to the output of the main PD, the brightness DC bias does not lift up the black DC bias in the LCD afterimage correction, resulting in a level immovable section. On the other hand, since this method can apply a DC bias, interference can be corrected even with a small size.

FIG. 54 shows the correspondence between the PD array and the area irradiation.

FIG. 55 shows area irradiation light. In EBD, the reference light for pit area irradiation at the time of reproduction is performed by defocusing the beam focused at the time of recording by the irradiation area. In this case, if the NA is large, the influence of side lobes around the main beam that was originally narrowed during recording remains, and the region irradiation light has some unevenness. This unevenness must be reflected in the weighting of the equalizer during playback.

In the EBD, all side lobe responses that cause problems around the main response peak of the pit image on the PD surface are two-dimensionally canceled out. Conventionally, all of these sidelobe information is truncated, and the truncated information cannot be recovered no matter how much effort PRML makes. BD has truncated 60% of the information received. The operational stability of BD and EBD is comparable. A one-dimensional PD array is arranged at a position corresponding to an adjacent track, and a plurality of outputs through a variable delay line are linearly combined as shown in FIG. 56, so that the delay amount is proportional to the reciprocal of the linear velocity of the disk. Is made proportional to the linear velocity. The sum of the magnitudes of all sidelobe responses should not exceed the magnitude of the main beam response.

<Mechanism of phase change recording>
So far, understanding and explanation of the mechanism of phase change recording has been unclear. If the truth is not revealed, the optical disc remains a 20th-century relic. 20th century physics says: The laser beam spot irradiates the phase change thin film and the substrate by receiving the energy of the light, and if the temperature of the phase change thin film and the substrate is above the Curie point, it becomes amorphous when it is rapidly cooled. When slowly cooled, it becomes a crystal.

Isn't that strange? First, if a phase change film that is assumed to have a large thermal resistance with the substrate receives heat or becomes high temperature, the heat cannot easily be reduced by conduction, radiation, and convection. Therefore, rapid cooling is not possible. What is the recordable disc designer, whether the relaxation time of rapid cooling is the time that the spot is over the shortest pit length, the time of one round of the track, or the time that the whole disc cools longer than that Can't even answer. In addition, the phase change thin film in the crystalline state has a high reflectivity, and isn't it possible to receive the thermal energy that 20th century physicists say? If the relaxation time is long, the remaining heat causes inter-track interference during recording, resulting in blurred recording. Where does the heat go?

Next, if it is assumed that the phase change film with a small thermal resistance between the substrate and the substrate is also warmed, the heat conduction, radiation, and convection cannot be performed immediately. The shape of the spot that exceeds the curie point spreads. The reason why the phase change recording phenomenon is interpreted as quenching is understood only by the nature of the material being tested in the laboratory. It is just a story that Obshinsky interpreted as such. In this way, physics in the 20th century was an irresponsible study that was far from the truth.

Optical recording is not a thermal process. If you put something containing moisture in the microwave, it will warm up. In this case, heat is generated as a result of the diffusion of vibrations, and what happens is that everyone understands and agrees that the molecular linkages are vibrated by electromagnetic waves. Phase change means that when the vibration exceeds the band gap of the molecular structure and eventually the vibration becomes smaller, it is aimed at either crystal or amorphous like a flip-flop circuit. How do you control it?

What can be surely crystallized is that the homogeneous light is reduced gently (not to mean slow cooling) below the band gap voltage. What can be reliably amorphized is to reduce the turbulent light while maintaining the turbulent light below the band gap voltage (not slow cooling or rapid cooling). But we don't have disturbed light. When the LD is in the LED mode, the light is random with a slightly larger spot diameter, but the intensity becomes 1/100 and the band gap voltage of the phase change material cannot be exceeded.

Therefore, the heat (ie noise) around the spot of the phase change film is used to make it amorphous. After irradiation of a uniform spot that supports the crystal structure as it is, it becomes amorphous if there is sufficient time to intersect with the surrounding noise vibration. It is the opposite of rapid cooling.

Quenching is a laboratory story, where the phase change material is heated to high temperatures with simple heat, in which case the material vibrates loosely, and if it cools slowly, the molecules form crystals themselves and settle down. This is the case when the bandgap voltage becomes shortly before the autonomic action of molecules forming crystals occurs when rapidly cooled. This is a completely different process from what happens with phase change erasure / recording.

Why is rapid cooling during recording, and erasing performed at half the current is slow cooling? The reality is the opposite. It is natural that it takes longer to cool down from the high temperature to the same temperature. The physics of the 20th century is a ridiculous escape. If you don't know, you can be honest. If everything is explained in plain words with no cloudiness, it is correct physics. There was no such thing in the 20th century. If you can explain 99% but not 1%, it's 100% wrong. I think that 99% of the explanation is based on wrong assumptions. Based on the correct assumptions, it is always 100% accountable.

Temperature is just the fact that molecular bonds are oscillated by electromagnetic waves, not anything else. When a minute thermometer without heat capacity is put in the spot of light, the temperature rises, and when it goes out of the spot, the temperature drops. If the thermometer's heat capacity is zero, there is no time delay in temperature rise and fall. That is, it can be said that the temperature is high or low is not the air, the substrate, or the phase change film, but the light spot itself. Perhaps 18th century people understand this easily, and neither engineers nor children can easily understand it today. Because it is so educated. It is a different aspect of heat or the result of a process. What we want to do now is to rearrange the crystals of the phase change film. To do this, the band gap must be exceeded once. Crossing the band gap is the vibration itself. Vibration is also called heat. But heat is not a purpose or means. The purpose is recombination and the means is vibration. It is not a thermal process. Heat is a disordered state, and when it is irradiated with LD light, it vibrates in an orderly manner. The difference between the wavelength of the LD light and the lattice of the phase change film is irrelevant.

If the reflectivity of the phase change thin film in the crystalline state is 100%, all of the irradiated light is reflected and cannot receive what is called thermal energy in the conventional energy theory. At best, the spot of light warms the surrounding substrate, which can only conduct and warm the phase change film. In this case, the recording spot is not formed into a small circle. Why didn't you question this? However, I think that the aluminum reflective layer of the optical disk and the crystalline state of the phase change material reflect almost 100% light, so I think that it receives almost no energy, because I have a lot of expensive crude oil, it ’s rich, the nuclear warhead It ’s as humorous as it ’s intimidating because it ’s strong. Reflection is re-radiation from a metal film or a film in a crystalline state. The state of 100% reflection is the strongest in metal films and crystals, and the re-radiation current (vibration) flows in response to light irradiation. On the other hand, in the state where all the light is absorbed (black), the intensity of the re-radiation current flowing in response to the irradiation of the film is 50% of that in the case of reflection. This is important first.

I hope both new discoveries and correct physics understandings. But there is no chance. All the physical principles have now been solved to form the physics of the 21st century. From now on, all the phenomena of new materials can be confirmed by Computer, so there will be no accidental discovery and no mistake in explanation. The creator had prepared in advance so that all problems could be solved by only a combination of analog amounts +1 and -1.

The recording material film that selectively uses crystal and amorphous can be made compatible with 3-head that can be erased, recorded, and reproduced without exception. No more writing errors on the optical disc.

<Erasing and recording of phase change film by Futakoyama>
Erasing / recording can be performed by using the two-stripe LD shown in FIG. Since the spot diameter effective at the time of recording is a portion exceeding the band gap, the recording spot formed by light having a wavelength of 405 nm is reasonably small as compared with the spot diameter defined at the time of reproduction. The side lobe size must be less than half of the main beam. Erasure occurs at the preceding minor peak. Further, the secondary peak may erase the preceding pit of the same track, or erase the adjacent preceding track and give time for one round between recording. The role of erasing is to level the previously recorded pit string, and applies a uniform vibration slightly exceeding the band gap to fix the grid before disturbance from the periphery enters. Immediately after that, the same recording level of light may be given.

Further, erasure, recording, and reproduction are simultaneously performed at the triple peak shown in FIG. Simultaneous erasure-recording-reproduction may be performed on the same track, or the tracks may be shifted one by one.

<Velocity Modulation>
By applying velocity modulation in the longitudinal direction to the beam spot during recording and flowing the spot by rotating the disk, it is possible to prevent the resolution from being lowered due to the aperture effect. In FIG. 59, in an LD composed of four active layers that are phase-synchronized, the intensity of the resonance is modulated rather than the phase of the four resonance channels, and the beam is swung to follow the rotation of the disk, thereby increasing the irradiation intensity equivalently. Is. Also, if you want to increase the rotation speed at the N-times speed for recording / reproduction, but if the light irradiation per writing pit is insufficient, increase the number of channels in the active layer of the LD and increase the rotation speed at the N-times speed. In addition, the generation of LD dark lines can be suppressed.

<Construction of modern 3-way method>
If the LD is not divided into two wavelengths of 405 nm and 650 nm in terms of coherence of the pit height and cancellation of astigmatism due to the plate thickness, 3 Way recording / reproduction cannot be realized with the light source wavelength. Single means that a common NA = 0.85 lens is used. If the irradiation angle from the LD is smaller than the lens, the NA is also small. Although the objective lens is optimized to a wavelength of 405 nm and NA = 0.85, there is no problem because the spot diameter is large even if it is not optimal for CD / DVD. Since the only obstacle to the single configuration is the pit height, when the CD is left as Legacy, it is appropriate to lower the pit light of the newly produced CD as shown in FIG. In general, you can still read the CD with a conventional player.

In the 3W way of the modern format, as shown in FIG. 61, the A / B / C / D PD array is commonly used for CD and DVD. The defocus amount, that is, the spot size is determined by the threshold when the focus error signal (A + B) − (C + D) is input to the comparator.

<Actual of modern format for BD>
The modern form is a combination of a convex primary reflector and a concave / planar secondary reflector. Optical plastic lenses have refractive index dispersion (chromatic aberration) with wavelength, but modern forms that use only reflection have no wavelength dependence. FIG. 6258 is a configuration diagram of an optical system for BD. In the modern format, the secondary reflector is generally fixed as a relative relationship with the disk surface, the primary reflector is movable, and the focus servo, tracking servo, and skew servo can be applied.

FIG. 63 shows a simulation result of a beam spot and tracking error in a modern type of hollow irradiation.

<Modern 3 Way conversion>
Modern-type OP CD / DVD using a reflector with a shortened optical axis and BD-compatible 3Way use two LDs with wavelengths of 650 nm and 405 nm. In BD, a spot with a wavelength of 405 nm / NA = 0.85 is just focused. In the case of DVD, a spot irradiated with a wavelength of 650 nm / NA = 0.60 is just focused, and in the case of a CD, the spot size is determined so that the depth of the cut in the bit part is constant with a necessary defocus amount. The PD is placed in a common area between the objective lens and the disc. FIG. 64 shows a modern three-way configuration using a half mirror.

FIG. 65 shows a beam obtained by defocusing a cosine distribution irradiation spot. In fact, the modern form is a hollow cosine.

Formula 31 is a defocusing process.

<EBD practice>
The EBD is a rectangular lens with a wavelength of 405 nm and NA = 0.80, which reduces the cross-sectional area of the light emitting end of the LD, widens the radiation angle, allows irradiation spillover, and brings the BD asymmetric cosine distribution closer to a uniform distribution. Yes. The resulting sidelobe response is equalized by adopting a modern format that switches to area illumination during playback. As a result, a recording density of 40 GB is stably achieved. Since the side lobe does not reach the curie point during recording, it is fine with a sufficient margin. The reason why the recording density is 1.6 times while having the same NA at the same wavelength as that of the BD is that the equalization is performed by switching to the area irradiation at the time of reproduction. EBD does not use a half mirror, and the distance between LD and PD is increased correspondingly to create a spillover to bring the irradiation closer to a uniform distribution. The return light disturbance is defocused both at the time of recording and at the time of reproduction and does not become a problem. Since the half mirror is not used, LD light is emitted from the center of the PD array as shown in FIG. 67. For this reason, the RF signal detection of the main beam is divided into two PDs as P1 and P2.

The EBD increases the recording capacity of the BD by 60% while maintaining compatibility with the BD, and the increase of 33% of the EBD cancels the crosstalk between tracks by the fine PD array. The direction of the linear velocity is increased by 20% by equalizing the amount of side lobe that is increased by narrowing the main beam.

<3.5-way EBD conversion>
In order to use an LD / PD / aspheric lens optimized for EBD at a wavelength of 405 nm or an EBD equalizer for a BD that does not have an equalizer, the space between the pit surface and the PD array surface during reproduction is used. If it is slightly defocused, almost the same response as BD can be obtained. Similarly, defocusing may be performed during recording. This aspect is shown in FIG.

DVDs and CDs that are compatible with DVDs using a wavelength of 650 nm may be defocused as much as necessary for CDs.

Although the relationship between BD and EBD can be compared with the relationship between VHS and S-VHS, EBD is not achieved unless the pre-groove of the blank disc is a track pitch of 240 nm. If the LD is 3 stripes, erasing / recording / reproduction like a tape recorder becomes possible.

<Just focus area in XY plane of aspherical lens>
By the way, in the form where the beam spot is defocused at the time of reproduction and the area is irradiated for several tracks, and the resolution depends only on the NA limit between the pit and the PD, the object is not a point in the relationship between the object and the real image. The spread of dots. FIG. 65 shows how much the NA limit intensity distribution is distorted by the aspherical lens when this spread is away from the optical axis. As the microscope with a large NA has a wide focus area, there is virtually no distortion at the spread of several tracks, as it is not only around the optical axis. This can be easily understood even with a microscope with a large NA, since a relatively wide range appears to be in focus.

Expression 32 is an expression for checking the focus shift in the visual field range.

All living creatures in the world use the retina to recognize images with side lobes in this focus area. Plants appeared on the primitive earth, from which animals like worms were derived. At first, he preyed on something that touched the tentacles, but eventually the tentacle-predation chain mechanism became a neurotransmission. At this stage, the nerve junction could not be the brain. In the shallows where the light reaches, the base of the tentacle is the retinal prototype, and its surface protrudes to allow light collection. In this case, since the recognition on the retina is inverted with respect to the recognition by the tentacles, it is necessary to twist the nerve in order to overlap the sense of the tentacles and the visual information. This twist mechanism eventually induced a mutation with two light-collecting lines, and the distance to the prey became known. On top of this foundation, the information processing organs of the brain developed slowly and slowly. In this process, it was not logical that 1) the optic nerve had to cross with the brain and 2) it had to be divided into the right and left brain. This is why the eyes are formed ahead of the brain during the development of organisms. The brain is just a detector at the base of two eyes. PRML is a gorgeous fantasy organ behind a poor eyeball. Even if you do your best with PRML, it is 25 GB, but if you take care of your eyes, it will be 100 GB. We must first have a good eyeball. The NA of the eyeball is not large. If there are two eyeballs, the distance from the pit surface can be accurately determined by parallax.

<All-Form-Optical-Pickup>
Table 21 shows the specifications of the ground solution optical disk. There is no problem in reading and writing BD with OP of EBD. A conventional BlueRay recorder cannot read or write an EBD disc. The problem with reading and writing DVDs and CDs in EBD AFOP is the pit height. If the DVD and CD playback pit height does not cause interference at a wavelength of 405 nm, the pre-groove depth of recording is high. The pit height is freely set by each company. Therefore, AFOP must use two wavelengths of 650 nm and 405 nm.

<Between light and electromagnetic waves>
This article removes the wall between light and electromagnetic waves at the product level. Light is not particles or waves. There is no so-called wavy or wave duality. It was Isaac Newton in England who thought the light was a particle, and Christian Huygens in the Netherlands thought it was a wave motion over time. Even if light is handled as particles or light is handled as waves, optical discs cannot be designed correctly, but remain in the 20th century classical format, which is a tedious activity of shortening the wavelength. Both optical disc design and radio wave transmission / reception antenna design are completely different from those of the 21st century when released from waves, particles and duality, and the ugly Yagi = Uda antenna and parabolic antenna disappear. The 20th century was a 100-year period in which new hypotheses were prepared and proliferated in addition to explanations of hypotheses. The founder of the mistake is Newton, but the chain erupted from the photon theory.

As shown in FIG. 70, it is well known that the radiation pattern of light or electromagnetic waves does not change as a far field between the far and middle. This cannot be explained by Huygens' wave theory. This is because the radiation pattern is not maintained if the wave source produces the next wave source. So wave theory is wrong.

On the other hand, the NA limit of OP and the wraparound of radio waves in the shadow of a building cannot be explained by particle theory. So the particle theory is wrong. Light and radio waves are neither particles nor waves. Light and radio waves are remote interactions with elementary particles and elementary particle delay terms. Fortunately, the Bio-Savart rule can explain the phenomenon quantitatively even if it is not based on the wave theory. In comparison, Schrodinger's wave equation and Maxwell's differential form are wrong or not useful. They are prepared to explain the existence probability, and only formulate what Huygens says, not the essence of things. The radio waves sneak in the shadow of the building because of the re-radiation from the current flowing in the objects that make up the building by the incoming electric field. Richard Feynman knew this.


A mysterious mechanism that is maintained even when the radiation distribution is distant and has never been revealed to anyone is as shown in FIG. 70, Expression 33, and Expression 34. It is no wonder that Oliver Snakeside misunderstood the light as particles. The magic of the phase difference is in the form of particle dissipation of energy.

There is another formula mechanism. It is a parallel array shown in FIG. The reason why the streak of light can be seen between the leaves of the tree is not because the leaves of the tree cut off the sunlight. The re-radiation from the leaves of the tree forms the streaks and shadows of the light. It is inevitable that Newton thought light was a particle. This stunning parallel array is the trick. No one can be deceived by this.

The interference fringes of light due to the double slits and the interference fringes of electron beams due to the double slits are not because photons or electrons pass through the two slits indefinitely using the technique of alternation. It is just a re-radiation from the screen where the continuity breaks at the slit. Although this is well understood as a slot antenna, the optician who was involved in Erwin Schrodinger's hypnosis does not interact with radiologists. Richard Feynman was unaware of this.

Newton's law of action / reaction is wrong because the object-to-object interaction is delayed by 27.4 billion years to and fro 13.7 billion light-years. Energy can be defined only when there is a reaction to the action (a reaction of current to the action of applying a voltage). If the reaction is delayed by 27.4 billion years, energy cannot exist. Energy is the idea of profit, loss, desire, savings that began in the industrial revolution. But the actual cosmic principle is an hourly payment without a reminder. A light bulb can be turned on by collecting radio waves emitted by someone from the end of the universe. If it's 13.7 billion years, you might not want that person anymore if you want to return the debt. The law of conservation of energy only interprets one aspect of the phenomenon in my own way.

The British Oliver Snakeside explained that the pointing vector, which is a flow of energy, radiates, but this can be classified as a particle theory. He said that he could receive energy with an equivalent cross-sectional area and extract power from it, but neither small antennas nor large antennas would change power, and the pointing vector theory was incorrect. Magnetism and electricity are other aspects of one thing.

Regrettable Newtonian mechanics are unfortunately wrong, except for the law of inertia. In addition to the law of action and reaction, F = mα is also an error, and the law of universal gravitation is also an error. The universal gravitational constant G can be accurately calculated by Equation 35. rB is the Bohr radius and rU is the Big Bang sphere radius (13.7 billion light years). The universal gravitation constant can be calculated from the Big Bang age of 13.7 billion years.


This is just one example, but 21st century physics already reveals everything in the universe. Attraction is not caused by a fictitious Higgs particle, but is a force that tries to counteract de Broglie waves due to expansion of 10 80th proton-electron pairs in the big bang sphere with de Broglie waves of the object movement due to attraction. That is precisely guided. The Big Bang age measured by the Hubbs Space Telescope is estimated to be 13.7 billion years +/- 200 million years, but shouldn't waste money on the launch of LHC and telescopes and should invest funds to maintain the global environment. This is because the age of the universe can be accurately calculated from the universal gravitational constant that can be known on the ground. G is decreasing at a rate of 13.7 billion per year. It is wise for the United States to cease Devatron, a linear collider. One of the low expectations of LHC is a clue to dark matter. But it is a nightmare created by imagination.

The reason why early astronomical astrologers had to assume dark matter is that the motion of celestial bodies does not conform to the inverse square law of universal gravitation distance. The current astronomy level is to bring out invisible dark matter that fills the universe and crosses the red lights in groups. It was calculated that the MOND hypothesis of Israel's model Hymir Grom disagrees with this, and that the dark matter hypothesis is unnecessary if the power of 2 in the square law is changed. However, this is only the person who made up the hypothesis with a new hypothesis, like Hideki Yukawa. The providence of the Creator is simpler, only G is decreasing at a rate of 13.7 billion per year. The numbers match, and the dark matter becomes a black joke.

Physical science, which was right up to Galilei, began a chain of mistakes with Alchemist Newton. Einstein's E = mC2 is said to be wrong because the right side and the left side repeat the same thing. Feynman called Einstein's m the electromagnetic mass and took one step closer to the truth, but left another 99 steps. The relative velocity when a proton collimated eastward to 99.99% of the speed of light by a linear collider and an antiproton accelerated westward to 99.99% of the speed of light is 199.98% of the speed of light. The boundaries of the Big Bang sphere are moving away from the Earth at the speed of light, but most astronomical physicists affirm the speed of light when they are away from us at the speed of superlight, but not related to us. Where should Einstein's principle of relativity go? When you are buried, you must give a proper lead.

Einstein's theory of light quantum is wrong. Orbital electrons and free electrons are equally oscillated by the incoming electromagnetic field. It is just a story that says that it is a floating stone that cannot be said to be restrained. And if the incoming electric field leaves, it can be said that it is not free from the nucleus. Quantum processes are a picture. If there is a quantum process in the universe, it will be full of noise and radio communication will not be possible. The concept of photon is that electrons are shielded as long as they are in orbit. Naturally, the uncertainty principle of Berner Heisenberg is also wrong. PD does not capture incoming light indefinitely. This is obvious when the amount of noise is measured. Quantum behavior is not incoming light or electromagnetic waves, but only the fact that there are several stable points of orbital electrons around the nucleus, as shown by Fugang Pauli. In any case, physics has already been solved almost completely accurately for the 21st century. It was a wonderful world of creators where only the surprisingly simple analog quantities 1 and -1 created all things. In addition, the Creator has embedded the eternal story in the universe.

Those who handle optical discs cannot design correctly unless they understand these principles correctly. The top solution is based on the very simple principle originally given by the Creator. People do not need to invent and discover themselves, and appear naturally before what natural solutions believe in with a correct understanding of the principles.

<Application of BD / EBD>
In order for the image display device to give a feeling that a human is in nature, the number of pixels of about 7680 × 4320 is required. This is called natural vision, 3840x2160 is called supervision, and 1920x1080 is called high vision as usual. An optical disc capable of recording for 2 hours is required for each. Supervision-compatible optical discs are 12cm diameter discs and multi-bit recording of top solutions. The natural vision compatible optical disc is the top solution of a 15 cm x 25 cm recycled paper disc. Technology does not progress, but returns naturally and follows the providence provided by the Creator.


The current 1920 × 1080 high-definition display device has a problem. It is MPEG. Even in H.264, the necessary amount of information is insufficient, so the image quality lacks naturalness. Since the EBD has a recording capacity 1.6 times that of the BD, a part of 60% of the EBD can be applied to the increased amount of information reviewed while maintaining the compatibility of the DCT.

On the other hand, a stereoscopic display device that does not require wearing glasses or fixing a viewpoint is known in another application. This can supply 200 inches to the market for 100,000 yen. In this case, the information given to the left and right eyes is not doubled to 50 GB, but instead of being displayed alternately on the left and right to fit in 25 GB, it is stored in EBD as 25 GB + 15 GB = 40 GB plus 15 GB for left and right parallax. It is what In addition, the conventional two speakers, the audio system of 5-1, the binaural system using headphones, and Dolby Surround lacked a true new sense of realism. This problem has already been solved and a natural solution has already been filed.

<BD / EBD / SBD / NBD>
In the above-described image display device for which the principle design of the manufacturing method has already been completed, the manufacturing cost does not depend on the number of pixels or the screen size, and is necessarily a wall-mounted roll paper. The standard size of the diagonal is 200 inches, and the wall illumination has an efficiency of 40% with respect to the illumination efficiency of 3% of incandescent bulb and 15% of FL tube, and the lifetime is about 100 years.

Background that is 40GB request most strongly EBD having a storage capacity of is that it was standing prospect to the realization of the intrinsic three-dimensional TV, the ground resolution of the three-dimensional display, point of view fixed system (NTT or Sanyo) or glasses system ( LCD two glasses or Matsushita system). Aerial solution is a viewpoint tracking method. The true heavenly solution is different from these. The requirement for true stereoscopic TV is the correspondence with the optical disc shown in FIG.

1) A single screen 2) Auxiliary light such as a hologram method should not be used 3) No need to wear glasses 4) A viewing point need not be fixed 5) Multiple viewing 6) A 3D image that appears in front of the screen can be touched with a hand and a GUI can be used as a handle.

It is. For this reason, pushing the 50 GB portion of the left eye imaging data and the right eye imaging data into 25 GB, which is the same as the flat display, blasphemes the true stereoscopic TV. It is a blasphemy against science to leave it at 50 GB. In the end, it is desirable to effectively use 40 GB in the 40 GB EBD, as shown in FIG. 73, together with the interpolation of lack of smoothness image quality information of Hivision and the data embedding of the true 3D sound field.

In the top 3D sound image, 5.1W of 10W + 10W is changed to an intrinsic 3D individual sound field of 100mW + 100mW, and the sound is separated between families. Directivity is not a direction but a single point. In this case, since the viewer is tracked by the RFID marker, it can be combined with a viewpoint tracking type aerial solution stereoscopic television. From the standpoint of maintaining the global environment, these daily necessities AV products are in the form shown in FIG. 74, and in the 20th century type, less than 1/10 of the power consumption and less than 1/5 of the manufacturing cost, ) Can't survive if it doesn't increase more than 5 times.

<List of optical components>
FIG. 75 shows the optical component configurations of the classic format, modern format, and CSOP. In the classical format, 10 points were required for the OP only for Bluray, except for focus control focus VCM, tracking coil, and skew coil. Is 1 point.

<Resolution not determined by wavelength and NA>
The reason why BD is called the classic solution of optical disks is because there is only a shallow strategy that does not change, involving short wavelengths, NA, and the movie industry. First of all, this paper is based on a conventional method that has never been used to trace one track with a detector that is as thin as a sapphire needle when playing an optical disc. , Illuminating a small area containing several tracks and bringing in the conflicting concept of image processing on the PD surface for signal processing.

In this regard, it is determined which is the finer detection. The conclusion is that it is advantageous to determine the resolution on the PD side. Even if the lens is NA = 0.85, if NA = 0.85 is used up with uniform distribution, if irradiation is cosine distribution and vertical and horizontal elliptical radiation is used, it is effective at NA = 0.65. Will do. As reflected in this, if the depth of the active layer is about 250 μm, the NA becomes small due to the aperture coefficient. WxH opening is also added to this. In addition to this, the spot becomes larger due to the phase dispersion of ΔWxΔHWxΔL / n. These spot expansion factors can be avoided by reducing b / a.

On the other hand, when the resolution is determined by the PD, the size of the PD can be reduced to the limit at which the S / N is determined by the light amount, and the NA limit can be made to have a uniform distribution because the irradiation is sprue over. . Therefore, the PD resolution method is finer than the LD resolution method by about 30% in both the X direction and the Y direction. This often appears in simulation results.

EBD uses the same wavelength of 405 nm and requires 1.2 times the resolution in the circulation direction and 1.33 times the resolution in the inter-track direction compared to BD. It is. As for the resolution between tracks, EBD originally has the same margin as that of BD, and inter-track interference due to the PD array is corrected.

It can be said that the stability in mass production of 40 GB EBD and 25 GB BD is substantially the same. Both 40 GB and 25 GB are not very different from the viewpoint of recording capacity. This is because the true stereoscopic TV never requires an increase in recording capacity. In a 3D TV, if a capacity of 25 GB is required on the XY plane, a 3D TV in which 8 sheets are arranged before and after the XY-Z needs a recording capacity of 200 GB, or a recording capacity of 50 GB in LR. The 3D TV defined by engineers is a fake. This is because the three-dimensional view that a person sees has only two-dimensional perspective and binocular parallax, and the amount of information has not increased.

The BD has already been in a form in which the thickness of the protective layer is changed from 0.6 mm of DVD to 0.1 mm at a stroke, and the pride and scratch resistance of the disc is abandoned and stored in the caddy. In the future, however, we must refrain from pursuing the short wavelength and high density by hindering the practicality of consumers. The 21st century product should be the first to be robust and easy to use.

<Remote focus diagnosis / treatment device>
The optical pickup can be used for pathological purposes. There are two ways to use lasers.

1) Focus on narrow parallel beams such as laser processing beams, laser pointers, and laser scalpels. This destroys everything on the line that reaches the target equally.
2) The phase is concentrated only at one point in the depth as in OP. This has no effect while concentrating on the target.

Mobile radio waves are spread in the air, but mobile phones are concentrated in the ears. It is humorous for someone who is afraid of leaking radio waves from a microwave to talk on a mobile phone.

The laser pointer is an edge-emitting radiation sprayed in the shape of a fan. On the other hand, in OP, a large objective lens is attached to the edge emission radiation at a distant position and converged again by the target. In the wavelength region of electromagnetic waves, the wavelength region of light, the wavelength region of X-rays, or the wavelength region of elementary particle beams, it is overwhelmingly less damaging to other tissues when converged to a pinpoint at a three-dimensional point. Laser scalpel is a laparotomy, but the OP method can be performed without laparotomy from outside the body. Conventionally, all were considered as parallel beams. This is due to the snake side. Various types of radiation therapy and laser scalpels.

On the other hand, on the other diagnostic side, 1) X-ray imaging, 2) ultrasonic diagnosis, 3) CT scan, 4) MRI imaging, and the like are spray types on the other side. It is inadvertent that the treatment side is not spray-type. Isn't it the responsibility to have inadvertently created the fiction of photons about 100 years ago?

First of all, it is important to make the diagnosis side and the treatment side common by using a spray type that can pinpoint the target on both the diagnosis side and the treatment side. In the case of OP, when recording, the target is focused on the pinpoint and irradiated with light, and when reproducing, the target image is detected at the pinpoint with PD. In this case, it is extremely important that recording and reproduction are performed by the same optical system. In OP, light is dispersed so that scratches on the surface of the disk are not affected. Similarly, medical diagnosis and treatment are not affected by the tissue between the affected area and the lens.

When the OP method is used for pathological diagnosis / procedure, it is meaningless to remove it 2 days after diagnosis if it can be clearly erased by electromagnetic response from the marker or direct response from the lesion. When a target for diagnosis is identified with a resolution of several microns in human tissue, it should be erased within a few uS before the body moves with the exact same optical system.

The main cause of the rising medical costs in each country and depopulated medical problems in villages is expensive medical equipment such as MRI. The OP-type diagnostic / surgical instrument is about the size of a portable terminal, and under the supervision of a doctor, you can continue to diagnose and perform at home. This is because 3D scanning of the entire human tissue with a resolution of several tens of microns is not possible at a hospital.

Cancer is an incurable disease as opposed to AIDS, whose onset can be suppressed with drugs. In tens of thousands of years since departure in Africa, human beings were able to adapt to the extreme depigmented race and the dense melanin race just below the equator. This is because they have made the choices for Cancer was a necessity there. So don't fight cancer. What humans can do is to pass cancer and survive.

Any number of cancers can be made. Any number of transitions may be made. At a stage of several tens of microns, diagnosis is made from one end, cells are broken from the other end, and DNA is made naked. If it is that size, the tissue will fix the unburned residue, so it is not necessary to open and remove it.

It is the current distribution of the CSOP that corrects the refractive index (dielectric constant) distribution of the tissue of the human body to compensate for the astigmatism of the beam at the location where the light beam spreads. In order to determine this current distribution, it is only necessary to look at an image from a site for each change of the active layer, whether the irradiation light can be reduced. The human body tissue is opaque in visible light / ultraviolet, but is transmitted in radio frequencies up to millimeter waves, infrared, X-rays, and MRI frequencies. If the spot can be narrowed down to 20 μm, when NA = 0.7, the intensity of the electromagnetic wave / light is 1 / 50,000 on the optical axis 1 cm away from the affected area, and other tissues of the human body are not affected. Even cancer in blood vessels can be removed.

The medical OP can be driven by a dry cell. The scan time for diagnosis and treatment per cubic centimeter (about 1 gram) is 125 seconds. It takes 10 million seconds for a person weighing 80 kg to scan the entire body. Since one day is 80,000 seconds, it takes about 200 days if automatic scanning is not performed while sleeping. Since this instrument can be marketed for about 10,000 yen, it is important to do it at home.

The diagnostic data of the points scanned from all directions of the body is accumulated with reference to the background organ, so that no scan leakage occurs.

The key point is whether it is possible to distinguish the electromagnetic response of the site with something like a PET marker, or whether the wavelength at which the cancer has an electromagnetic response different from that of normal tissue can be found. Otherwise, it is an indirect method in which the results of the scan are accumulated and image diagnosis is performed in a large chunk, the whole is burned out, and then the burned-out tissue is sucked from the endoscope hole. This is a ground solution.

The current breakage of DNA by radiation causes a base change of DNA at the periphery and creates a new cancer. This is a hell solution. The only solution is to live with cancer, destroy cells thermally at a stage of tens of um, and take away the opportunity for DNA growth.

If the current response of the diagnosis can be distinguished, cancer, which is an incurable disease, will remain incurable, but few will die from cancer, just as those who die from tuberculosis will not die after the war. FIG. 76 shows the OP mechanism. If a small cancer is always found, everyone can be humble. With its humility and unwavering tolerance, the chance of developing small cancers is greatly reduced. There is no limit to caring about people.

FIG. 77 is a simulation of what spots can be formed in the body from outside the body. It is the same as an optical disc that is not affected by dirt up to the pit surface. Here, understanding is divided into two. After all, light is a flow of energy, and if it is accumulated along the way, it may be affected even if there is a threshold. That is the difference from particles and waves. Light and electromagnetic waves are not particles or waves. It is just a remote action. The physics of the 21st century has already solved this, and it is irrelevant if there is no phase concentration between the affected area and the OP.

<Results of new OP products>
FIG. 78 shows the results of the new OP product. Their characteristics are

1) 40 GB can be read and written with BD compatibility with EBD, and stereoscopic image high-definition information can be recorded.
2) The structure of the conventional OP is innovatively simplified in modern format, modern format, CSOP, etc.
3) 3 Way OP can be easily manufactured.

That's it.

<Block recording / playback of SBD optical disc and NBD optical disc>
There are SBD (Super Blu-ray Disc) and NBD (Natural Blu-ray Disc) as top solutions for optical discs using the same wavelength of 405 nm. Two solutions exist because there are rotating disks and non-rotating sheets. SBD and NBD are recorded / reproduced in block units even on an optical disc so that the barcode has 1D and 2D, and 2D can read more data in an instant. As shown in FIG. 79, there is a 12 × 12 pit arrangement in one Block. As for the size of the Block, the SBD has a size of 3.6 um × 3.6 um, the NBD has a size of 4.8 um × 4.8 um, and has a guide groove at the block boundary. .

<Recording capacity of SBD optical disc and NBD optical disc>
As shown in FIG. 80, one pit has a depth of 8 bits in the 12 × 12 pit arrangement. The pit height is 4 bits and 2 bits deep. There are 8 positions in the X direction and a depth of 3 bits. There are 8 positions in the Y direction and a depth of 3 bits. Combine these 3bit + 3bit + 2bit = 8bit
It becomes.

Since the 120 mm diameter rigid disk has an effective area of 9000 mm 2, it has a recording capacity of just 100 GB. A sheet with an effective area of 16 cm × 25 cm has a recording capacity of just 250 GB. This recording / reproduction is performed in MPEG2 / 4, H.264. It is made in the NPEG domain, which is a celestial solution, with respect to H.264 ground solutions, and can record and play SV (Supervision) and NV (Natural Vision) intrinsic stereoscopic images for 2 hours. These standards are not a Man-Made such as MPEG but remain natural.

Under the same optical conditions, we should note that the difference is four times wider because BD is 25 GB while SBD is 100 GB. The battle between 15GB HD-DVD and 25GB BD is an evil brought about by the industrial revolution. In the 21st century, we must look forward to seeing what the Creator has prepared, not relating to such things on the earth. The main factor that makes the difference between 25 GB and 100 GB depends on whether to use a Man-Made thing called EFM modulation / demodulation or to use a natural-lookup-table. The Lookup-Table can be recognized for the first time in the group (EFM is the absolute value of each, and the Lookup-Table is a relative value, and even if it interferes, it is determined including it). Modulation / demodulation judges things on a uniform basis, but Lookup-Table is a concept that allows anything and looks at anything small.

It is noise that we confront, not the rotation irregularity that we have invited. As the Lord who is cancerous and able to adapt, the noise is the screaming vibration of 10 80th proton-electron pairs in the Big Bang universe. When you decide to live with it, the natural rules of 100GB and 250GB will be ours. Do not hate the noise.

Since light is recorded / reproduced in a non-contact manner, the natural rule is 100 GB at a wavelength of 405 nm. Since the hard disk is in contact, 250 GB can be recorded / reproduced even at a wavelength of 1,000,000 nm. Therefore, it is natural law not to compete. The Creator prepares physical principles to coexist.

As shown in FIG. 81, the 12 point light source arrays are composed of edge-emitting LDs. Since the end surface light emitting LD has a short reciprocation length, the electromagnetic field easily leaks to the side, and phase synchronization with adjacent channels is easy. In addition, since the channel length is short, the stability of the light reciprocating mode is fast, and modulation is possible at a high frequency as compared with edge emission. Each of the twelve active layers # 1 to # 12 looks like a point light source according to the principle shown in FIG. Each main active layer has sub-active layers above and below, and when a current exceeding the threshold current is passed to either of the main active layers, it enters an LD mode, and is phase-locked by electromagnetic coupling with the main active layer. If phase synchronization occurs, the main active layer and the sub-active layer constitute a single point light source based on the principle shown in FIG. 10 and its position is swung up and down by current distribution and phase difference. This is the PPM in the Y direction.

PPM in the X direction is performed with a time difference in which the disk rotates.

During reproduction, PPM and PDM are detected by the micro PD arrays # 1 to # 12 as shown in FIG.

The conventional optical disc has a problem of compatibility between the disc and the OP, and the disc is required to conform to the standard and the OP conforms to the standard. Flexibility does not exist between them. In order to remove this serious problem, the SBD writes a Sample signal to the TOC, and uses it as a Lookup-Table, and the analog quantity array data detected by the PD is the most similar among the analog quantity arrays on the Lookup-Table. The problem of compatibility between the disc and the OP is eliminated. This Lookup-Table includes 12 × 12 intra-block interference. There is a sufficient guide band because it does not include inter-Block interference. Compared with the method of EFM and slicing the signal with an eye pattern, this allows overwhelmingly deep modulation and eliminates the compatibility problem. Therefore, it has a depth of 8 bits per spot (3 + 3 + 2).

Further, compared to the conventional single-track system, it is not affected by disc rotation irregularities and clock jitter.

FIG. 84 shows the relationship between the transmittance of the end face and the delay time of the light intensity modulation of the LD. The Q value of the LD resonance must be selected according to the response speed. Do not choose operating points that are far from the optimal value of the system due to false concepts such as spatial coherency, temporal coherency or parallel beams.

In NBD, a 12x12 pit in a 48 um x 48 um block is read and written by electromagnetic levitation, attitude control, wireless signal transmission / reception, and wireless power transmission CSOP. The CSOP is a circular or square array, and in the case of a circular shape, NA = 0.8. NA of BD = 0.85 corresponds to NA = 0.6 in CSOP. The CSOP changes the current distribution of the light emitting element array and can electronically scan the phase concentrated spot in the block on the XY plane of image formation at high speed.

FIG. 86 shows an example of a classical format of SBD recording / reproduction.

FIG. 87 shows a CSOP for SBD / NBD. The position of the quadrant PD, the diameter of the CSOP needle, the focal depth, and the electronic tracking characteristics are shown.

During recording, 12 × 12 pit PPM / PDM writing is performed by this deflection scanning. At the time of reproduction, the PPM and the PDM can be detected by detecting the return light with the PD arranged in the center of the surface emitting array.

Among the electromagnetic levitation and attitude control, in the static magnetic method, as shown in FIGS. 88 and 89, the CSOP chip with the back surface magnetized is levitated on the NBD sheet to be stationary, and it is magnetic three-dimensional to fly freely It is confined in the potential, and its posture is fixed and moved. The NBD CSOP has a surface emitting LD array chip mounted on a CMOS silicon IC having PDs at four corners. Place this on a quadrupole magnetized Arabian carpet.

If the NS poles are placed facing each other in a plane-arranged quadrupole magnetic field as shown in FIG. 90, the optical axes of the CSOP are stabilized by being pulled by each other, and the orientation of the CSOP is also stabilized. The coordinate position is also stable. However, if the XY coordinate position deviates from the center position, it will deviate in that direction.

Next, as shown in FIG. 91, when the NS poles are placed opposite to each other in a vertically disposed quadrupole magnetic field, the optical axes of the CSOP are stabilized by being pulled together, and the orientation of the CSOP is also stabilized. -Y coordinate position is stable. However, if the Z coordinate position is deviated once, it will be pulled by one of the magnetic poles.

Therefore, as shown in FIG. 92, a combination of both is formed to form a magnetic potential well in which three of the XYZ coordinate position, orientation, and optical axis are stable. In practice, the lower quadrupole of the upper and lower arrangement is omitted. This magnetic potential well can be quickly moved to any XY coordinate position by switching the DC coil array on both sides and changing the balance of the quadrupole. This can realize the three-dimensional confinement that the tokamak fusion design could not be achieved.

An OEIC having a PD has an on-chip coil, receives power from an upper surface coil by electromagnetic coupling, and most of the power is consumed by a surface emitting LD array. The write signal and control signal amplitude or phase modulate the power carrier, and the read signal phase or amplitude modulates the backscatter. FIG. 93 shows the CSOP control method. A mode of driving the CSOP is referred to as RF-Identified-Flying-Object.

From the viewpoint of global environmental conservation, the total thickness of 1.2 mm of the optical disk is a waste of resources, is a waste problem, and is incinerated and becomes an air pollution problem. This thickness is required for a rotary disk to suppress the vertical movement of the disk. Also, the thickness of the protective layer is necessary to reduce the influence of scratches. If there is no loss of writing and rewriting is repeated, the waste of resources is halved.

It is clear what humanity should ultimately do with optical discs.

1. 1. Stop the rotating disk system and eliminate the problems of vertical movement and decentering. The board should be wood paper or cone paper.
3. Use only plastic with a protective layer of 0.1 mm.
4). Caddy is not used, scratch data is acquired online and complemented

This is the definition of NBD.

<Electronic control by CSOP>
The purpose of electronic control with a surface emitting LD configured for CSOP is

1) Spots need to be deflected electronically with SBD and NBD 2) Focus, tracking, and skew control are performed electronically with CSOP 3) Deflection and convergence are required for rendering of flat and stereoscopic images with CSOP

In doing this, the CSOP must first fully understand that it does not have a lens and forms an image. What disturbs understanding is Newton-Einstein-Hebide-Heisenberg pseudophysics, contaminated by 20th century physics. The surface light emission for CSOP has a completely different mechanism from the VCSEL developed without purpose, in which the surface light emission can be achieved if the end surface light emission can be performed without the purpose like the conventional surface light emission. Accordingly, the operating principle is completely different. The light condensing function that replaces the lens is obtained by arranging the phase-synchronized surface emitting LD array and causing phase concentration at the condensing point.

FIG. 94 is a dimensional diagram of a CSOP for a wavelength of 405 nm. Since it is extremely lightweight at 2.5 mg, it can be driven at an operating distance of about 0.5 mm. NA is 0.8. In the case of this CSOP, focus and tracking are performed by an electromagnetic coil, and only skew adjustment is performed electronically. The VCSEL has an active layer of ˜50 nm and the reflective layer is a tens of layers of upper and lower quarter-wave reflectors, which simply simulates an edge-emitting LD, whereas the active layer is as thick as several tens of um. The upper and lower Al electrodes are resonant reflectors. VCSELs resonate at a single wavelength because of their short reciprocation length, but VCSELs have multiple resonance wavelengths as with edge emission. The VCSEL does not enter the LD mode unless the light emitting surface is drawn out in a circular shape and light is extracted from the surface and the amount of light reciprocating with respect to the extracted light is not more than 99 times. On the other hand, in CSOP, light is emitted obliquely toward the condensing point on the disk surface, so that it is not necessary to pull out the upper surface electrode, and it merely serves as a reciprocating reflector. Since CSOP has an overwhelmingly larger active layer volume than VCSEL, it easily exceeds the current threshold and enters the LD mode.

In CSOP, the entire LD array is electromagnetically coupled and phase-synchronized. The resonance is not only the resonance of the reciprocating light in each active layer, but the optical path difference from the light emitting point to the disk surface is always an integral multiple of the wavelength to form a spot. The definition of light disturbance does not hold. The phase is synchronized with the return light. The electronic adjustment of the skew is omitted because the display is complicated.

The spot shape of CSOP is shown in FIG. The reason why it is formed is shown in Equation 36. FIG. 96 shows a spot shape when a 3.6 μm (9 wavelength range) angle is scanned diagonally by SBD.

<Basic principle of phase concentration>
The CSOP can cause phase concentration at one point (X, Y, Z> 0) without any restriction in the half space in front of it. Moreover, it is possible to cause phase concentration at a plurality of points simultaneously by superimposing them. There is a great principle here that can be called the providence of the Creator. As shown in FIG. 97, there are two main active layers A and B, and there are eight sub-active layers around each main active layer. If the light emission from the two active layers A and B is phase-synchronized, the plane in which the points A and B2 are mirror images is a place where the phase is concentrated in the space. When a large number of such light emitting points are gathered, normally there is only one half-space or one phase concentration point. This is an entity that was understood as a law of conservation of energy in the 19th century, and an entity that was distorted by Oliver snakeside. As shown in the example in the figure, out of the nine points, four points that form the four corners including the main active layer are selected, and the current distribution is selected within the range in which the LD resonance is maintained, so that the total amount of light emission is 1. If this is the case, this LD array can cause phase concentration at any location in the half space. The function does not depend on the interval between the nine points, and may be a small interval or a large interval. If the interval is 1/4 of the wavelength, the aperture gain when the weighting is set to 50%: 50% is 0.707 when 1 is set to 100%: 0%. Then, if we say that the distance between the main active layer and the sub active layer should be reduced, the providence of the creator is interposed there.

That is, the resolution of the phase concentration point in the space is determined by λ / L. On the other hand, it is also determined by the dimension D of the array composed of a large number of resolution LDs. L may be determined in consideration of both.

In general, the LD light emission amounts of four equal main active layers are weighted instead of the unit of eight sub-active layers around the main active layer.

Compared to the case where the angle formed by the scanning points in the three-dimensional half space is large, as in the case of flat / stereo TV using CSOP, when using CSOP for reading / writing optical discs, only limited spot control is performed. A simple LD array emission point array and its drive current control are used.

<Multi-layer simultaneous recording and playback>
As shown in FIG. 98, an independent spot can be formed at a plurality of depths of focus simultaneously with a CSOP having a multi-focus ring active layer arrangement LD array configuration. It can be performed. The biggest difference between multi-layer simultaneous recording and multi-layer sequential recording is that the former writes all layers with a single clock, while the latter has no relation to the clocks of each layer. This avoids aliasing when reading at the same time, and can compensate for interlayer interference.

Simultaneous reading of the multi-layered pit row is performed by detecting reflected light obtained by modulating the irradiation light with multiple frequencies with a four-divided PD and then separating with a multi-frequency BPF.

<Effect of reflection Al layer on radiation>
Considering that only 1% of light is emitted from the reflective film having a reflectivity of 99% in the state where the light emission of the LD reciprocates and resonates in the active layer, nothing is quantitatively analyzed. Heisenberg is like an uncertain principle. This is not a science but a mere thoughtless state. It is assumed that the reflective film does not spread over a wide area but covers only the cross section of the active layer. It is assumed that the resonance still exceeds the current threshold. The radiation of the active layer itself has already been analyzed and agrees very well with the actual measured values as shown in FIG.

So how does the radiation of the re-radiated current that flows in the aluminum reflective film add to this? In conclusion, it remains as shown in Equation 6 and FIG. 16, and there is no need to worry that the aluminum reflector is blocking forward radiation.

FIG. 99 compares the structure of a conventional edge-emitting LD with the CSOP aluminum layer reflecting surface-emitting LD. In the former, a total reflection film is coated on the cracked surface. The latter simply has an aluminum layer electrode for wiring. Next, it can be seen that the round-trip reflected light is a combination of the two waves shown above and below. This is the sum of a forward wave with a length L of the active layer and one that has a light source on two surfaces and propagation is parallel rays. This is because the near field just before the aluminum layer is zero in the central axis, but the far field has the radiation characteristics shown in FIG. 16, and the aluminum reflector does not prevent radiation.

Those who developed surface-emitting LDs were confused not with radiation characteristics but with resonance conditions and radiation characteristics. In the case of edge emission, this discussion is not valid because the entire cross section of the chip, not only the active layer cross section, is subjected to total reflection treatment. In addition, OP radiation is absolutely necessary to irradiate the entire objective lens in order to maintain the NA value, and parallel rays do not make any use, but those who have developed surface emitting LDs (VCSELs) Since it was not accepted and only the optical input to Fiber was used, there was an error because it was only possible to use parallel rays. Even in practice, the input to Fiber requires fan-shaped (spray) radiation. After all, the aluminum on the radiating surface gets in the way, so it became a chain of mistakes to create several tens of layers of Bragg reflecting surfaces.

<CSOP concentration range>
When the CSOP is used in a direct view / projection type active layer projector, the characteristic is shown in FIG. 100 as a product of the radiation characteristic shown in FIG. It becomes like this. Since the array factor is always 1 when all active layers are phase-concentrated, the far field in FIG. 16 is defined as a viewing angle as defined by an LCD display.

In order to widen the radiation angle with the surface emitting LD, L may be shortened. Even if the length L of the active layer is short, the single spectrum or the optical path coherence can be maintained if the distance between the aluminum reflectors is long. In CSOP projectors, the rear aluminum reflector is separated from the LD chip to maintain optical path coherence. The length of the active layer is independent of the electric field strength that results in stimulated emission. The electric field strength for stimulated emission is related to the reflectivity of the aluminum layer. When the image brightness of the 50-inch CSOP stereoscopic display is sufficient, it is not necessary to give the electric field strength until the lattice structure of the active layer is broken. It is ridiculous that the transmittance of the optical axis direction minus 1 is radiation (although all textbooks on optics in the 20th century are described so), if there is no mistake, it is brighter than an LCD display, 100 It can be operated with an LD having a lifetime of 10,000 hours.

This consideration is important for the view angle of the 20th century. It is contradictory to widen the viewing angle and attach a filter that narrows the viewing angle. The CSOP projector can electronically give an optimal front view to the individual viewer. Appreciating TV is the best way to avoid bothering the sound field and video.

<Surface emitting LD and polarization plane>
The edge-emitting LDs usually have the same plane of polarization. Since the surface emitting LD has a short active layer length and often has a circular cross section, the plane of polarization is not single. This is however no problem in terms of coherence.

<High-speed, small-range focus servo using CSOP>
The conventional electromagnetic focus servo using a voice coil and permanent magnet can correct the focus error in the middle range. The only unit that exists in the range from the particle to the Big Bang inflating sphere is three-dimensional meters and seconds. I was in charge of responding. There was no mechanism in charge of high speed and small area, and passive measures were taken to smooth the disc pit surface and avoid scratches as much as possible.

Switching the focal length from F1 to F2 in CSOP is very simple. What is necessary is just to interpolate with an electric current between the active layer ring of CSOP which produces | generates F1, and the active layer ring of CSOP which produces F2. The Creator's skill is simple beyond imagination and is more elaborate than what humans might create 10,000 years later on their own. The person insists that the two-screen 3D television of the NTT system uses the human illusion, which is an illusion. That is the basic principle that makes up the real world. Sine waves (light and electromagnetic waves are not waves but only orbital electrons are moving in a circular motion).

FIG. 101 shows a structure of a double active layer ring for variable focus. The relationship between the aluminum electrode for reciprocal resonance on the front surface and the radiation is as analyzed in <0063>. Considering this, the active layers of the double rings are interleaved.

FIG. 102 shows a comparison of spot shapes with focal lengths F1 = 0.6 mm / NA = 0.8 and F2 = 0.7 mm / NA = 0.75. It can be seen that when NA = 0.8, the spot is slightly thinner and the intensity is slightly lower. When the electronic focus servo is used, since the spot diameter and the side lobe change, the coefficient sequence for crosstalk compensation must be changed accordingly. However, if F2 is extended to the outer ring so that NA becomes constant, the spot shape does not change.

FIG. 103 shows the depth of focus at F1 = 0.50 mm on the XZ plane.

<High speed, small range tracking servo by CSOP>
As shown in FIG. 104, by selecting the current distribution of the phase-synchronized LD array, for example, with a CSOP having an array size of 1.6 mmφ and a focal length of 0.5 mm, a spot can be obtained in the range of ± 100 tracks (± 32 μm) of BD The spot shape does not change significantly. This tracking is fast because the CSOP and the disk are fixed electronic and do not involve mass. However, tracking is already indispensable and indispensable for the low and high speeds and the entire range of the sled motor, and the middle and middle ranges of the electromagnetic coil. In this application, the electronic tracking of CSOP is not used.

Nevertheless, CSOP has an overwhelming advantage in tracking servo because the inertial mass is about 2.5 mg, so that the response speed of the electromagnetic coil becomes medium to high.

<High speed and small range skew servo by CSOP>
Skew error is an asymmetry component of astigmatism, which is the astigmatism that remains after the tracking servo follows the movement of the spot and the focus service follows the change in focal length, and its quantitative definition is established. Is not. Here, when NA = 0.8, the maximum incident angle is 53.1 degrees, which is defined by the optical path difference of the outermost angle when the optical path differences are combined at an incident angle of 25 degrees. As shown in FIG. 105, skew servo is electronically performed in any case in CSOP.

<Share of CSOP and medium-speed / medium-range electromagnetic servo>
Rather than electronically performing all of the high speed and small range of focus servo, tracking servo, and skew servo with CSOP, the emphasis is on being small and light by surpassing the advantages of CSOP. It can be said that an optimum combination in BD / EBD / SBD is that an unprecedented high speed / medium range can be achieved and only the more complicated skew servo of the mechanism is replaced with electronic adjustment. On the other hand, in NBD, it is appropriate to perform floating attitude control for all of the high speed and large range of focus servo, tracking servo, and skew servo.

<Minimum spot forming function of CSOP for optical disc>
When CSOP is used in an optical disc, it has a surprising nature as a natural rule. That is, it has a self-alignment function that automatically forms the smallest spot automatically by phase synchronization of the entire LD array. The CSOP is first phase-synchronized in the LD array chip by electromagnetic coupling between the active layers. The focus is defined to be just focused at the pit, that is, the optical path from the light emitting point of each active layer to the pit surface has the same excess length as an integral multiple of the wavelength. Even if the light path is reflected by the mirror surface portion of the pit surface as it is and the reverse optical path is followed, the optical path is the same in that it has the same extra length as an integral multiple of the wavelength. Since the phase is reversed by 180 degrees in reflection, the same remainder satisfies the resonance condition at any of 1/4, 1/2, and 3/4 of the wavelength. From this point of view, CSOP is a single large PLL system (originally PLL is not phase-locked and the frequency is locked without cycle slip, but a steady phase error is always necessary to absorb the frequency difference. It is a natural law, and PLL is a major mistake of the first name named phase-locked), and all active layers that are resonators are wavelength-synchronized without cycle slip, and even to the phase due to electromagnetic coupling between adjacent active layers This is a parallel operation double loop in which phase synchronization with strong loop gain by return light is added to uniform wavelength synchronization. It is extremely easy to replace this with an electric circuit and perform a simulation with SPICE or MATLAB, and an accurate analysis and optimization is performed.

The entire active layer double loop functions as an autofocus having a relatively wide tracking range in the mirror surface portion. In the pit area, the area around the optical axis of the reflected light is attenuated, and the average optical path is shortened by a quarter wavelength (when the pit height is a quarter wavelength) by reciprocation, but there is no fundamental influence on the autofocus operation. . In order to keep the CSOP and the disc within the range where autofocus follows, the light amount of A + B + C + D obtained by the 4-division PD is detected by zero crossing.

There is no effect on tracking. Skew is automatically corrected. The principle that a simple spot is automatically formed with a simple structure to write is that the Creator gives us +1 and -1 Adam and Eva, and as a natural reason that we can do that, we just human Do not let a godly person stay. FIG. 106 shows a form of the minimum spot forming function.

<Drawing a stereoscopic image by CSOP>
The image data recorded / reproduced on the optical disc BD / EBD / SBD / NBD by the CSOP1 (chip size optical pickup) is displayed as a stereoscopic image by the CSOP2 (chip size optical projector). However, since BluRay is a planar image standard, the disc format is EBD / SBD / NBD even if the wavelength of light used for recording / reproduction is the same 405 nm. As shown in FIG. 116, the wavelengths of the RGB primary colors LD used for stereoscopic image display are 650 nm, 530 nm, and 450 nm. Such a wide band gap width does not exist for the visibility of the retina and the spread of the spectrum of LED emission. Visibility and LED light emission also have several cycles of electron orbit transition time called wave packet, so when measured with a spectroscope, it looks like this wavelength intensity distribution. There are few opticians who understand this correctly, so here we will reaffirm the correct understanding.

As shown in FIG. 107, the three-plate RGB LD array chip has one circular array radiator for a 1920 × 1080 HV, four for a 3840 × 2160 SV, and 16 for a 7680 × 4320 NV. The resolution of the deflection of the array radiator is approximately expressed by a numerical value obtained by dividing the diameter of the array circle by the wavelength of light. If the diameter of the array is 2.2 mm, the resolution is 4000, and the horizontal resolution of HV is 1920. Is double. That is, SV is four parallel HVs, and NV is 16 parallel HVs. The band of the HV video signal is 100 MHz, and SV and NV are also divided into 4 and 16, respectively.

3D image display method

1) Using the parallax of the left and right eyes (pseudo stereoscopic TV)
2) Placing an equivalent luminous point in a three-dimensional rectangular parallelepiped (true stereoscopic TV)

There are two types. First, in 2), even if the eyes of a horizontal row are arranged vertically, the stereoscopic image remains as it is, and the stereoscopic image and the human are related by 3D-GUI, and a plurality of viewers separate one. However, in 1), the eye alignment is kept horizontal, and the viewer cannot select the viewing angle regardless of the 3D-GUI.

A complex stereo image is required to be captured by a three-plate, multiple-type stereo camera corresponding to the method of 1), and the information that has doubled there is correlated and compressed as shown in FIG. The amount of information can be increased by about 50%. The imaging method of the method 2) is completely different from this, and as shown in FIG. 114, imaging is performed with a three-panel single plane / stereoscopic camera, but a depth index is automatically added for each pixel area (texture), The amount hardly increases from the planar image. Photographers can shoot stereoscopic images in exactly the same procedure as before. 2) is suitable for games and computer graphics. Reality 2) is overwhelmingly suitable.

Displaying a stereoscopic image is expensive because 1) is performed with 2 sets of 3 plates in XY coordinates, but 2) is inexpensive because the image is formed with 1 set of 3 plates in XYZ coordinates. 2) has long been realized by holography as a still image or a quasi-movie, but holography has no possibility of watching TV. In holography, laser light is divided into two paths as shown in FIG. 108, and when an object is placed on one of the paths, the phase of the laser light that has been re-radiated from each part of the object to the laser light that hits the object is inherited. Therefore, phase concentration occurs when the two optical paths meet again, so that the object moves and forms a three-dimensional image there. Although it is very primitive as an optical principle, re-emitted light from an object is Fourier-transformed, and the procedure for recording this as a moving image is complicated and not practical.

The only realization of 2) is that two images are projected on the front and back as shown in FIG. 110 and two images are projected. When the two images overlap, the ratio of the brightness of the front and back images Is recognizing that it is in the middle place. This means that the front image must be projected in a perspective smaller than the back image, and the front screen must be translucent. The viewing point is fixed at one point.

The stereo method of 1) started with a movie popping out in the 1950s, and every method was tried, but the left and right parallax is part of human 3D recognition. For example, even if a single eye moves up and down, it is 3D It is also related to the three-dimensional sense to focus on. The stereo system is not only expensive, but requires a larger amount of information and does not match the rendering of computer or game graphics, so it cannot be considered worth further consideration. Before the stereoscopic display, the display device must have sufficient qualities.

<Redefinition of stereoscopic images>
The reality of the 20th century electronics industry is that the realization of stereoscopic images has been extremely difficult for the electronics industry, so the past viewpoint has shifted to pseudo-stereoscopic images, and the definition of stereoscopic image display has become unclear. Nevertheless, since it is difficult to commercialize the resolution of 7680 × 4320 for the time being, the development theme remains only for stereoscopic images. Also, in the game, CG world, and GUI, only a two-dimensional expression with a three-dimensional intention was possible.

Naturally, a stereoscopic image is the reproduction and expression of a natural image as it is. However, it cannot give a real molecular structure to an image, and it cannot give life to a living thing. It is a 3D display where texture is pasted on the surface of an object, or a fish swimming three-dimensionally in three-dimensional translucent water like an aquarium tank. Considering a little, it can be seen that this three-dimensional state cannot be called a stereoscopic TV unless it is reproduced in front of the eyes.

Sound fields, atmospheres, and scents are indispensable for reproducing nature as it is, but the definition of stereoscopic images includes sound fields and excludes atmospheres and scents.

On the other hand, the retina of the human eye is two-dimensional. In order to reproduce this state as completely as possible, it can be seen that it is not sufficient to have an object that exists in three dimensions as an image as it is. Notice that the image must be recorded in two dimensions, not three dimensions.

The binocular parallax method that has been performed without exception as an attempt to display stereoscopic images other than holography so far is different from two-dimensional recording. Since this binocular parallax method uses not two single-dimensional image recording but two two-dimensional image recording, it can be said that it is an attempt of 2.5-dimensional stereoscopic display. However, unlike two-screen image recognition, such as essential species with eyes on both sides, primates are looking forward and perceiving a single two-dimensional image and depth recognition. The one-dimensional two-dimensional image and the primate form of depth information are completely different from the 2.5-dimensional three-dimensional display by the two two-dimensional images. The clear proof is that the viewpoint of viewing the image cannot be moved with the two-dimensional image method. In other words, it puts your hand in your brain and makes you feel a sense of perspective, which is the opposite of nature. In addition, the familiar flat display and three-dimensional display must change continuously, but in the binocular parallax method using two two-dimensional images, the flat display and three-dimensional display are discontinuous and consist of completely different foundations. ing.

To put it more simply, humans perceive it as a flat surface in which space is projected by a flat retinal optic nerve. When human beings try to capture in 3D what can already be captured in 2D, a contradiction arises. As shown in FIG. 117, when a color is given to a black-and-white light-dark image, a two-dimensional image on the retina is formed as a two-dimensional object plane on the opposite side of the lens so that a triangle composed of three primary colors is spread. Basically exists. The color is added as information, so that the distant view is left as it is from the two-dimensional object plane so that the close-up view is drawn forward so that the two-dimensional color plane changes from the one-dimensional light and dark. This is the original sense of primates. Especially when jumping from tree to tree, Z-axis distance recognition was a serious perception related to life and death.

The perspective formed by this is not simple false information as expressed by binocular parallax. For example, even if the viewpoint is moved up and down without causing binocular parallax, humans perceive the stereoscopic effect without any change. The same is true for the focus of the eye lens.

In this way, it can be seen that the binocular parallax method is completely fake and has no elements worthy of consideration, contrary to human nature.

<What can exist as a display device>
1) Color liquid crystal, which is a representative display device, uses an FL backlight with an irradiation efficiency of about 15%, and selects it with a color filter, so the aperture ratio is worse than 1/3 of the limit. The overall irradiation efficiency is about 3%. There is no chance that the color LCD will survive in the future. Companies that have the chance to survive are those that do not have the funds to invest in such a uniform. That is the world. Using an LED as a backlight increases the irradiation efficiency.

2) The theoretical limit of the illumination efficiency of the self-luminous organic EL is 25%. There is no future in this.

3) Those whose irradiation efficiency does not exceed 75% cannot survive.

4) The next condition is the relationship between screen size and cost. LCD panels, organic EL panels, and plasma TVs whose screen sizes are related to manufacturing costs from 50 inches to 200 inches do not meet irrelevant requirements, so they cannot survive after 2012, and other uses of manufacturing equipment We must measure the conversion to

5) Lifetime will become a very important issue in the future. The light source is required to have durability for 100 years. The most important thing is that the method has survived and won the trust of people 100 years later. The method should not be artificial. Whether it is in line with natural intention is required.

6) It must also be thin. Since the liquid crystal panel is rigid, it does not satisfy the requirement for thinning, but the organic EL satisfies this requirement with a thread. The display device should be essentially a lighting device and have a film-like appearance on it. Or it must be a projection type.

7) If a durable life comes after 100 years and is to be discarded, the burden on the environment beyond throwing away newspaper must not be given.

8) Rare resources such as transparent electrode In used in LCD and organic EL must be avoided.

9) First, as a flat-screen television, it must withstand the trials of the era of 100 years and be able to perform 3D display as it is.

<CSOP2 as ground solution>
Although CSOP2 can be said to be one of the top solutions, another top solution already exists but is not clarified in this discussion because it belongs to another technical group. However, CSOP2 satisfies the above nine conditions, and LCD does not satisfy any condition. New capital investment in large LCDs has already been solved in a way that does not burn fossil fuels in road traffic systems, and the means and procedures for dissemination are now clear, just as stupid as we aim for globalization now ing. What is concerned is the disposal of what these global companies produce.

What is needed now is to make clear what is not allowed by nature and not what humanity can do. The fossil fuel cannot be burned out. Fusion cannot exist on the ground. Because human beings already have a fusion factory called the sun since ancient times. The magnetic levitation railway cannot survive. Because it is not natural law. The year-round temperature is constant at a depth deeper than 1.7m underground. This is because the heat capacity of air up to the stratosphere is equal to the heat capacity of soil with a thickness of 1.7 m, and heat exchange is performed including the sea that occupies 2/3 of the earth's surface. Human tools that do not understand this principle, especially after the Industrial Revolution, are not comfortable. They are simply believed to be comfortable.

The creator always has an answer. CSOP2 does not match that. However, it has a requirement as a ground solution. CSOP2 is a very good scanning line TV. Nostalgic interlace is also effective. The irradiation efficiency of CSOP is about 80%, which exceeds the above examination standard of 75%. The resolution does not depend on the screen size, the distance from the projector to the screen, and whether it is used for a flat TV or a stereoscopic TV.

The case where the CSOP 2 loses the characteristics of the stereoscopic image display is a case where it is projected once on the screen and converted into a scalar. On the other hand, when it is projected on the screen of a human retina, it is a stereoscopic image.

In a stereoscopic image experimental machine such as the NTT system, it is possible to forcibly make a stereoscopic image with CSOP while projecting on a screen. If two screens are used as in the NTT system, the front screen is made translucent so that the same image overlaps from the viewer's viewpoint, and the luminance formed on the front and back screens is proportionally distributed, 1 A similar projector can be realized with a much simpler procedure by placing a projector next to the viewer. However, this is based on the illusion of image recognition including the human brain and is not a meaningful device. Place the CSOP2 on the wall and face the viewer, place images as a collection of equivalent point light sources in the surrounding 90cm x 160cm frame, use it as it is if you want to stick to a thin display with a thickness of 10mm or less. Otherwise, a stereoscopic image may be displayed in a space having a depth of HxWxD of 90 cm × 160 cm × 80 cm. There is no difference in component configuration and manufacturing cost between the two usages as CSOP2. Therefore, it is only necessary to project from the beginning into a solid space of 90 cm × 160 cm × <0 to 80 cm>. In this way, it is the supplier's belief that promoting thinning is the same as saying that your face is flat. Rather than that, I'd like to ask you what the environmental impact is like when you dispose of it, and how much device miles you have.

An important issue for CSOP2 is the radiation of heat. LCD-TV, which was 40W in the past, becomes 1.5W in CSOP-TV. The viewing angle is not much different from LCD-TV. Since it is meaningless to see a stereoscopic TV from the side, the concept of viewing angle is abolished and attention must be paid to personalization. Of the 1.5 W, about 200 mW is dissipated as heat rather than effective light from the LD array chip, and about 500 mW is generated from the driving silicon chip. Although there is no large heat generation like the liquid circulation cooling of the projector using CRT and the xenon bulb required for the LCD projector, it is an unusual amount of heat generation as a 21st century type product.

The resolution of CSOP2 depends on the phase synchronization in the LD array chip. In the case of NV with 16 circular radiating array rows, only the phase synchronization within the circle is important. This is because the 16 divided scans scan at the same timing as two wipers of an automobile, so that the light does not interfere between the circular radiations. Since there is no Big-Phased-Loop between the reflective surface of the optical disc as in CSOP1, a Big-Phased-Loop is configured by placing a reflective plate with a distance on the back surface of the LD chip.

CSOP2 is a three-primary color system, in which RGB three-plate LD arrays are superimposed without using a half mirror or a dichroic mirror. For this reason, raster distortion and convergence have the same problems as CRT, but are electronically controlled by mathematical calculations.

The RGB1 set can be drawn on two different screens, and the true stereoscopic TV display remains the RGB1 set. This is called one set of three plates.

In proceeding with the correct design of the optical system, if the vague term coherency is not abolished, the engineer who uses it will be a disappointment.

FIG. 110 shows the difference between the stereo pseudostereoscopic method and CSOP2.

<Mobile phone terminal>
The CSOP2 is embedded in a mobile phone terminal and forms an equivalent image in a 20 cm x 30 cm x 10 cm stereoscopic image space (virtual image). The parts cost is about 2500 yen, so it is bright even under sunlight. The cost is lower than that of a small LCD panel and power consumption is low. Since the 3D-GUI is more comfortable than the touch panel method, the touch panel method will not survive. There will be no point in using CSOP2 and a conventional small LCD panel together.

When watching a TV with a size of 50 inches at a travel destination, a 900 mAH lithium ion battery can only be watched for one hour. However, it is most suitable for a family to watch a 200-inch NV stereoscopic TV connected to an external power source.

Natural law makes it meaningless to replace mobile phone terminals in 1 to 3 years. Because, while using the 800 MHz band, all of the 1.5 GHz band, 1.7 GHz band, 2.0 GHz band, and 2.5 GHz band communication bandwidth is moved to the 800 MHz band, and the current transfer rate is doubled. A system that reduces the burden on base stations has already been developed based on 21st century physics, and based on its scientific principles, operators can only choose to quit their business or to comply with 100-year lifetime rules. Because there is no.

Considering a state in which an RGB3 plate CSOP is incorporated in a mobile phone terminal, there are two display methods.

1) Flat screen TV projected on the screen
2) Stereoscopic TV looking into the RGB3 board

Of these, 1) is easy to understand with the same concept as the conventional projection TV. Regarding 2) 3D TV, it takes time to understand correctly. I draw in the air with a pen or a mobile phone terminal in an SF movie, but that is impossible. Because there is no screen there. RGB No. 3 must be directed to people. The head-up display of an automobile has a slanted window glass, so it can be drawn forward. With CSOP, a spot can be imaged at XYZ coordinates around three plates. The image captured by the retinas of both human eyes is the same as when capturing a human three-dimensional space. FIG. 111 shows the difference between the two modes.

Mobile phone terminals, when combined with CSOP2 and Ryo's keyboard / mouse, have already been given responsibility and obligation beyond the implications of multifunctional telephone terminals, and people living on the earth have benefited from the fundamental science. It will be one of the ways to return to. MIT's Negroponte's $ 100 PC with a hand-wheel generator is truly prepared here.

FIG. 112 reviews the basic functions of CSOP2.

<Wearable PC>
Billgate's wearable PC is more familiar with an Apple computer that doesn't forget the importance of hardware. FIG. 113 shows a typical form. The keyboard and mouse are ready to go into mass production wirelessly / electrically. The display is a three-dimensional type that is projected onto the screen with CSOP2 or directly viewed. Ryo's full keyboard can be rolled up into a breast pocket.

Although CSOP cannot eradicate cancer, it is thought that those who die from cancer will disappear from the planet, so the remaining challenge for Bill Gates who proposed wearable PCs is a slight change in the window OS platform for 3D-GUI And to eliminate those who die from AIDS. There is no contradiction in the Vista window stream to ride the flow.

<Common format for plane, stereoscopic video, 3D-GUI, 3D-Game>
It reproduces the image close to nature without giving a basic difference between the plane image information and the stereoscopic image information.

1) When a stereoscopic image is displayed in a space, it is unavoidable to see through the background because of additive color mixing. In particular, when a 3D primary color LD plate is directly viewed (direct view) on a portable terminal and a stereoscopic image is raised around it, a dark background cannot be selected.
2) In the projection type (projection), even if the foreground is imaged on the screen and the foreground is imaged in front of it, only the re-radiated light from the screen will enter the eye, so the foreground is reflected, but the foreground is Only the defocused image on the screen appears. That is, in the projection type, there is only a method for viewing stereoscopic image information by compressing the Z axis into a flat image having no depth.
3) In order to correctly view stereoscopic image information, a 3D color LD plate is directly viewed in a black background, and a stereoscopic image formed in the space in front of the background is flattened on the retinas of human eyes. There is no choice but to re-image as an image.
4) If the phase synchronization of each of the three primary color LD plates is perfect, the active layer itself of the three primary color LD plate cannot be seen in the stereoscopic image viewed directly. All of the light emitted becomes a stereoscopic image. The phase imperfection is superimposed on the active layer of the blurred three-primary-color LD plate behind the farthest view in the stereoscopic image, but if the imperfection is known, it can be canceled by a negative stereoscopic image.
5) Even if a single screen is made translucent by rear projection, the images defocused on the screen overlap, so that a comfortable stereoscopic image cannot be obtained.
6) All images are flat images. This is because the image shown on the human retina is a planar image.
7) A planar image can be easily converted into a stereoscopic image. In that method, an object in the image is inserted into a deep space.
8) Give coordinates on the Z-axis for each pixel or area (texture).
9) It is a basic property that any stereoscopic image information is a flat image with no depth.
10) Line up and down according to the depth information on the Z-axis only when necessary. When the use is finished, it is quickly compressed into a flat surface.
11) Three modes are allowed for Z-axis deployment. First, the background is Z = 0 and the last part is placed, and the other is placed in the foreground. Second, set Z = 0 at the forefront, and keep others away from it. Third, an object at an intermediate position is set to Z = 0, and other objects are arranged before and after that.
12) In the direct view type, when the Z axis coordinate of the foreground is set to 0 and the foreground is imaged to the positive Z axis coordinate starting from the active layer of the three primary color LD plate, the imaging scan of the XY plane is performed. When performed without cuts as in the case of a planar image, the viewing angle for viewing the foreground as viewed from the viewer increases. As a result, the viewer sees the foreground clipped from the background, and creates a portion that visually overlaps the background. The range in which the overlapping portion can be held is the range of the place where the family can enjoy the stereoscopic image.
13) Since the portion where the foreground and the background overlap is the image information originally included in the planar image, the stereoscopic image has only the same image information as the planar image. Only the Z-axis coordinate of the area is added as a tag.
14) The presence of the background portion hidden by the foreground eliminates the contradiction between the left and right binocular parallax, and the contradiction when moving the face up and down. The viewer may lie down.
15) Because of the additive color mixture, the overlapping portion of the background can be seen through, so the overlapping portion of the background erases the image for a single viewer.
16) 3D-Game and 3D-CG use the same format. In particular, the PC screen is based on a two-dimensional multi-window, and the foreground is projected only when necessary.
17) Specify which of the Z-axis hierarchies before and after the mouse pointer / handle of the 3D-GUI is XY-scanned, or display the hierarchies divided by color or the like.
18) A stereoscopic image is operated in conjunction with a personalized true stereoscopic sound image, and both individual viewers have RFID markers.
19) Stereoscopic image display does not cause a contradiction between binocular parallax and focus (eg, CSOP)

<Common format for planar and stereoscopic video photography>
A single camera is used for both planar image capture and true stereoscopic image capture. Shooting a binocular parallax pseudo-stereoscopic image uses two cameras, and editing work and image processing for image synthesis are required, but true stereoscopic image shooting is no different from shooting a planar image. Depth information for each pixel area is read by a focus function attached to the camera and added to the planar image information as a tag.

The three-plate single broadcast camera of the system shown in FIG. 114 easily achieves a resolution of NV (7680 × 4320) and captures a plane image itself, which is a recording of a stereoscopic image.

<Image compression format>
MPEG2 / H. The H.264 image compression format, which has a slightly unfocused feeling, is essentially permanent because the lifetime of the surface emitting LD exceeds 1 million hours (100 years). In fact, it means that the compression rate of image compression is not man-made, and there remains an opportunity to correct the defect due to human imperfection with a correction that maintains compatibility. The constant development of human society is the greatest sin in human history brought about by the pioneering spirit that raises a new territory and raises a flag in the competition for personal possession.

Since the stereoscopic image display is a concept of rendering a pixel area in a three-dimensional space, a TV, a movie, a CG, and a game are placed on one base. Image compression is performed on this pixel area. This TrueType subdivision increases the amount of information slightly compared to MPEG that compresses BitMap images regardless of the area, but the reproducibility and original white noise resistance exceeding that are obtained as recognition type compression, and the adverse effects of block noise are Disappear. Originally, MPEG had thrown away Z-axis information that was indispensable for recognition.

The two-dimensional current distribution of the LD array for displaying an image in space is a display image obtained by DCT conversion. Therefore, NPEG based on this natural law can be defined to make a 100-year format.

<RGB convergence>
When CSOP is used in a projector, RGB convergence is the same as raster distortion / convergence of an RGB inline gun in a color CRT, but handling is simple without distortion such as DY (deflection yoke) pincushion / barrel. is there. In the case of the RGB in-line gun in the color CRT, it is difficult to control the RGB electron beams separately, but the current distribution can be individually controlled in the CSOP.

<Join split images>
The SV of 3840x2160 resolution is preferably divided into four CSOPs, and the 7680x4320 NV is divided into 16 CSOPs. All the smooth stitching of the screens in that case is done electronically. To adjust this automatically, create a reference plane and place the screen there. Switch to the CSOP imaging mode shown in <0083> below, detect the joint portion of the CSOP imaging raster in one projection mode with the adjacent CSOP, and automatically join the images by matching the position and brightness level Can do.

<Synchronization with 3D sound image>
The CSOP HV / SV / NV stereoscopic projector has a bright image, has a lifetime of 100 years, and has a manufacturing cost of about 1/10 of the LCD-TV. In this case, the projector itself is a location TV that is about the same as a mobile phone terminal. Except for the purpose of grouping, it is considered that there are many forms in which individuals individually view 100-inch stereoscopic images rather than watching a single screen with their family.

In this case, the conventional speaker system cannot separate the sound fields in the same room. Also, the 5.1 surround sound is too poor, while the image is three-dimensional and has a high resolution. Also, the current speaker system does not have a 100-year life. Further, since the power consumption of CSOP is 1/20 of that of LCD-TV, 10W + 10W of the speaker should be 100 mW + 100 mW. In addition, in order to match the manufacturing cost of CSOP, it is desired to make the manufacturing cost about 1/10 that of a conventional speaker. I also want to improve the sound quality of conventional speakers. These strict requirements are easily realized by the configuration of FIG. At the same time, the electrostatic micro-speaker / microphone array is an RF antenna array (the RF broadcast signal is weakly re-radiated at one point on the location TV, and wireless power transmission (80% efficiency) is performed in a completely different way from MIT for viewing. The three-dimensional position of the RFID tag worn by the person is specified, where the wavelength of the sound wave of 1 KHz and the wavelength of the 900 MHz RFID carrier are the same length.

As for the sound field, it creates a natural sound field environment around the head that humankind has never been able to embody. Instead, abandon that the skin and flesh of the belly vibrate. A sound source is created with phase concentration in every direction around the head, and the right ear and the far right are distinguished. The sound field separation between families in the same room is almost perfect. If you move your head 30cm to the left, you can go back to the foreign sound field from Japanese and return.

Synchronizing with a three-dimensional circle image means an array for RF signals, an array for power transmission, an array for collecting voice and preventing the surrounding sound from entering the videophone, and a three-dimensional sound field. , An array for MPEG radio wave streams, and an array for wireless keyboards on a single board.

The system is extremely inexpensive and the term digital inequality becomes a dead language. CSOP is a gift from the Creator to those who realize that they will live in the 21st century.

<CSOP imaging>
A color filter CCD / CMOS imager is an excellent imaging device, but it is a ground solution and must fight against lattice defects and the number of pixels. It is not immediately imaginable to ship a CCD / CMOS imager with a resolution of 7680 × 4320 for 10,000 yen (133 million pixels).

When the CSOP is focused far away toward the scenery and the XY scan is performed, the external light as the scenery becomes an external light disturbance to the phase synchronization of the LD array. External light from a mainly focused location is a significant disturbance, and disturbances from other locations are noise. Noise can be subtracted from a two-dimensional disturbance distribution obtained by DCT transform of an image. This imaging device does not require a color filter. The wavelength of the LD already has wavelength selectivity. If you compare this to an electric circuit, there is an LC resonance circuit that has a constant self-noise level (spontaneous emission of LD) and resonates at a certain level at a certain phase, and natural light is injected into it as noise. Since the light from the spatial scanning point in phase matching is phase-synchronized by the LD array, it selectively resonates with the bandwidth of the wavelength. If this is detected by noise intensity, line-sequential imaging output is obtained.

CSOP is a stereoscopic imaging device, and depth information can be obtained simultaneously.

Comparing the dark noise with the CCD / CMOS imager is a comparison between the collective spontaneous emission level of the LD array and the product of the dark current and input resistance of the CMOS imager.

The obtained DCT signals are matrixed to obtain Y, RY, and BY signals.

In the process of focusing, Z-axis coordinate information of the pixel region is obtained.

Since the video shot by the CSOP imager is a two-dimensional DCT output, it is similar to the CSOP already performing most of the CCD / CMOS imaging and JPEG conversion processes of the digital camera.

This CSOP imaging, broadcast radio wave, recording medium, image editing, and CSOP stereoscopic image display are consistently performed in the DCT domain, and since there is no humanity, it is a 100-year format top solution. This is called NPEG (natural image compression). This is based on the natural law given by the Creator, and the format battle ends. The equivalent of a conventional MPEG encoder / MPEG decoder is responsible for time axis compression processing.

A CSOP as a 3D image pickup plate does not require a lens. Therefore, the telephoto lens and the close-up lens have no concept.

CSOP as a 3D image pickup plate does not have the concept of overscan for preventing camera shake like a CCD imager. This is because even if the camera shakes, there is no mass in the servo necessary to lock on the object angle of view.

The CSOP imager becomes a 3D projector as it is.

FIG. 114 shows the mechanism of the CSOP camera.

<CSOP scanner application>
The CSOP NBD recorder / player becomes a scanner. If a CSOP of RGB wavelength is thrown into the flatbed mechanism, the surface of the paper is scanned as an RF-Identified Flying Object, electromagnetically levitated, and aligned so that RGB does not collide by delaying time. The resolution is about 0.5 um and is 50000 DPI.

<CSOP printer application>
The CSOP NBD recording / reproducing machine becomes a plain paper printer as it is. If an infrared wavelength CSOP is thrown into the flatbed mechanism,
As an RF Identifying Flying Object, black and white characters are written by electromagnetically levitating and carbonizing plain paper.
The flatbed mechanism must be robust so that it can withstand gas exhaust and can be washed. The use of CSOP as a light emitter without a movable mirror and lens in a 20th century laser printer is not excluded. A color printer uses a method in which spots are applied to special paper on which RGB paints and pigments are evenly printed to infiltrate or break the capsules to break the white balance and develop colors.

<CSOP 3 in 1 tool>
Flying-CSOP performs recording / reproduction of a flatbed scanner / printer / NBD. The normal form of a notebook PC is an A4 size flatbed mechanism with MPU and I / O. Letter size will be abolished or this patent will not be licensed. The flatbed mechanism is connected to a mobile phone terminal, and the mobile phone terminal performs stereoscopic display with a size of about 20 inches with a resolution of 1920 × 1200, and the irradiation efficiency is 20 times that of an LCD display. In direct view type, there is no screen to project. The sound is personalized with true 3D sound, and the power consumption when a person feels the same volume is 1/30 of the conventional sound. HMI is a battery-less, wireless Ryo's keyboard / mouse. The CSOP projector with the 1920 × 1200 resolution of the mobile phone terminal switches to the CSOP camera mode with the 1920 × 1200 resolution. The wireless Ryo's keyboard / mouse can be rolled up and stored in a pocket such as a chest along with a mobile phone terminal, and the weight of the flatbed mechanism is 300 grams, so it is lighter than a notebook PC with a current 20-inch screen. And much more robust. Flying-CSOP does not cause a problem in operation even if the corner of the case is crushed by dropping the flat bed mechanism onto the floor.

<LD wavelength conversion mechanism>
It was a wrong social event in the 20th century to compete for shortening the wavelength and to argue about who's invention in recording and playback of optical discs. Shortening the wavelength is meaningless in the 21st century. Even now, in the 21st century, it is anachronism to do it. This is because the LD resonance mechanism irradiates, for example, 780 nm AlGaAs LD light to the 405 nm LD resonance active layer. This is because light having a phase of 317 nm can be extracted. From this point of view, meaningless conflicts should be stopped.

Non-linear elements are required for frequency conversion. However, in the 21st century physics world, there is no sudden process like the photoelectric effect that Einstein had to lie without a heart. Everything is a reality in a perfectly linear world. The means prepared by the creator for wavelength conversion is spatial non-linearity in which LD resonance is phase-synchronized with a threshold current as a boundary. The forward radiation suddenly increases by a factor of 100 and is close to perfect switching operation.

<Creation of three primary colors by wavelength conversion>
If there is a green LD with a wavelength of 532 nm, that wavelength is used as one of the three primary colors, and if the LD is irradiated with LD light with a wavelength of 2.9 um, as shown in FIG. Red light is obtained.

<In-vehicle head-up display and announcer prompter>
Instead of the conventional head-up display reflected by the windshield for in-vehicle use, the CSOP direct view or the direct view plane / stereoscopic image reflected by the windshield is superimposed on the foreground for safety It can be used for countermeasures. Use a CSOP direct-view plane / stereoscopic image for the prompter.

<CG video production and CSOP>
Conventionally, the combination of animation and real person has synthesized different policies with CG technology. This takes an enormous amount of time to synchronize. Since CSOP can display a real person and a CG stereoscopically, it is easy to synchronize.

<Requirements>
(1) A surface emitting LD (laser diode) consisting of a plurality of active layers on a single chip, which has a wavelength / NA (numerical aperture) limit at the focal point separated from the light emitting surface by an operating distance F on the central axis. A spot is formed so that it has the functions of both an LD and an objective lens. Light emission from adjacent active layers having the same resonance length L resonates at the same wavelength and emits light, but at the same time, the light emission channels emit light of the same phase in phase synchronization by electromagnetic coupling. As a basic form, the active layer is divided into concentric circles around the central axis and arranged in multiple layers up to the radius R. NA as the condenser lens is a sine formed by R and F. The light emission center of each light emission channel viewed from the outside is a point entering from the surface by a length obtained by dividing L / 2 by the refractive index n of the medium. A condition for forming a spot at the focal point is that the difference in wave number obtained by measuring the length from the emission center of each active layer to the focal point with respect to the wavelength is an integral multiple of the wavelength, thereby causing phase concentration. The spot diameter is approximately 1.2 wavelengths / NA. Not only the multiple concentric circular arrangement, but also a multiple square arrangement adapted to the shape of the chip is included. When the same current is supplied to each light emitting channel, the distribution is uniform, and the distribution between the conventional ordinary LD-objective relationship up to the cosine distribution can be freely selected. An LD chip is placed on a silicon IC chip that individually controls the drive current of each diode, and is bonded by a solder bump method or the like. In addition, the NA value can be selected by preventing the drive current of the outer concentric active layer from flowing.
(2) Each concentric circle that causes phase concentration at the focal point is made into a double circle, and the active layer is arranged on the entire chip so that the radius r and the radius rr correspond to the focal length F and the focal length FF. By switching the current / current that drives the active layer, the focal length can be selected from two. Further, the focus can be continuously changed from F to FF by changing the ratio of the drive current flowing in the double circle under the condition that each active layer passes a current larger than the threshold current at which the LED operation changes to the LD operation ( Focus). Also, the concentric circle is divided into two at 180 degrees, and the half circular current ratio and the other half circular current ratio are changed in reverse, so that the spot swings in the divided direction while maintaining the same focal length ( Tracking). Further, when a transparent plate having a thickness of 0.1 mm to 1.2 mm is inserted between the LD and the focal point, astigmatism corresponding to the transparent plate is generated, but the light is refracted by the plate into which multiple concentric radii are inserted. Astigmatism is corrected by changing the current ratio of the double circle progressively according to the arranged radial position so that the difference in wave number with the wavelength shortening due to the rate becomes an integer, but at that time, the LD Also correct astigmatism given by the depth to the emission center. Also, the astigmatism correction amount can be selected by changing the current ratio of the double circle so that the astigmatism correction of the thickness of three types of 0.1 mm / 0.6 mm / 1.2 mm can be switched. To do. Also, the concentric circle is divided into four at 90 degrees, the quadruple double circular current ratio is changed in the X direction and the Y direction, and the center axis of the LD chip is shifted from the right angle with the plate with astigmatism inserted. Asymmetrical astigmatism (skew error) can be corrected in the X and Y directions. In practice, these corrections should be given as continuous changes throughout the circle of the LD array chip.
(3) A silicon chip, which is a stage on which the LD chip is placed, is made larger than the LD chip, and four PDs (photodiodes) are placed on the silicon chip outside the LD chip at a position corresponding to the center of the four sides of the LD chip. The return light applied to the spot is detected and used as a return light intensity, focus error, tracking error, and skew error signal.
(4) A CSOP (chip size optical pickup) having a four-part PD and driving a multi-active layer LD chip is used as an optical disk pickup in which the electromagnetic servo function is replaced with electronic current control. In addition, electronic current control of CSOP should be several um to several tens of um with high speed and small range, and low speed and medium range control should use electromagnetic servo function. In addition, electronic current control of CSOP is limited to plate thickness correction and offset correction, and overall motion control uses an electromagnetic servo function.
(5) When a CSOP having a 4-partition PD and driving a multi-active layer LD chip is used for recording / reproducing of an optical disc, the spot diameter required for each CD / DVD / BD is set to each of the light-emitting active layers. To obtain concentric currents by dispersing them from phase concentration.
(6) Compared to the resonant path length of the edge-emitting LD used in an ordinary optical disk, the resonant path length of the surface-emitting LD is made shorter and the number of waves is small, so that it is difficult to enter the multi-wavelength mode. Reflectance of the back of the resonance path is close to 100%, and the radiation surface is increased to several tens of percent or more by raising the transmittance significantly than usual. Internal reflection on the radiation surface is necessary for transition from LED mode to LD mode. The reciprocal resonance is established between the operation in the spot state of the mirror surface portion near the reflectivity close to 100% on the back surface of the resonance path and the reflectivity close to 100% on the disk surface, and the monochromatic wavelength is set. Eliminates the multi-wavelength mode, loses the meaning of the term return light disturbance, suppresses the occurrence of dark lines, enhances the frequency response of the intensity modulation of LD light to the limit, significantly reduces current consumption, and stabilizes the system Make it. If the spot hits the pit part, the light intensity distribution of the return light can be made in the entire LD chip, but the resonance system should be optimized and used. When the large resonance loop is taken by the back surface of the active layer and the mirror surface of the optical disk, it returns to the original active layer in two reciprocations since it is incident obliquely on the disk.
(7) When a CSOP having a 4-partite PD and driving a multi-active layer LD array chip is used for recording / reproduction of an optical disk, when the LD array has a circular distribution, light is emitted at each of the four corners of the LD chip, which is an empty space. Make a point. These four lights are phase-synchronized with the light in the circle. Whether the same current is supplied to these four markers LD, the current is sequentially switched, the modulation is performed with four frequencies, or the switching is sequentially performed with one modulation frequency so that the order is known. These four markers are primarily supplemented by the fact that the focus servo does not change in the amount of light corresponding to the focus error in the four-segment PD arranged on the four sides when the disk is overfocused in the mirror part of the disk. Is used to detect focus errors, tracking errors, and skew errors as a whole.
(8) In the LD array having a condenser lens function, when the resonance is taken by the back surface of the active layer and the mirror surface of the optical disc, it can be said that dark lines are hardly generated compared to the case of using the conventional edge-emitting LD. However, if it occurs, avoid that point (current off), and adaptively reconstruct the optical characteristics by looking at the return light distribution in the Test pit.
(9) During reproduction of an optical disk using CSOP, the intensity of the irradiation light is modulated at about 5 multi-frequency, and the intensity ratio of each frequency can be selected in a circular LD array. The light illuminates an area containing multiple tracks or a block, but is a spot focused on each frequency focused on a separate track and used to compensate for crosstalk due to side lobes determined by NA? Each of the 12 × 12 pits in one block is used for independent detection, and is separated by about five filters after it is detected by a quadrant PD.
(10) When a single spiral optical disk is a multi-pit row, for example, <1 pre-groove + 8 tracks>, and the rotational speed of the disk is about 1/8, for example, 8 tracks are simultaneously written using CSOP. This is achieved by assigning a separate distribution for 8 tracks to the current distribution of the circular LD array.
(11) It is possible to separately record 8 parallel tracks with a single wavelength with a single CSOP, but the rotation speed is about 1/8, for example, and the beam stays at the same place for 8 times longer By using what is being done, the light emission is high-frequency modulated to help it become amorphous.
(12) When the radiated light that is electromagnetically coupled and phase-synchronized with the light emission channels of the three-striped edge-emitting LDs in which the active layers are arranged in parallel is focused by the objective lens, the side lobes adjacent to the main beam are The weighted addition of each light emitting channel should be canceled as one dimension. Similarly, surface-emitting LDs having 3 × 3 light-emitting channels are similarly electromagnetically coupled and phase-synchronized to perform the same two-dimensional sidelobe cancellation. Also, do not provide the four corner channels of the 3x3 array, but perform the same two-dimensional sidelobe cancellation in the shape of a cross.
(13) In order to remedy the life of an optical disk player determined mainly by the growth of lattice defects in the dark line of the LD, a combination of a multi-striped edge-emitting LD and a quadruple PD is extracted from the PD array. An OP (Optical Pickup) device that allows the dark line to grow up in tens of thousands of hours and switches to the next combination by selecting from the row in an optical manner.
(14) Using a single phase-synchronized surface-emitting LD array to form and erase an erasable optical disk simultaneously, forming an erasing spot of the required intensity with a specific current distribution, A recording spot having the intensity obtained by another current distribution is formed, and the current distribution is superimposed on the recording current that has been turned on and off, and is given to the LD array.
(15) In the CSOP configuration, the center of the LD array should be non-radiating, and a 4-partite PD should be placed there.
(16) The optical path of the PD array and the LD is an OP of an optical disc that does not maintain a mirror image relationship by being separated by a half mirror, and the front and rear positions along the optical axis of the PD array and the LD are not necessarily matched. Thin LD light should be emitted from between the array rows. At the time of recording, the emitted light of the LD becomes the smallest spot in the phase change / dye reflectance change recording layer, and the PD array does not necessarily focus the tracking error / focus error / skew error information from the pregroove on the PD surface. In the reproduction, the bright / dark image on the recording surface / pit surface is just focused on the PD array surface, and the emitted light of the LD does not necessarily focus on the recording surface / pit surface, but functions as irradiation light for the region. To do. This OP mechanism is called a modern format, and a conventional method in which a conventional PD and LD are mirror images and a half mirror is always used is called a classic format. All existing OPs are in the classical format.
(17) Light emitted from the LD is converged without chromatic aberration on the pit surface after being reflected twice by the primary reflecting mirror and the secondary reflecting mirror, and the PD array is placed behind the primary reflecting mirror toward the disk surface. , RF signal / tracking error / focus error / skew error contained in reflected light from recording surface / pit surface without passing through lens / reflector, small size, light weight, thin shape, low manufacturing cost, low OP mechanism for obtaining the number of parts. This is called the modern form. In the modern format, the secondary reflecting mirror is generally fixed in the relative positional relationship between the disk and the OP, and the tracking servo / focus servo / skew servo can be applied mainly by moving the primary reflecting mirror. Further, the secondary reflecting mirror is not limited to the parabolic mirror, and a planar reflecting mirror defined in FIG. 50 should be used.
(18) It has the same wavelength of light 405 nm as that of the Blue-Ray disc (BD) and the lens NA (= 0.85), and the miniaturized PD array can correct inter-track interference and inter-symbol interference in the same track. This is called Enhanced-BD (EBD), and ED is 25 GB, while EDB can read and write 40 GB. The track pitch of BD is 0.32 um, whereas the track pitch of EBD is 0.24 um. Make BD readable and writable with EBD OP. In order to compensate for the inter-track interference during reproduction, the emitted light of the LD is defocused on the recording surface / pit surface, and the area is irradiated for a range of 5 tracks or more. Equalize to correct intersymbol interference during recording.
(19) Use a double-stripe LD twin peak spot that can be simultaneously erased and written.
(20) Erasing / recording / reproduction is performed by forming three spots with an edge-emitting LD having three stripes in order to avoid frequent waste of writing and waste of resources and time during the optical disc recording method. To be able to rewrite by continuously performing.
(21) A plurality of spots are formed by multi-stripe end-emitting LDs, and read and written in a distributed manner with a delay amount according to the linear velocity, thereby correcting aperture by velocity modulation, improving S / N, and photocurrent. Useful for reducing and suppressing the growth of dark lines.
(22) An OP structure for reading and writing a CD / DVD with a single LD light source having a wavelength of 650 nm, the protective layer thickness of the disk being 0.6 mm, which is the DVD operating condition, NA = 0.6, and a track pitch of 0 From the light spot diameter corresponding to .74 um, without adding new parts or mechanisms, the track pitch of the protective layer thickness of the disk is 1.2 mm, NA = 0.4 to 0.45, which is the operating condition of the CD In order to eliminate the astigmatism problem caused by the difference in the thickness of the protective layer of 0.6 mm, which is the most problematic for the purpose of creating a light spot diameter corresponding to 1.6 um, the distance b between the disk and the objective lens is b. The ratio a / b of the distance a from the objective lens to the LD emission point with respect to is doubled in the DVD mode and the CD mode, and the image of the CD protective layer thickness is the same as the image of the DVD protective layer thickness. To ensure that appear to be.
(23) A single OP that reads and writes CD / DVD / BD (/ EDB), and uses only two light sources having a wavelength of 650 nm and a wavelength of 405 nm, and the two optical paths are separated by a half mirror, DVD and CD are read and written at the wavelength, and NA = 0.85, which is a common lens, is irradiated in the range of NA = 0.6 at an emission angle of LD of 650 nm for CD / DVD use. Further, since the protective film of the disk is equivalent to 0.6 mm for CD / DVD and equivalently 0.1 mm for BD / EBD, the compensation on the opposite side of the objective lens for the amount of astigmatism is half. The astigmatism amount in the transmission path of the mirror and the astigmatism amount due to the depth of the light emitting point of the LD are made equal to each other, and what corresponds to many conventional astigmatism correction plates is removed.
(24) Finding and identifying cancer and other lesions with MRI, CT scan, radiography, ultrasound, palpation, endoscope, PET marker, etc., scalpel, laser scalpel, irradiation, administration of anticancer agents, etc. Replaced with or used in combination with these methods, with the aim of ensuring that no one is afflicted with cancer from early to mid-term cancer, and that everyone has cancer but does not die from cancer. Detection and treatment of lesions is less than 1 mSec. Rechargeable battery drive that can detect and treat micro cancer at home under the direction of a doctor using an optical pickup of appropriate single wavelength or composite wavelength including electromagnetic wave region to reduce the error of misalignment by performing at intervals It is a medical device that is about the size of a mobile phone terminal and can be purchased for 10,000 yen or less. In the past, the means for identifying fine cancer and the means for performing treatment on the position were separated, so that the effect of the treatment was hardly obtained. In addition to the large spot diameter, the entire tissue from the outside of the body to the lesion was damaged, but the optical pickup method limited the cell to several tens of um including the depth and destroyed the cells. The location of DNA can be eliminated. In addition, since the conventional laser knife is a thin beam, if there is a tissue in the middle of the affected area, and if there is a tissue behind it, they are all damaged, but the optical pickup method is a remote phase concentration. The laser output is small and in many cases it is not necessary to open the stomach. In the latest radiation therapy, the range of irradiation to the cancer area in the middle and final stages discovered is surrounded by a three-dimensional block to reduce damage to other normal tissues. The focus is on cleaning up in an unaffected state that will take about 20 years and will be of a size that will harm human health. Radiation therapy has three stages of effects on DNA and cells: 1) breaks DNA, 2) replaces DNA bases, and 3) breaks cells, but aims to break DNA. For this reason, DNA base replacement occurs in the periphery of the irradiation where the irradiation level becomes lower, which also causes unexpected cancer in the future. Everything in the universe spreads and appears in one point if there is a means of phase concentration. Scanning a fine spot to finish the whole body takes a long time, so you can do this at home. Also, there is a warehouse behind the lesion point, and when the scanning points are connected as a stereoscopic image, a stereoscopic image of the warehouse and the body is obtained, and there are no points of check omission based on this. It should be a means. In addition, the rechargeable battery drive detection and treatment terminal is connected wirelessly to a PC, and image accumulation is performed by the PC. In addition, because the refractive index of the tissue from the surface of the body to the lesion varies, the light does not converge to one point, so that the sharpness of the image on the PD array where the irradiated light returns as electromagnetic re-radiation of the lesion is LD. Adjust and optimize the array current distribution. If the image on the obtained PD is sharp, the irradiation spot is also promised to be sharp. A lesion can be identified by a difference in electromagnetic response to irradiation light at the lesion, or can be distinguished by a marker such as PET or a photoprotein, and an appropriate light / electromagnetic wave wavelength is selected.
(25) Recording capacity of 100 GB with respect to 25 GB of the BlueRay specification under the conditions of LD light wavelength 405 nm common with BlueRay, disc diameter 120 mm, disc protective layer 0.1 mm, objective lens NA = 0.85 (circular) Make up the super solution SBD (Super-Blue-Ray). The main difference is that the BD is a one-dimensional line recording, whereas the SBD is a two-dimensional surface recording, and the BD is for the purpose of recording a 1920 × 1080 Hivision for 2 hours, whereas the SBD is a top-level solution. SuperVision with 3840x2160 pixels can be recorded for 2 hours with 100GB recording capacity (4 times BD) using image data compressed NPEG. 2. Block with 12x12 pit count . The size is 6 um x 3.6 um. Used with a 12-row LD array, it records 12x12 pits in a two-dimensional block. The active layers of the twelve LDs have sub-active layers at the top and bottom, and the spot can be deflected up and down by the current without increasing the spot diameter. The spot can also deflect the position of the spot in the block in the circumferential direction by delaying the pulse current of the LD. In this way, the deflection amount of the spot in the XY plane can be changed by a combination of 8 × 8 (3 bits + 3 bits) while one pit affects adjacent pits. In addition, the depth of the pit or the size of the spot can be selected from 4 types (2 bits). That is, one pit has a depth of 8 bits (3 + 3 + 2). It has an address groove shared with a block adjacent to the outer periphery of a 12 × 12 block. During reproduction, the LD array becomes area illumination light. The pit image is detected by a subdivided two-dimensional PD array. The detected two-dimensional data is demodulated by comparing the reference two-dimensional data written in the TOC portion with the Lookup-Table, and cannot be demodulated due to disc or OP variations or compatibility, and the error rate increases. Avoid.
(26) A red laser pointer composed of an edge-emitting LD and a lens is switched to a surface-emitting LD, and the optical channels are electromagnetically coupled and phase-synchronized so that an ultra-fine spot can be obtained without using a lens. It must be formed and the heat generated should be sufficiently distributed.
(27) Instead of scanning using a conventional MEMS movable micromirror to draw a TV image on a screen with a laser beam, the current distribution of a phase-locked LD array is changed using a surface emitting three primary color laser pointer. A microprojector (CSOP) that scans the entire screen, and with high resolution, the color LCD has an illumination efficiency of about 3% and a backlight life of 30,000 to 50,000 hours. , Giving an irradiation efficiency of about 80% and a lifetime of 1 million hours or more.
(28) In a microprojector that scans the entire screen by changing the current distribution of the phase-synchronized LD array using surface emitting three primary color laser pointers, each light emission of the LD array is not scanned line-sequentially. To reduce the speed by performing divided scanning as an overlap of complex quantities from the element.
(30) The CSOP is divided into array blocks that are phase-synchronized in each nxm plane, line sequential scanning from each block to the image block is synchronized so that the concentrated point does not approach, and the resolution is secured in units of blocks. The frequency of the current distribution of the driving LD should not be increased.
(31) A plane image is drawn on the screen by scanning with the CSOP mechanism, and an equivalent light emission point sequence (virtual image) of a stereoscopic image is drawn in a three-dimensional space around the light emission surface of the CSOP. In a device that forms a three-dimensional recognition image on a three-dimensional retina, the resolution target is a value obtained by dividing the diameter of a circular LD array by the wavelength of the light. On the other hand, reflectors are arranged at a distance away from the back surface of the LD chip in such a way that the current supply path to each active layer of the LD array is not obstructed, and the average reciprocation length of the laser operation resonance is CSOP. Select the reflectance of the radiation surface so that it is close to or greater than the distance to the imaging point, so that the monochromaticity required for the light source and the phase synchronization in the array can be maintained.
(32) The two-dimensional current distribution flowing through the CSOP is defined by using the projected two-dimensional image or the fact that the third dimension is a DCT (discrete cosine transform) transformation of the image to define an appropriate sky solution NPEG. Performing 2D image or 3D image conversion in the projection space as a CSOP 2D drive current distribution without restoring the compressed DCT data into a 2D image or 3D image.
(33) A CSOP that does not require an optical lens, has a PD for detecting reflected light from printing paper, and can generate two-dimensional multiple spots at the same time, replaces a conventional mechanical part as a part of a laser printer mechanism, and Significantly increase the speed.

The LD array chip is mounted on a silicon chip having a PD and an RF pickup coil, and the LD array current is controlled by the silicon chip.

In addition, in order to simultaneously read out the pit / phase change information recorded in each layer with a common four-segment PD, the clock used when the LD current is written is reproduced and modulated at a frequency that is synchronized with each layer. The pit / phase change is read out, and the output of the four-part PD is extracted and reproduced by a bandpass filter of a corresponding frequency. The resonance between each active layer that reads / writes an optical disc with CSOP adds resonance between the entire LD array and the reflecting surface of the optical disc, and phase-locks at a single frequency. The detection signal is incorporated into the loop so that the focus, tracking, etc. are automatically corrected by using Light from the landscape is externally applied to the active layer of the CSOP without applying a video signal input to the CSOP that draws a planar / stereoscopic image on a two-dimensional screen or three-dimensional space, while only scanning the three-dimensional space with a spot. Although it is input as a disturbance, this disturbance is detected and DCT-converted by utilizing the fact that the LD array is greatly disturbed with light from the vicinity of the spot in the wavelength region of the LD. Use line sequential 3D camera output. When the scenery is scanned in the XY direction, the spot position is moved in the Z-axis direction so that the disturbance of the external light is maximized, and this error signal is used as the depth information attached to the planar pixel area. The output of the stereoscopic imaging camera by CSOP is not the 2D / 3D image information but the disturbance current distribution of the LD array obtained by DCT conversion, and the planar / stereoscopic image drawing by CSOP is the 2D of the LD array converted by DCT. The drive current is returned to the image information.

A CSOP planar / stereoscopic projector incorporated in a mobile phone terminal can be used reversibly as a planar / stereoscopic camera. Instead of the conventional head-up display reflected by the windshield for in-vehicle use, the CSOP direct view or the direct view planar / stereoscopic image reflected by the windshield is superimposed on the foreground for safety Useful for countermeasures.

To get. Also, if there is a green LD with a wavelength of 532 nm, that wavelength is used as one of the three primary colors, and if the LD is irradiated with LD light with a wavelength of 2.9 μm, 450 nm blue and 650 nm red light can be obtained simultaneously. Use this for the three primary colors. The 3840x2160 resolution SV is 4 CSOPs, and the 7680x4320 NV is split by 16 CSOPs, and all the smooth stitching of the screens is done electronically, but this is automatically adjusted To do this, create a reference plane and place the screen there.

Both the three-dimensionally photographed image and the two-dimensionally photographed image are basically displayed as a flat image, and if necessary, the foreground is brought forward according to the depth tag attached to the pixel area. In this case, if the perspective is followed so that the XY scanning of the plane is not interrupted when viewed from the CSOP, the foreground appears larger than the background when viewed from the viewer, and a portion overlapping the background is generated. Use this overlapping part as part of 3D recognition. If necessary, detect the viewer's position and erase the image of the overlapping background. Also, do not put the foreground in the background, but move the background away from the foreground and perform the same process. A similar format is used for 3D-Game and 3D-CG. In particular, the PC screen is based on a two-dimensional multi-window, and the foreground is popped out only when necessary. In addition, clearly indicate which of the Z-axis hierarchies before and after the 3D-GUI mouse pointer / handle is being XY-scanned, or display the hierarchies divided by colors. Rather than aiming for a thin display of 5 mm or less with organic EL, etc., CSOP with a thickness of 5 mm or less, which has been re-differentiated from 16x16, is placed in super parallel to the wall, and stereoscopic images can be seen directly behind the wall or in front of the wall To draw as.
