Description

200827953 IX. Description of the Invention: [Technical Field of the Invention] The present invention is a holographic display device for generating a three-dimensional image, and more particularly, a holographic display device on which an image hologram generated by a computer is encoded. This device produces a three-dimensional hologram reconstruction. [Prior Art] _ Computer-generated video holograms (CGHs) are compiled from one or more spatial light modulators (SLMs); spatial light modulation The device can include electronic or optically controllable elements. These components encode the hologram values based on the image hologram to achieve the purpose of modulating the amplitude and phase of the light. The computer-generated image hologram can be calculated, for example, by coherent ray tracing, by simulating the interference between the reflected light and the reference wave, or by using Fourier # (F〇Urier) or Fico (F bribe) (1) Conversion. An ideal spatial light modulator is a value that can represent any complex number, that is, the phase and amplitude of the incoming light wave are separately controlled. However, a typical spatial light modulator can only control one of the amplitude or phase characteristics, and With adverse effects affecting other characteristics. The amplitude of the county and her has several different ways, such as fine electronic addressable liquid crystal spatial light _, optically-addressed liquid crystal spatial light modulator, magneto-optical spatial light modulator a micromirror device or an acousto-optic illuminator. The modulation of light may be spatially continuous or composed of side-dead components, which may be -dimensional or two-dimensional, binary, multi-level or continuous. 7 200827953 In the present invention The Kui value comes to provide a spatial light modulator control reconstruction for the hologram ship "f word" Qing meaning. Therefore, the °", ', '/ 2" scene can be transmitted through the spatial light modulator On the whole side of the ^ space light modulator coding "green" side in the Lang to change to the three pure automatic dissection display board, observe the extremity image hologram to observe the optical reconstruction of the eye wave front. The three-dimensional scene is extended In the space between the observer's • Lu u I & Guangwei Wei or even the space filament transformer _ $ Construction Inter-Way Modulator can also use the image hologram to encode, so that the observer, in the two faces Wei Zhichao observed the reconstructed three-dimensional scene object, and on the spatial light modulator or the rear view _ other objects. The space light modulation H component is the light transmission side component, the ray caused by the scoop interference to &gt ; in the position of derogatory, and more than a few millimeters of spatial coherence length. Each holographic reconstruction can provide sufficient resolution at least - the Φ type of light will be called "full dimming" In order to ensure sufficient time homology, the spectrum emitted by the light source must be limited to - in a suitably narrow wavelength range, that is, it must be close to a single color. The spectral bandwidth of high-brightness light-emitting diodes (LEDs) is sufficient. Touch to ensure Like the temporal coherence of reconstruction. The diffraction angle on a spatial light modulator is proportional to the wavelength, meaning that only one monochromatic source will result in a strong reconstruction of the target point. A broad spectrum results in a wide target point and blurred Target reconstruction. The spectrum of the laser source can be regarded as a single color. The spectral line width of the light-emitting diode (LED) is narrow enough to help better reconstruction. 200827953 The lateral width of the two separated light sources The light source, such as light-emitting diodes (LEDs) or cold-cathode hairpins (10), can also meet these needs if the light emitted by the searcher is narrow and narrow. The light of the laser source can be regarded as The diffraction source is emitted by the point source, and the purity of the model will produce a sharp reconstruction of the target, that is, each target point is reconstructed as a point of diffraction limitation. The light generated from the non-source of the space is laterally extended. And it will cause the reconstruction to be ambiguous. The situation is determined by the wide size of the target point of reconstruction at a given location. In order to use a lang non-coherent light source for hologram reconstruction, it is necessary to achieve a compromise between brightness and the use of the hole width. Smaller sources will give better spatial coherence. A linear light source can be considered as a point source if viewed from a right angle to a longitudinal extension. Therefore, the light wave can be transmitted in the same direction in the same direction, and it is not in the same direction. As usual, δ, the image of the image is reconstructed in a holographic manner by the coherent super-overlap of the wave in the horizontal and vertical directions. The upper _ full image is called the full side of the full parallax. Reconstructed objects can be considered as parallax in the horizontal (four) straight direction, such as _ real objects. However, the larger visible limb f has a high resolution in the horizontal and vertical directions of the Lang Guang (4). 9 200827953 In general, the demand for spatial light modulators is reduced by limiting to holograms with only horizontal parallax (Hp〇). The holographic reconstruction only occurs in the horizontal direction, and there is no holographic reconstruction in the vertical direction. This will cause the reconstructed object to have a horizontally moving parallax. The perspective does not change on the vertical weave. A hologram with only a parallax will require a spatial light modulator that will have less resolution in the vertical direction than a full-view full-image. An hologram with only vertical parallax (νρο) is equally ok, but rare. A holographic reconstruction occurs only in the vertical direction, producing a reconstructed object with a vertical moving parallax. There is no moving parallax in the horizontal direction. Since the perspectives observed by the left and right eyes are different, the perspectives must be generated separately. DISCUSSION OF RELATED TECHNIQUES Typically, devices for generating three-dimensional images are less compact, requiring complex and bulky optical systems to be rendered incapable of being used in portable devices, or in handheld devices such as cell phones. Take US4, 20Μ86 as an example to generate a larger three-dimensional map. The health length is in meters. WG 2GG4/G44659 〇JS2_/_994) for the tea test 'The device used to reconstruct the image triple image has a thickness of more than 1 cm. ❶ Therefore, the above f device is for mobile phones or other portable, handheld or Small display devices have an excessive thickness. In WO 2G_44659 (_ aim / _994) mentioned by the co-ordinated 200827953 light diffracted money three material scene thief set; money including light flashing light source, for focusing light lens and space light modulator . She is in the space of light and the transmission mode is at least one, and the virtual viewing window dimension scene (for the description of the virtual fiber viewer window and related technology, please refer to the attachment ^ II) ° Each virtual weaver window It is set to watch observation (four) turn, and the big 1, upper limit, so the virtual observer window is in the single-diffraction class, so the mother-eye can see the three-dimensional scene in the _-shaped reconstruction empty _ complete reconstruction, round cone The reconstruction space is extended between the surface of the spatial light modulator and the virtual observer window. In order for the hologram reconstruction to be undisturbed, the size of the virtual observer window must not exceed the reconstructed--a diffraction-level job interval. However, this must be at least large enough to allow the viewer to see the complete reconstruction of the 3D scene via S. The other eye can be viewed by the same virtual observer window or by a second virtual observer's wire produced by the second source. At this point, a typically large visible area will limit the virtual observer window that is in the dark. A conventional solution is to reconstruct a large area of miniaturization produced by the surface of a conventional high resolution spatial light modulator to reduce to the size of the virtual observer window. This will result in a smaller 'heart shot angle' for geometric reasons and a computing device that utilizes consumer levels, i.e., a light modulator resolution sufficient to achieve high quality instant hologram reconstruction. However, it is known that a method of generating a three-dimensional image exhibits a disadvantage of being large in size, large in capacity, heavy in weight, and expensive by the lens of 200827953 due to a large spatial light and a favorable surface area. Therefore, DreamWorks will have a large thickness and weight. Another - a :, f fine field mirror, due to the color difference of the edge will seriously reduce the weight = pin. As mentioned in 6/25_, an improved light source improvement method including a lenticular array is used. In the brain tear, β refers to a mobile phone that produces three-dimensional images. However, the two-dimensional image of & is generated by autostereoscopic display. Autostereoscopic display The three-dimensional image-generated _ thief typically sees the viewer inside the display, while the viewer's eyes tend to focus on the display's watch. In many instances, the difference between the focus of the viewer's eye and the perceived position of the three-dimensional image will be uncomfortable for the month. In the case of _ hologram technology producing a three-dimensional image, this _ question will not occur, or greatly reduced. SUMMARY OF THE INVENTION In a first aspect, a holographic display device is provided, comprising a light source in the form of a two-dimensional array of light sources, a lens in the form of a two-dimensional lens, a spatial light modulation if and a beam splitter, wherein each lens Corresponding to m filaments, and the light source is corresponding to the lens in a m-to-one manner, the beam splitter will be mixed with the light--the silk is divided into two beams, one of which illuminates the virtual observer window for m left eyes, and the other is for the ra Virtual observer window for the right eye. The hologram display device can correspond to one light source for each lens, and the light source corresponds to the lens in a meandering manner, that is, m=l. 12 200827953 The king's image shows that the light-emitting diode can be used as its light source. For example, if the image is provided in two dimensions, the full image is provided in the horizontal and vertical directions. The full image display may be such that the two-dimensional encoding does not generate astigmatism. For example, it is possible for the king image to have a two-dimensional code with vertical and horizontal focus and vertical and horizontal shift parallax in its towel. The 4 full-image display can be in which the beam splitter is a prism array. The holographic display can be in which the beam splitting is - dimensional_recording mirror _. The full detail can be used in which the beam splitter thief _ is integrated or directly on the light viewer, for 2 reflections, diffraction or hologram _. The full Lai Ke is in the towel beam splitter is another lens. It is all about the shield beam that is used as a barrier in the beam. The holographic display can be performed after the ray splitter is in the empty county modulator. The holographic display can be in which the beam splitter is before the spatial light modulator. The holographic display can be used to image each light source by its _ lens imaging to the viewer plane. Depending on the 7F, it can be a given observer. The inter-lens lens of the light source 13 200827953 array will cause all the light sources to be imaged on the observer plane, that is, the plane containing two virtual observer windows. . The hologram display can have an additional field lens in it. The holographic image is not available in order to provide sufficient space for the chick, and the spacing of the lens array is her sub-image-typical size. The full detail can be either the λ! or the point source in the source. The full age can be reversed or holographic in the Wei phase of the towel. ^ 全^柯为为为魏和魏的的细细—拦 shed, and 曰 can be in which the beam splitter is _ or an integer multiple of light _ _ _ distance, or beam Shun is slightly different or 疋 positive multiples on the space _ spatial light adjustment surface spacing to allow for perspective shortening. The grading of the privately accommodating wire is a field ray which is not an implementation in which the light source is tracked. Like the middle rib paste will turn in the left eye to ne~SQUare_ most domain, in the money _ _, *, and another strength package Sinc-S (jUared function into the image display can be in J: towel heart Μ., (four) The maximum value of the virtual observer window is smaller than or equal to the vertical periodic spacing of the diffraction of the spatial light modulator at 14 200827953. Regarding the horizontal (4) horizontal interval of the beam system, the hologram display can be combined with the two-dimensional code of the space multiplex with the virtual observer window. The holographic display can be another lens in the towel beam splitter _ It is static. The holographic display can be a beam splitter mirror that is another-cursor array, and ^ variable. ''Full-image display can be used in order to provide sufficient empty_circumferential, lens array The spacing is similar to the sub-full image _ typical size, that is, from - to several millimeters. The holographic display can be lightly shot for Wei and right _ all sides are - block - intercepting the interlace. The holographic display can be shot The edge of the touch is small enough that the eye does not read the structure of the thief, and the prism The structure does not interfere with the reconstructed image. The Burckhanit code. The hologram display can be used to display the hologram in it, and the hologram display can be used in it. To phase encoding. 15 200827953 Wang Xi 7F can be controlled by the combination of encapsulated liquid-crystal domains in the virtual observer window of the towel, so that the electric field (four) per-area reflection Like the lasing, the holographic display can be controlled by the combination of the liquid crystal layers on the side of the prism _ structure in which the virtual observer « is separated so that the electric field controls the reflection value of the liquid crystal and the diffraction angle of the light. The king image cannot be controlled by the e_w咐_ k mirror column in which the virtual observer window is separated. The hologram display can be close to 100% with a high fill factor in its towel prism array. The distance between the observer and the spatial light modulator is between 20 cm and 4 meters. The holographic display can be between 1 cm and 5 shots. Available The light and the microlens array are illuminated. The microlens array can provide local homology in the region, which is the only part of the display that encodes the information used to reconstruct the wire of the object. The display can include a reflection The polarizer may comprise a germanium optical film. In another aspect, a method of generating a full image is provided, comprising the steps of using a display device as described in the above. 16 200827953 utilizing "spatial light modulation The coded hologram "quotes" means that the hologram is encoded on the spatial light modulator. [Embodiment] A·,, the external line organic light-emitting diode display and the optically-addressed spatial light modulator are closely In combination with the implementation of the optical interface such as the light-adjusting dragon and the infrared light-emitting device that can be used on the optically-spaced space pupil H, the combination can produce three under appropriate compensation conditions. _image. An optically addressed spatial light modulator includes a photoreceptor layer and a liquid crystal (LC) layer positioned between the conductive electrodes. When a voltage is applied to the electrodes, the light pattern incident on the photoreceptor layer is converted to a liquid crystal layer for modulating the read beam. In conventional techniques, the incident light pattern is a write-on beam modulated by an electronically addressed spatial light modulator (EASLM). The sub-spatial address spatial modulator is illuminated by the source and imaged to the optical疋 address space light modulator. Typically, the write beam is non-coherent to avoid speckle patterns, while the read beam is coherent and has the ability to produce a diffractive pattern. The advantage of an optically addressed spatial optical modulator compared to an electronically addressed spatial optical modulator is that optically addressed spatial light tones can have a continuous, non-pixel or non-patterned structure, while electronically addressed spatial light modulation The device is a pixel structure. The pixel produces a sharp edge on the light of the 2008 2008953 jade knife. This sharp edge is equivalent to a high spatial frequency. High spatial frequencies result in wide-angle diffraction in the optical far field. Therefore, the electric address space opto-mechanism will produce Qian Xueyuan's light-weighted out-of-the-way corrections, which must be recorded by known techniques such as space. In the optical processing program, additional steps are required to make the space, which will make the device thicker and cause a light inspection fee. The advantage of the optically-addressed stray light-like actuator is that it allows __ generation to be produced in an optically addressed spatial light modulator. Even the disease depends on the light intensity, with less sharpening in the direction of the beam propagation in any given direction. Therefore, fewer (four) changes have a device that can be compared with the electronic address, and the lower concentration of the high spatial frequency can promote the device. Easy to use and more than contain electronically-spaced light modulators. In addition, she is electronically positioned to lang, and the optical determinator can be dual-sequence. Therefore, the optical slave address space light = sub-slave space light modulation miscellaneous has a lower power demand, "" 曰 式 device or staggered battery life. In this implementation, the rotating device of the imaging wire is not rotated. The light is directly connected to the optically-addressed spatial light modulator in the form of a diode display, forming no = like Kawasaki, she: Yu Yuche _, 18 200827953 into organic light - polar body _. The optically addressed spatial light modulator can be comprised of a plurality of smaller, deployable optically addressed spatial light modulators. , human organic polar body display!! The tight assembly with the optically addressed spatial light modulator can be transparent. Transparent organic light-emitting diode displays are currently known, for example, in the following "Organic Light-Emitting Diode Materials," as described in the section. In a sinister example, an organic light-emitting diode display, and optics The close combination of the spatially-spaced light modulators illuminates the edges formed by the edges to the three-dimensional image, and the visible light is transmitted to the observer via the organic light-emitting body and the optically-addressed spatial light modulator. A better method疋The organic light-emitting diode display emits infrared light to write to the infrared-sensing photoreceptor layer of the optically-addressed space. Because the human eye is not sensitive to infrared rays, the observer cannot see any kind of infrared light-generated beam. Another example of Lu, the close combination of an organic light-emitting diode display and an optically-addressed spatial light-modulating variable allows the writing beam and the reading beam to be incident on the opposite side of the optically-spaced light tone k" In another example, the close combination of the organic light-emitting diode display crying and the optically-addressed spatial light modulator allows the reflective layer to be optically defined. On the side of the spatial light modulator, this is the opposite side of the organic light-emitting diode display, so that the one-dimensional image can be observed from the same side of the optical address space light modulator, especially organic On the side where the LED display is located, the illumination source is also on the same side of the optically-addressed spatial light modulator as the organic light-emitting diode display: 3 anti-19 200827953 Examples of shooting immigrants., including infrared organic In an embodiment of the array of light-emitting diodes, the infrared-emitting organic hair-light body allows for the amplitude of the visible light transmitted by the optically-spaced spatial light modulation, her or the amplitude and her combination (4), the thief hologram Produced in an optically addressed spatial light modulator. The optically addressed spatial light modulator can include two types of electrically conductive films coated on the separator for the Moon Ik plate, as described in US Pat. No. 4,941,735. The continuous or discontinuous photosensitive film can be applied to a conductive film in the basin. μ The read beam of the polarized bistable ferroelectric liquid crystal or some other type of liquid crystal can be used in another conductive film and Between the fine.

However, it is better to have a non-laser light source (for example, a light-emitting diode, an organic light-emitting diode, a cold cathode light) that is well-known to the work of β. of. The shortcomings of laser sources, such as the reconstruction of holograms, cause speckles, are relatively expensive, and all possible safety issues with regard to the hologram of the hologram or the eyes of the assembly staff of the holographic display device. The thickness of the tillage 3 can all be about a few centimeters or less. The component u can be an array of colored light, such that the image of colored light (for example, red, green, and blue light) is directed toward the element 12, although if the color system is used, the color suppression is not required to eat the infrared organic light on the organic tr# coffee substrate.

The physical connection can be extended to achieve the case, the case field is transmitted by the filament, the method is called == miscellaneous = the image is generated (4), or the pair is recorded by it (the wire is made = the component 10 can be One or two mirrored optical films are included to increase the brightness of the display: such films are known, for example, in us 5, 056, 892 and us 5, 9i9, 55i. The elements may comprise polarizing elements or polarized light. A collection of components. ^ Polarized foil is one of them. Another example is a reflective bias, which can transmit a linearly biased state, and a reflective linearly polarized state. Such a thin sheet is known, for example, in US. 5,828, another example is a reflective bias W, which can transmit a circularly polarized state, and a sheet that reflects an orthogonal circular biased state is known, for example, in US 6,181 The inner valley element 10 described in 395 may comprise a focal system, which may be compact, such as a mirror-like array or a microlens array. The element 10 may comprise other opticals known in the art of backlight technology. Figure 4. Figure 4 is a side view of the conventional technology, pointing out The three focusing elements 1101, 1102, 1103 of the direct focusing system 11〇4, in the form of a cylindrical lens arranged horizontally in the array, are referred to reference WO 2006/119920 and collimated with a horizontal line source LS2 nearly 22 200827953. The light beam is exemplified by the focusing element 1102 of the illumination unit to the observer plane 0p. According to Fig. 4, many of the line source LSIs, LS2, LS3 are arranged one above the other. The light emitted by each light source is spatially homogenous in the vertical direction. In the horizontal direction, it is spatially non-coherent. This light passes through the transmission element of the optical modulator SLM. This light is only diffracted in the vertical direction due to the components of the hologram-encoded optical modulator SLM. The component Π 02 has several diffraction stages (only one useful) of the imaging light source LS2 at the observer plane OP. The light beam emitted by the light source LS2 is an example of the focusing element 11 〇 2 passing through the water coke system 1104 as a port. Medium, two ^ 曰 〃 〃 τ two beams show the first diffraction class 11 〇 5, the zeroth diffraction class 11 〇 6 and the negative-diffraction 卩 ratio stage 1107. Compared with a single point source, the line source allows Very high light intensity is produced. The use of multiple added efficiencies and the full range of line source arrangements for reconstructing each part of the 3D scene enhances the effective light intensity. Another advantage is not the eve of the ray, the evening is A common light source (for example, after the tweezers that can be a part of the chopper) can produce sufficient dimming. B• Two pairs of organic light emitting diodes. Combination of body and optical address space light modulators In a more advanced embodiment, a tight fit of the combination of two pairs of organic light-emitting diodes and an optically-addressed spatial light view H can be used, in a continuous and compact manner: the amplitude of the change and her . Therefore, the complex number formed by the amplitude oil can be compiled in the transmitted light in a systematic manner. 23 200827953 This embodiment includes a first intimate combination of an infrared organic light emitting diode array and an optically addressed spatial light modulator pair and a second paired by an infrared organic light emitting diode array and an optically addressed spatial light modulator Close combination. The first pair modulates the amplitude of the transmitted light, and the second pair modulates the phase of the transmitted light. Alternatively, the phase of the transmitted light may be modulated by the first pair, and the amplitude of the transmitted light of the second pair may be modulated. The close combination of each of the infrared organic light emitting body arrays and the optically addressed spatial light modulators can be as described in Section A. The close combination of the two pairs of infrared organic light-emitting diode arrays and the optically-addressed space light H is separated by infrared ray, which absorbs infrared light without processing visible light. In the first step, the first-infrared organic light-emitting diode_write pattern is provided to provide amplitude modulation in the first-optical address spatial light modulator. In the second step 'Spray' second infrared money light-emitting diode _ writes with people to provide a view of the township in the second 'optical-style address space. Infrared filter prevents infrared leakage from the first-tight combination of a pair of infrared-organic light-emitting diode arrays and optically-addressed empty shame-corrected second-infrared-infrared-organic light-emitting diode array and optical addressing Sealing technology modulator. Infrared brain is also prevented from the second pair of red, surface organic & polar body array optical positioning space light modulation (four) tight combination, the line phase to the first - to the infrared organic light emitting diode Close-up combination of physical and optical addressing 24 200827953. However, the infrared filter transmits the closely combined visible light 'from the first pair of infrared organic light-emitting diodes to the optically-addressed spatial light tone _ as the second pair of infrared organic light-emitting two-spreading__ optically-addressed two-light tearing n The read wire in the close combination. The light sent by the second optical address* between the light and the light has been gambling at the amplitude, so that when the viewer observes the light emitted by the two-seven device, the observer has a three-dimensional image. The modulation of the complex value is promoted based on the white phase and amplitude modulation technique, and the organic light emitting diode display H and the optical address (four) filament changer both have high resolution. Therefore, the 'single embodiment can be used to generate a holographic image so that the viewer can see the three-dimensional image. In Figure 2, 'shows a real example. 20 is a device for providing illumination of a planar area and illumination is provided with sufficient stereotypes to produce a three-dimensional image. For example, in the US 2_ genus 71, an example of a large-area image hologram is an example. This type of device can be in the form of an array of white light sources, such as a cold cathode or a white light emitter on a flip line, where the focusing system can be tight, such as a lenticular array or micro. The lens array or the light source for 20 may be composed of red, green, and blue lasers, or red, green, and blue light-emitting diodes that emit sufficient coherent light. However, a non-laser source (e.g., a light-emitting diode, an organic light-emitting diode, a cold cathode fluorescent lamp) having a sufficient spatial homology of 25 200827953 is preferable. The shortcomings of laser sources, such as laser spots on holographic reconstruction, are more expensive, and the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The thickness of the elements 20-23, 26_28 may all be approximately equal centimeters or less. Element 21 may comprise a color filter array such that pixels of colored light (e.g., red, green, and blue light) are directed toward element 22, although color filters are not desirable if a colored light source is used. The tl piece 22 is an infrared organic light emitting diode array on a transparent substrate. The infrared organic light emitting diode array will cause each of the infrared organic light emitting diodes to emit light in the direction of the element 23 in parallel and conform to the light emerging from the unique corresponding color pixel. The 7-piece 23 is an optically-spaced space illuminator. Regarding the optical address spatial light modulator, the infrared organic light emitting diode array provides a write beam; the color beam emitted by the element U is a read beam. The component % is an infrared filter that transmits only visible light and interrupts the infrared light, so that the infrared light emitted by the component 22 does not affect the 27-inch optically-spaced optical modulator. Element 28 is a transparent, 'external line organic light emitting diode array. The infrared organic light-emitting diode array will enable the county-a mangrove light-emitting diode to emit in the tree's 27th fiscal direction first and parallel with the light from the only-to-turn color pixel. The optically addressed spatial aperture H 27, the infrared organic light emitting diode _ % provides a write beam; the colored beam emitted by element 26 is a read beam. Regarding the transmitted light, the component μ 26 200827953 tune = amplitude, 70 pieces 27 modulation phase. It is also possible to modulate the amplitude of the element 27, element 23: cycle = phase because the pupil from the infrared organic light emitting diode array on the transparent substrate 28 is incident on the direction of the 70 piece 26, the element 26 can absorb the infrared light, preventing the element 28 Light to optically located amulet 23. With this setting, the two organic light-emitting diodes _ 22 and 28 are placed in the opposite direction, and the opposite directions are in the real f. The two light-material addresses m and fine 23 and 27 can be placed in close proximity. The two-light address site is dependent on the $23 and 27 close to the dog to reduce optical wear and the pixel crosstalk caused by the beam knife ffij: when the wire-addressed spatial light modulators 23 and 27 are non-ringed, A preferred approximation of the non-overlapping lions of the colored light beams of the optically positioned light beam. The order of elements 27 and 28 of Figure 2 can be reversed 'but this is not considered to be an ideal miscellaneous realization of the setting of low crosstalk and high transmission targets between the colored light beams of the light-addressed spatial light U3 and 27. The element 2 can include one or two mirror optical films to increase the brightness of the display: such a film is known, for example, in the inner valleys described in US 5,056,892 and US 5,919,551. The τ block 20 may comprise a polarizing element 'or a collection of polarizing elements. The linear polarizing sheet is its towel-side. In addition, an example of a polarizing polarizer that can transmit a linearly biased state, and which reflects an orthogonal linearly biased state, such as is known, is described, for example, in US 5,828,. Another example is that a reflective polarizer 'transmits a circularly polarized state and reflects an orthogonal circularly polarized state - such a sheet is known, for example 27 27 as described in US 6, (8), 39s. Yj^ content. Element 20 can include a focusing system, a mirror array of microlens arrays. Element 2 已知 Known optical components. This focusing system can be compact, for example, can be included in other areas of backlighting technology, located at point 24, including the hologram _. Viewers, devices that can see $25 from the direction of 25 - some distance views

> In Fig. 1, the light emitted by the organic light-emitting diode arrays 22 and 28 is ideally collimated. However, the actual organic light-emitting diodes (4) may be light that is not collimated, such as Lambertian (completely diffused). When the light emission of the organic light-emitting body is not very collimated, the organic light-emitting diode can be as close as possible to the corresponding optically-spaced light modulator. In such a case, the intensity incident on the surface of the optically addressed spatial modulator will vary to approximately the square of the cosine of the incident angle. At 45. Or 60. The incident light will result in a intensity of only two-thirds of the normal incident light. 200827953 - or quarter--. Therefore, if the organic light-emitting diodes are filled with a sufficient interval of visible light pixels, and the optical age of the near-optical optical space is changed, the geometric effect will cause a significant change in the optical potential difference across the optically addressed space. Even in the case of the organic first diode::=Lambertian. The intensity of the incident infrared light can be between zero and the optically-addressed empty machine_point of the organic light-emitting diode. This can be expected to be low. However, if (4) the recording structure, the reduced contrast is acceptable. In the second case, the organic light-emitting diode array 22 and the light emitted by the germanium are ideally collimated. However, the light emitted by the actual organic light-emitting diode may be uncollimated, such as Lambertian (completely diffused) light. When the light emission of the organic light-emitting body is not collimated, the geometric light distribution of the organic light-emitting diode can be corrected by a φ_Bragg filter holographic optical element, for example, 阢5,153,670 collimation, or ratio It is difficult to make money and face. Figure VIII shows an example of a full-featured wire component in Prague. Eight sheds, 8G is an organic light-emitting diode array, 81 is a holographic optical element Bragg filter, and contains a Bragg flat, such as a Bragg flat © 84 ** 82 for a wire-type addressing (four) optical modulator. In the single-organic light-emitting diode 83 in the organic light-emitting diode array 80, the distribution of the emitted infrared rays is a distribution as indicated by 85. The light ray 86 emitted by the organic light emitting diode array 28 200827953 undergoes scattering in the holographic optical element 81 and is then incident approximately orthogonally on the optically addressed spatial light modulator 82. In this method, it is possible to improve the collimation of the infrared rays incident on the optically-addressed spatial light modulator 82. Another implementation is shown in Figure 5. 57 is a lighting device for providing illumination of the flat area _ field, and the illumination has sufficient brood to produce a three-dimensional image. An example of a full-image view of a large-area scene is provided in US 2〇06/25〇671, which is a side, a side. The device can be made in the form of a white light, such as a cold cathode ray or a (four) light-emitting diode, wherein the focusing system can be a compact 'such as a lenticular array or microlens. Array 5〇. Alternatively, the light source for 57 may consist of red, green, and blue lasers, or red, green, and blue diodes that emit sufficient tonal light. However, there is a full-fledged white light source (for example: light-emitting diode, organic light-emitting diode, cold cathode fluorescent lamp) ‘ 疋 佺 。. The shortcomings of the field source, such as the laser spot on the holographic reconstruction, * relatively expensive and all possible damage to the hologram display viewer or the holographic display I set the eyes of the assembly staff problem. The germanium element 57 may comprise one or two germanium optical films to increase the brightness of the display: a film of _ is known, for example as described in us 5, (d), 892 and us 5,919,551. Element 57 can comprise a polarizing element or a collection of polarizing elements. Linear 30 200827953 Polarized sheets are an example of this. Another example is a reflective polarizer that can transmit a linearly biased state and reflect an orthogonal linearly biased state - such a sheet is known, for example, as described in U.S. Patent 5,828,488. Another example is a reflective polarizer that transmits a circularly polarized state and reflects an orthogonal circularly biased state - such sheets are known, for example, as described in US 6, (8), 395. Element 57 may comprise other optical elements known in the art of backlight technology. The thickness of the pieces 57, 50_54 may all be about several centimeters or less. The component Μ can include a color filter filter such that the pixels of colored light (e.g., red, green, and blue light) are directed toward element 52, although a color filter is not required if a colored light source is used. The member 52 is an infrared organic light emitting diode array on a transparent substrate. The infrared-line organic light-emitting diode array will enable, for each-face color pixel, a light containing two infra-red organic light-emitting triple-spreads emitted in the direction of element 53 will be parallel and conform to them. The light emitted by the corresponding color pixel. The first infrared = organic light emitting diode emits a first wavelength of infrared light. The second lion infrared organic preparation light-polar body emits infrared light of the second wavelength, and the second wavelength is different from the first wavelength. The 7L piece 53 is an optically addressed spatial light modulator. Element 54 is another optical address space light modulator. Regarding the optical locating stray light modulator, the red illuminating diode array is connected to the nester #打·-, and there is a basket 丨 服 丨 冩 先 先 先 , , , , 51 51 51 51 51 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 . The optically addressed spatial light modulator 53 is controlled by the first wavelength of the two infrared wavelengths that are emitted by the organic light emitting diode array 52. The wire-addressed spatial light modulator 53 is insensitive to the first wavelength of the two infrared wavelengths emitted by the organic light-emitting diode array 52 and will emit the second of the two infrared wavelengths of the organic light-emitting diode array % Wavelength transmission. The optically addressed spatial light modulator 54 is controlled by a second wavelength of two infrared wavelength wipers emitted by the organic photo-polar array 52. The optically addressed spatial light modulator 54 is insensitive to the first wavelength of the two infrared wavelengths emitted by the organic light emitting diode array 52, or may utilize the optically addressed spatial light modulator 53 and/or The wire prevents the first-infrared wavelength of light from reaching the optically-addressed spatial light modulator 54, by its absorption, in the compact hologram generator 55's not necessarily required for the first-infrared, line> Long insensitive optically addressed spatial light modulator 54. Alternatively, a single organic light-emitting diode emitting two different wavelengths may be used. The relative intensities of the two different wavelengths are determined by a parameter such as the voltage across the organic light-emitting diode. Two different wavelengths of radiation can be controlled by time multiplexing. For transmitting light, element 53 is modulated in amplitude and element 54 is modulated in phase. It is also possible to adjust the amplitude of the element 54 and the element 53 to adjust the phase. With such a setting, the organic light emitting diode array 52 emits light having two different wavelengths, ensuring that the two optically addressed spatial light modulators 53 and 54 can be placed in close proximity. The optically-addressed spatial light modulators 53 and 54 are close to each other to reduce optical loss and due to beam divergence. 32 200827953 Correction string 1 problem. Optically-spaced spatial light modulators 53 and 54 are very large. A preferred approximation of the non-re-emission propagation of a colored light beam by an optically addressed spatial light modulator. . A three-dimensional image is viewed in a direction of 55 from a device that includes a percentage of the close-up hologram generator. The elements 57, 50, 5, 52, 53 . . . and ^ are configured to be physically connected (realally connected), each forming a layer of the structure, so that the body is an object of early -, system -. Physical connections can be direct. Or indirect 'if there is a thin intermediate layer, cover the film between adjacent layers. Physical connections can be limited to the correct arrangement of small areas that are mutually aligned, or can extend to larger areas or even the entire surface of the layer. The physical connection can be achieved by layer-to-layer bonding, for example by making the silk transfer transfer, the gorge forming a close-up hologram to generate benefit 55' or by any other means (refer to the outline manufacturing procedure section) ). ‘In the optically addressed spatial light modulator performing amplitude modulation, in a typical setting, the incident reading optical beam will be linearly polarized by passing the beam through a linear polarizer. The amplitude modulation is controlled by the rotation of the liquid crystal in the applied electric field, wherein the % field is generated by the photosensitive layer, affecting the polarization state of the light. In such a device, light exiting the optically addressed spatial light modulator passes through another linear polarizer, which reduces the intensity due to changes in the polarization state of the light, as it does when optically addressing the spatial light modulator. . 33 200827953 Performing phase modulation at optically-addressed spatial light modulators, unless they are in a sinusoidal linearly biased state, in a typical setting, the incident reading optical beam will pass the linear polarization through the beam. The slice is used to achieve linear polarization. Phase modulation is controlled by the application of an applied electric field, where the electric field is generated by the photosensitive layer, affecting the phase state of the light. In one example of phase modulation, nematic phase liquid crystals are used, the optical axis directions being fixed at intervals, but birefringence is a function of applied voltage. In the case of phase modulation, ferroelectric liquid crystal is used, and birefringence is fixed, but the direction of the optical axis is controlled by the applied voltage. In phase modulation implementation, using either of these methods, the output beam has a phase difference for the input beam that is controlled by the applied voltage. An example of a liquid crystal element that can perform phase modulation is a Freedericksz element arrangement in which an anti-parallel arrangement of nematic liquid crystals having a positive dielectric anisotropy is used, as described in US 5,973,817. Close combination of C· compact light source and electronic address space and light modulator. This is a close-knit combination of an electronic address space optical modulator and a fully coherent compact source that produces a three-dimensional image with proper illumination. In this embodiment, an electronically addressed spatial light modulator scaled light-f dense combination that does not require imaging optics is described. This combination provides a close combination of a light source 34 200827953 or multiple light sources, a poly-tn electronic address, and a non-essential beam splitter element. This combination (4) produces a three-dimensional image in the appropriate case. . In Figure 11 is an embodiment. 11〇 is a lighting device used to provide illumination for a flat area. The towel is a new one that can be used to capture a three-dimensional image. An example of a lighting device for a large area image hologram is mentioned in US 2006/250671. One example is shown in Fig. 4. An 11-inch device can be in the form of a white light source array, such as a cold-lighted or emitted light, which is shot on a poly-light system. The poly-lighting system can be mounted on a dense array, such as a lenticular array or micro. Lens array. Alternatively, the light source for 110 may be composed of red, green, and blue lasers, or a red and green-domain light-emitting diode that emits sufficient _ sexual light. Red, green and blue light-emitting diodes can be organic light-emitting diodes (OLEDs). However, it is preferable to have a full-size _ _ laser light source (for example, a light-emitting diode, an organic light-emitting diode). Laser light _ shortcomings, such as the phenomenon of laser spots on the holographic reconstruction, relatively more blame and all the damage to the holographic display of the viewer or the full-money set of red-handed eyes, etc. may be into question . The thickness of the king _ element 110 can be about 1/4 or less. In a preferred embodiment, 70 pieces of 11 () · 113 will have a total thickness of less than three centimeters in order to provide a sufficient _ sex close 35 200827953 light source tree 111 can be a color job, so that green and blue light) Like a 1-color plant (for example, red, color, β θ... to hand 112, although if a color light source is used, the component is an unnecessary one. The image is solved by the image generator m. ^. Located at point m from the close to the three-dimensional image., & Giant away from the viewer, can be viewed from the direction of ns / ^ L 1 1 / Λ - > can contain one or two 稜鏡 optics Membrane to increase the brightness of the display. Such a film is known, for example, in US 5,056,892 and US 5,919,551, the inner grain element 11 () may comprise a polarizing element or a collection of polarizing elements. An example is a reflective polarizer that conveys a hetero-biased recording, a neo-reflective orthogonal hetero-biased state, such as is known, for example, as described in still 5,828,488. Another example is that the sub-reflective polarizer can transmit a circular polarization. State, and reflecting orthogonal circular t-shaped biased states. Such flakes are known, such as those described in US 6, (8), 395. 70 pieces 110 may include other known in the art of backlight technology. Optical elements. Electronically addressed spatial light modulators are a type of spatial light modulator in which each element in an array of elements can be addressed electronically. Each element performs some effect on the incident light, for example To modulate the amplitude of the light it transmits, or to adjust the phase of the light it transmits, or to modulate the amplitude and phase of the light it transmits. An electronic address is provided in US 5,973,817. An example of a spatial light modulator, this example is Herr's electronically addressed spatial light modulator. The liquid crystal electronic space-space optical modulator is an example of an electronic address space optical modulator. The light is electronically addressed. The other example is that the components 110, m, m, and 113 are configured to be physically connected (realally connected), and each layer forms a structure, so that the whole is a single Object The physical connection may be direct or indirect. If there is a layer of the kerchief, the membrane shell connection covering the adjacent layer 1 may be limited to a small area ensuring a positive green arrangement, or may be extended. To a larger area, even the entire surface of the layer. The physical connection can be achieved by layer-to-layer hybrids, for example by using an optical transfer method to form f (four) full-sided generation n 115, or by any other means (Refer to the Summary Manufacturing Procedure section.) Figure 4 is a side view of a conventional technique showing the three focusing elements 1101, 1102, 1103' of the vertical focusing system 11〇4 in the form of cylindrical lenses arranged horizontally in the array. The beam that is nearly collimated with the horizontal line source LS2 passes through the focus of the illumination unit = the piece 1102 to the observer plane 0P as an example. According to Figure 4, many of the line sources (3), politics, and LS3 are arranged one above the other. The light emitted by each light source is charged in the vertical direction. 37 200827953 The injured room is the same as the horizontally (4) non-remaining. This light will pass through the transmission of the light-tuned U SLM. This light is due to the hologram __ ray modulator SLM components, only the diffraction in the vertical direction. Focusing element · Imaging light source (10) in the observer plane 〇p in the order of m (only one is useful). The light beam emitted by the light source (3) is an example of a focusing element which is measured only by the focusing system. In Fig. 4, a beam shows the first ray diffraction class, the zeroth class, and the negative 11⁄4 level 11〇7. The line system allows for very high light intensities compared to single-point sources. Efficient light intensity can be enhanced by using multiple lines of light source illumination with increased efficiency and for reconstructing each part of the 3D scene. Another advantage, not (four) laser 'multiple points _ (for example, after the city can be used - the miscellaneous slot) common light source can produce sufficient coherent light. Typically, the hologram display is used to reconstruct the wavefront in the virtual observer window. The wavefront is a call: something that an actual object will produce if it exists. When the observer's eye 7C is located in a virtual observer window that may be a virtual observer window (v〇w), he will see the reconstructed object. As shown in Figure 6A, the hologram display consists of the journal components: Light source 'lens, spatial light modulation 非 and unnecessary beam splitter 0 To help the spatial light modulation H and the compact light source that can display the holographic image, the combination of the single-light source and the single-figure sheet The lens can be replaced by a light-transfer and lens 38 200827953 array or lenticular array, respectively, as shown in Figure 6 6. In Figure 6b, the light source illumination space is fine-tuned n, and the lens is a county-to-age s-plane. The transformer encodes the holographic image and modulates the incoming wavefront so that the wavefront can be reconstructed in the virtual window. The non-essential beam splitter component can be used to count several virtual observer windows, for example -__left_ The virtual observer sees f and __ in the virtual view of the right eye. If a light source array and a lens array or a lenticular array are used, the light sources in the array must be separated to make it pass through the _ or the _ all lenses. Light at the same time The proposed observer window.

The device of Figure 6B is suitable for a compact design that can be applied to a compact hologram display. Such a holographic image is a system of action, such as in a line or personal digital assistant. Typically such a holographic display would have a mile or a few tiers of camp === bang ^ drink. The object element will be used in 1) the light source/light source array early-light source can be used for simple cases. If the observer moves, the spectator will be able to make adjustments so that the _ image can be made in the new position. (4), Kejia touches the window of the memorial, 39 200827953 is to track the mating component after the hybrid yarn n. A configurable array of light sources can be achieved by backlighting. In order to produce the line fine _,:;, = _ ¥ _, 矣肸 can s one, there are suitable pixels are switched to pass, up to the heart. _ light _ 杂 触 触 , , , , , 虽 虽 虽 虽 虽 虽 虽 虽 虽The spot light __ can be used with an array-through field containing a two-turn mirror. The line light __ is the lenticular array that contains the ^ mirror and is used. It is preferable to use an organic light-emitting diode display as an array of light sources. As a self-illuminating device, the light generated by the A portion of the liquid crystal display can be absorbed by a color such as a color device or a pixel that is in a non-perfect state, and can have a better skin-like condition. Electric effect. For example, a liquid crystal display may have an overall price advantage over an organic light-emitting device, even though an organic light-emitting diode display can provide light in a more efficient manner than a liquid-based display device. When an organic light-emitting diode display is used as a light-linked column, only the pixel switched to it needs to be in a virtual position, and an observation window is generated. The organic light emitting diode display can have a two-dimensional array of pixels or a -dimensionally arranged line source. The illuminating area of each point source or the i-degree of each line source needs to be sufficiently small to ensure that a full-image reconstruction of the target is provided. Similarly, an array of point sources is more suitable for use with a lens array comprising two-dimensionally arranged lenses. The line source (4) is more suitable for use with a lenticular array containing parallel-arranged round 200827953 cylindrical lenses. 2) 1 focus method · single lens, lens array or lenticular array Focusing tool imaging - one light source or multiple light sources to the observer plane. When the spatial light modulator is very close to the focusing tool, the Fourier transform of the information encoded in the spatial light modulator is in the observer plane. The focus tool contains one or several focus elements Φ. The position of the spatial light modulator and the focusing tool is interchangeable. ... For the close combination of the electronic address space optome and the full-fledged light source, a thin focusing tool is necessary: the refractive lens with a convex surface is too thick. Instead, a diffractive or holographic lens is used. A diffractive or holographic lens can have the function of a single lens, a lens array or a lenticular array. Such materials are present as a surface relief holographic product as provided by Physical Optics Corporation, T〇rrance, CA, USA. Or use a lens array. The lens array comprises two-dimensionally aligned lenses, each lens being assigned to a light source of the array of light sources. Another option is to use a lenticular array. The lenticular array comprises a one-dimensional array of cylindrical lenses, each lens having a corresponding source in the array of light sources. As noted above, if a source array is used with a lens array or a lenticular array, the light sources in the array must be separated such that light passing through the lens array or the lenticular array of all lenses simultaneously reaches the virtual observer window. 200827953 Through the lens, I don’t know what other lenses are different. The hologram of the space _ red coded is from the sub-image of each sub-image to the lens. The diameter of each lens must be large enough to ensure adequate resolution of the reconstructed object. It is possible to use a lens having an aperture that is almost as large as the typical size of the hologram coding region, as exemplified in the brain. That is to say, the aperture of each lens is one or several millimeters. 3) Spatial light modulator The full image map is coded on a spatial light modulator. Usually, the encoding of the hologram is made up of plurals: 纟幽的_. (4) The theory of the transformer should be able to modulate the amplitude and phase of the local light and light phase of each pixel by (4) Langwei. However, a general spatial light modulator can only modulate the amplitude and phase of the amplitude.

Modulate independently. b, for example, the code of a complex amplitude view arguing Wei Ke and the use of her code combination in combination with the Kha _ 娜 na code. Its disadvantage is that it requires three pixels to be programmed, and the reconstructed object is less bright. 42 200827953 = ^ sub-address space optical modulator has obvious edge characteristics, which will not lead, Wang Chen _ class in their diffraction pattern, can be used to transfer the cut-off hole by using the soft-line shirt An example of the τ ϋ method is the mathematical result of a Gaussian graph ==Γ__° (10) transition to a high 2 function. Shame, she transmits with a sharp cut-off aperture in her own transfer pattern. The diffraction of the beam intensity waveform function does not change except for the lateral scale parameter. An array of sheets of Gaussian transfer graphics can be used. When these are provided and arranged in the same way as the system with sharp cutoff in the beam transmission pattern, it will be possible to obtain a large number of reductions without a higher diffraction order. (4) System. The Gaussian device or the recording aperture filter will inhibit the diffraction processed product from being high. A high (four) s or soft aperture filter minimizes crosstalk between the virtual observer windows for the left and right eyes. 4) Beam splitter element The virtual observer window limits the periodic interval of the Fourier transform of the spatial light modulator coded information. Using the existing maximum resolution spatial light modulator, the virtual observer window is 10 millimeters in size. In some cases, this may be too small for applications that are not tracked in the hologram display. Spatial multiplex virtual observation Bay window is a solution to this problem: generating multiple virtual observers 43 200827953 _. In the case of the J1 in the workshop, the virtual fiber viewer window will be generated on the same day on the same position on the spatial light modulator. This can be achieved by a beam splitter. For example, the space group § on the group pixel encodes the information of the virtual observer window i, and the other group of pixels encodes the information of the virtual observer window 2. The beam splitter will distinguish the two sets of j-lights such that the virtual observer window i and the virtual observer window 2 will be juxtaposed on the observer plane. The virtual observer window 1 and the virtual observer window 2 can be configured to create a larger virtual observer view f. Duowei can also create a virtual window of the left and right eyes. In such cases, no seam juxtaposition is required, and there may be a gap between one or several virtual observer windows for the left eye and one or several virtual viewing S windows for the right eye. Be careful to look at the higher diffractive class of the window and not overlap with other virtual observer windows. A simple example of a beam splitter element is a parallax barrier comprising black stripes with a transparent area between the black stripes, as described in US 2 〇〇 4/223 〇 49. Another example is a lenticular sheet, as described in U.S. Patent Application Serial No. 4/223,. The other side of the beam splitter element is the lens array and the 稜鏡 shield. In a compact hologram display, it may typically be desirable to have a beam splitter element, whereas a typical 10 mil size virtual spectator window is only sufficient to provide one eye, which is not consistent with a typical viewer having two eyes and spaced apart It is 10 cm. However, time multiplexing can be used as an alternative to spatial multiplexing. In the absence of space multiplex, there is no need to use a beam splitter element. 44 200827953 Interwork can also be used in the reconstruction of color holograms. For spatial color multiplexing, pixels are grouped, with each group containing red, green, and blue color elements. These clusters are spatially separated in a spatial light modulator and simultaneously ride red, green and blue light. Each group will utilize a hologram encoding calculated for the color element corresponding to the target. Each group recreates the color elements of its holographic target reconstruction. 5) Time multiplex In the case of time multiplex, the virtual observer window will be generated at the same position on the spatial light modulator. This can be achieved by a position-time re-encoding spatial light modulator of alternating light sources. The alternate positions of the light sources must be such that the virtual observers in the observer plane are juxtaposed without seams. If inter- multiplex is fast enough, that is, the full period is greater than 25 Hz, the eye will see a continuously expanding virtual observer window. Multiplex can also be used to create virtual observer windows for the left and right eyes. In such cases, no seam juxtaposition is required, and there may be a gap between one or more virtual observer windows for the left eye and one or several virtual observer windows for the right eye. Such multiplexing can be space or time multiplex. Space and time multiplexing can also be combined. As an example, three virtual observers see _ is a lot of space to generate an expanded virtual observer for an eye. 45 200827953, this expanded virtual observer window is time multiplexed to produce a virtual view for the left eye, κ The spectator window and the expanded virtual observer window for the right eye. Care must be taken to ensure that the virtual spectator window of the virtual observer window is superimposed. ..., • Expanding the multiplex of the virtual observer window is more recommended than the re-encoding of the spatial light modulator, because it provides an expanded virtual observer window with _ observers and continuous changes in parallax. In simple terms, there is no re-encoding multiplex, which will provide repeated content in the expanded virtual observer window. Time multiplexing can also be used in the generation of color hologram reconstruction. For time color multiplexing of three color elements, they are encoded sequentially on the spatial light modulator. These three light sources # will switch simultaneously with the re-encoding on the spatial light modulator. If the repeat of the full cycle is fast enough, ie greater than 25 inches, the eye will see a continuous color reconstruction. 6) Undesirable processing of the sleek class If the larger imaginary observer sees t is a higher ray of the 'virtual observer window' that is spliced by the smaller virtual observer window, it may be in other virtual views. T, the staff window towel is still θ ' unless there is a step to avoid the problem. Take a scorpion> Every bit of the virtual observer window is located in the space light modulator, Ma Ma 46 200827953, the first zero-throwing class towel of the Fourier transform, the imaginary-weaving (fourth-level) May overlap with the virtual weaver window of _. Such overlap may result in disturbing 'if the unwanted image intensity exceeds about 5% of the required image intensity' & cranes that may change. In such cases, it tends to compensate or suppress higher diffraction classes. If the angle of the optical modulation II is constant, a fixed angular filter 3 can be used. This is not the case where the hologram display does not have a tracking function or the beam splitter element (e.g., beam pointing element) is located behind the spatial light modulator. The fixed corner filter can be a Bragg filter or a Perot Etalon. In the spatial light modulation H, an geometrical light intensity distribution with an unwanted diffraction level can be used. The Bragg filter H-optical optics is used for the correction of the light intensity distribution, as described, for example, in US 5,153,670. The Bragg filter holographic light + component can result in a different light intensity distribution than when the component is not used. Figure 7 shows the function of the Bragg Filter & holographic optics. In Figure 7, 7() is a spatial light modulator and 71 is a holographic optical element Bragg filter containing a Bragg plane, such as a Bragg plane 74. A single element 73 on the spatial light modulator 70 provides a diffracted light intensity distribution as shown. Light 76, which is diffracted by spatial light modulator 70, undergoes scattering in holographic optical element 71 and is then transmitted in a direction different from the original propagation 47 200827953 between 70 and 71. If the direction in which the light rays 76 are transmitted is between the 70 and 71 unwanted unwanted first-order diffracted light, it can be easily seen that the Bragg filter 71 successfully changes the light to a different direction so that it does not cause unwanted and may hinder viewing. The optically processed product of a typical viewer will be located approximately perpendicular to the direction of 70. An adjustable method for suppressing the diffractive class is mentioned in the patent application No. DE 10 2006 030 503. Mentioned is a liquid crystal layer between two coplanar glass sheets coated with a partially reflective coating. For each reflection of the coated beam, the beam is partially reflected and part of the ship. The dryness of the conveyor wire and the phase difference between them will determine whether it is pre-transfer or a shipbreaker, as described in the Fabry _ _ _ _ _ _ _ _ _ _ _ _ _ _. Given—dip length, interference and transmission will change with the angle of incidence of the beam. Given a - the amount of light propagation, the interference is simply changed from the crystal to the given light. Depreciation (4) plus follow-up control. Therefore, among all the restrictions of the Fabri's marriage rules, (4) the delivery characteristics are == age and money ___ the best level of transmission and the first class. In all the two classes of the Fabry-Pei-Dong and the higher class, the delay can help to transfer the specific order, the roots, or the reflection. 48 200827953 Space filter ϋ can be used in the selection of the diffraction class. The spatial filter can be placed between the spatial light modulation and the virtual virtual observer view t and contains transparent and opaque areas. These spatializers can deliver the desired diffractive class and block unwanted diffracting classes. These space filters can be _ or configurable. For example, the electronic addressing between the spatial light modulator and the virtual observer window can be used as a settable space. 7) Eye tracking In the close combination of the electronic address space light modulator with eye tracking and the well-matched type 2 light source, the eye position _ can be side observers' eyes or so The virtual observer window can be automatically set to 'make a bribe to see the hard-to-build objects.

The location of the personal digital assistant or the mobile phone's ::r eye does not help much. Everyone: (4) of the handheld device will tend to change the direction of the hand, Jane County Handle 49 200827953 The viewing state of the desire is as described in WO01/96941. Therefore, in such a device, the user's eye tracking is not required and the tracking optics that are complicated and not as tight as the scanning mirror are not required. However, eye tracking can be applied to other devices, as the device and power supply for additional requirements do not impose an excessive burden on the device. In the absence of tracking, the close combination of an electronic address space light modulator with a fully accommodating compact light source requires a large virtual observer window to simplify - display adjustment. A better virtual observer window size should be the size of the eye pupil size. This can be done by using a single-large virtual observer window using a small-pitch spatial light modulator, or by patching several smaller virtual observations of the spatially-spaced light. The position of the virtual observer window is determined by the position of the light source in the array of light sources. The eye position _ finder detects the position of the eye and the position of the mosquito light source to fit the virtual observer window to the position of the eye. This type of tracking is described in US 2 〇〇 18 Brain and US 2006/250671. . Another way, when the light source is in a fixed position, the virtual observer window: broken movement. The source tracking needs to be relatively insensitive to the change in the angle of the light source of the light source = the light modulator. If the light source is moved for the virtual observer window position, due to the possibility of abnormal light propagation in the tight combination, such a setting would be difficult for the stomach to be tightly combined with the spatial light modulator and the spatial light modulator. Such a solution = _ the last optical component of the nine bundles of 4 曰 to the component, will help. The beam lying component is shown in i/-Ten. This touch is directed to the _ end of the component. It can have optical properties for X and y tracking control and for z-tracking controllable lenses. For example, either or both of the beam directing elements of Figures 20 and _-10 can be applied to a single device. The beam pointing element is a (four) age component that can be used to ride a tree. The controllable refractive 7G member may comprise an array of recesses filled with liquid crystal, the liquid crystal being lost in an isotropic linear dipole susceptibility tensor matrix. Close the shape with a cymbal or lens. The electric field controls the effective folding of the liquid crystal. The electric radiation varies between components to produce a beam directing characteristic that varies between components. As shown in Fig. 20, electric φ : is applied between the transparent electrodes. The liquid crystal has a uniaxial refractive property, and can be selected such that its refractive index perpendicular to its optical axis is equivalent to the refractive index of the host material or matrix. The rest of the settings' are available from the conventional technology. The host material has an isotropic refractive index. If the optical axis of the liquid crystal is along the ζ direction of the lake, the appropriate electric field as shown in Fig. 20 applies a plane wave propagating along the Ζ direction, and when it passes through the beam to the element, there is no folding, because ϋ There is no refractive index change that is perpendicular to its Poynting vector. However, if an electric field is applied to the electrode so that the liquid crystal is tilted in the z-direction, the plane wave parallelized to the optical axis of 51 200827953 along the z-direction side, when it passes through the element, will encounter the most = paste_ The possible refractions:: degree? Between these two extreme examples, adjustment can be made by selecting the appropriate electric field applied to the host material. If the pit is braided and not mirrored, the __ tow is pointed. Lutu-Ten-display does not point to a suitable prism shape for the beam. If the optical axis of the liquid crystal is aligned in the ^ direction, as shown in Fig. 20, the plane wave 'propagating along the Z direction' does not cause refraction when it passes through the beam pointing element because it It does not encounter any refractive index changes in its direction of polarization. However, if the field of electronics is such that the liquid crystal axis of the traverse electrode is perpendicular to the z-direction, the plane wave propagates z is biased parallel to the most refraction of the light-stained experience because it beam 彳a to the component 'because it experiences The most probable refractive index secret provides its wavefront vector (P〇ymingvector). * If the encapsulation field is on the electrode 'the optical axis of the liquid crystal is perpendicular to the z direction, •'.

The degree of refraction will be adjusted between the two extreme examples of 14 by selecting the appropriate electric field applied to the host material. 52 200827953 8) Example material, silk = 4 electronically-positioned Lang Guang modulation is full of ambiguity. _ Combination example, this combination can produce - dimensional image in the appropriate situation - can be set in the personal number Or mobile phone towel. The close combination of the electronic address space optical modulation n and the sufficient _ series _ vehicle includes an organic light emitting diode display as an array of light sources, and an electronically addressed spatial light modulator disk lens array, as shown in FIG. Depending on the location requirements of the virtual observer window (represented by 〇w in Figure 12): a specific pixel in the _light-emitting diode display. These pixels illuminate the electronically addressed (four) _ variator, and the lens is imaged by the lens at the observer's planar lens I1 at least - the transilin is activated in the organic light emitting diode display. In Wei mosquitoes, the ulnar nucleus is small, and if it is like a prince, it can be thinned with a virtual touch window with lateral increments. This is quasi-continuous. The organic light-emitting diode image surface has a partial space-sex light source. Partial homology produces a modulo-reconstruction of the target point. At a given size, if the pixel width is 20 microns, a (10) micro-transverse mode _ reconstruction will be produced at a target point that is millimeters from the display. The resolution of the cake in the human sense is 53 200827953 ^ The lens of the lens is not mirrored, and there is no homology. The need for coherence is _ to each lens of the lens_. Therefore, the degree of riding of the reconstructed target point is determined by the lens_off distance. For the human visual system, the typical transmissive distance will be the silk class to ensure the resolution of the Newton. If the organic light-emitting diode _ distance is 2 〇 micrometers, this means that the ratio of the lens pitch to the organic light-emitting diode pitch is 50: If each lens has only a single organic light-emitting diode is illuminated, this wire is 5 〇 λ2 = 2, 5 () () money shines two bells, only one organic light-emitting diode will be bright. For this reason, this display is a low power display. The difference between the holographic display and the light-emitting diodes shown here is that the former concentrates on the light of the ducks, and reads the county to the % sphericity. The traditional organic light-emitting diode _ shows 1! Real _!, _ ed / mA2 hair, (inventor in the calculation), and in fact, in practice, the simple machine (four) two can achieve WOOOcd / ml light Several times the degree. The virtual observer window is a diffractive class that limits the Fourier spectrum of the encoded information in the spatial light modulator. If the pixel pitch of the spatial light modulator is, and two pixels are needed to encode a complex number, ie if the phase modulation is in the electronic address space, the code is on the surface of the virtual observer window. It has a width of 10mm wide. The virtual observer window can utilize space or time multiplexes to piece together several virtual observer windows into an expanded virtual observer window. In the case of multiplexing between * 54 200827953, additional optical components such as beam splitters are required. The reconstruction of the shirt color hologram can be realized by time multiplexing. The red, green and blue pixels of the color organic light emitting diode display are successively activated by synchronous re-encoding of a spatial light modulator having an hologram of the red, green and blue optical wavelengths. The display may include an eye position detector to detect the observer's eye position. The eye position detector is connected to a control unit that controls the pixel activity of the organic light emitting diode display. The calculation of the hologram encoded on the spatial light modulator is preferably performed by an external encoding earlier because it requires higher computational power. The display data is then sent to • Personal Digital Assistant or Mobile Phone to display a three-dimensional image of the full image. For the example of money service, a 2.6 inch screen ruler made by Sany0 (rtm) Epson (RTM) g g Devices Corporation of Japan can be used to call the XGA liquid crystal display electronically positioned spatial light modulator. The sub-pixel pitch is 17μπι. If this is used for the construction of the red, green and blue holographic display, the amplitude of the hologram is used, and the code is changed. In the distance from the electronically-spaced spatial modulator 〇.4m, the observation window is based on the leaf. The difference is wide. For the case of monochrome, the viewing window is 4mm wide according to the calculation 55 200827953. If the same setting is used, but the phase modulation of the 2 phase encoding is used instead, the viewing window is calculated to be 6 mm wide. If the same settings are used, but the phase modulation of the Kinoform encoding is used, the viewing window is calculated to be 12 mm % °. In addition, there are other high-resolution electronic addressing spatial light modulators. 10 Seiko (RTM) Epson (RTM) Corporation of Japan has published a monochrome electronic address space optical modulator, such as a D4:L3D13U 1·3 inch screen size with a 15μm pixel panel. The company also published the same type of panel D5: L3DG9U_61GGG, with a 9-inch screen size and 1 () μηι pixel pitch. On the 12th of December, 2006, the company announced that the same type of panel I3D07U-81G00' has a 7.7 inch screen size and a pixel spacing of 8 inches. If the D4:L3D13U 1.3 inch panel is used to construct a monochrome holographic display and uses a full-rubbed Burckhardt amplitude modulation code, the distance from the electronically addressed spatial light modulator is 0.4m. The virtual observer window can be calculated as 5 6 job width ^ * D. The close combination of the paired electronic address space light modulators can be in a different and tight manner in another implementation, _ two electronic The combination of the address space and the fine Wei comes to the amplitude of Xiaguang and her. Therefore, the complex amplitude and phase can be encoded in the transmitted light one by one. ^ 56 200827953 This implementation contains two electronic framing FF s. The first electronic address (4) _ Wei machine transmits the Yang amplitude, and the second electronic address space optical modulator modulates the phase of the transmitted light. It is also possible to modulate the phase of the transmitted light by a first electronically addressed spatial light modulator, and the second electronically addressed spatial light modulator modulates the amplitude of the transmitted light. Each of the electronically addressed spatial light modulators can be as described in section c. In addition to the _ two electronic address space light modulators, • the overall configuration can be as described in section c. Any combination of any of the other two types of Xuan-style addressing _ Wei modulation characteristics of the amplitude and phase (four) age machine is possible. In the first step, the 'first-electronic address spatial light modulator uses pattern coding' to perform amplitude modulation. In the first step, the second electronically-spaced space light tone' and the fine-grained light have been applied to the axis, so that when the observer observes the two electronic addresses of the device, a three-dimensional image can be observed. image. The light emitted by the device is based on "she she __ 智 敏 敏 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Figure 13 is an embodiment. 130 is a lighting device for providing illumination of a planar area where it is sufficient to produce a three-dimensional image. As mentioned in US 2006/250671 - for large Examples of illumination and illumination devices for regional image holograms, an example of which is shown in Figure 4. The device as in (10) can be in the form of an array of white light sources, such as cold negative silk or light emitted by humans. White light - polar body 'where the focusing system can be tight, such as a lenticular array or micro lens (four). Or 'secret 13G light source can be composed of red, green lasers, - or send a full _ sexual lying Red, green and blue light-emitting diodes can be formed. Red, green and blue light-emitting diodes can be organic light-emitting diodes (OLEDs). However, non-laser light sources with sufficient space (eg, light-emitting diodes) Polar body, organic light-emitting i-pole, ^ cathode fluorescent lamp) is better. The lack of laser light source It may be a security problem such as causing a laser spot on a holographic reconstruction, being relatively expensive, and causing damage to the holographic display viewer or the eyes of a holographic display assembly worker. _ Component 130 may include One or two 稜鏡 optical films to increase the brightness of the display: such a film is known, for example, as described in US 5,056,892 and US 5,919,551. Element 130 may comprise a polarizing element or a polarizing element. A set of linear polarizing sheets is one of them. Another example is the anti-transportable - linearly polarized state 'and the orthogonal orthogonally biased state - such a sheet is known', as described, for example, in US 5,828,488. Content. Another example is the reflective partial W, which can transmit a circularly polarized hearing, and the reflection orthogonal circle 58 200827953 shape-biased state - such a sheet is known ^ as described in the still ^ (8) 'milk The component 13G may comprise a poly-reduction system, which may be compact, such as a lenticular array or a microlens array. The component 13 may include other known in the art of backlight technology. The thickness of the element 130 can be on the order of a few centimeters or less. In a preferred implementation, the thickness of the element 130·134 is all less than 3 cm to provide a tightly compacted compact-dense source. Element m can be a color filter _ such that pixels of colored light (e.g., red, -, green, and blue light) are directed toward element 132, although a color filter is not required if a colored light source is used. Element 132 is Electronically-positioned spatial light modulator. 7L piece of electronically-spaced spatial light machine. Element 134 is an unnecessary beam splitter element. For transmitting light, element 132 is modulated in amplitude and element 133 is modulated in phase. The amplitude is modulated by element 133 and the phase of element 132 is modulated. The proximity of the electronic phantom space modulators 132 and 133 can reduce the optical loss and the pixel crosstalk caused by the beam ^: when the electronic address space light modulator says that 133 is very close A better approximation of the non-heavy $-touch of the colored light beam by the on-the-job addressing. A viewer located at a point (3) some distance from the farm including the hologram generator 136 can view a three-dimensional image from 136. ^Parts DO, 13 Bu 132, 133, and 134 S are configured to be physically connected (realally connected to 59 200827953). Each layer forms a structure, so that the whole is a single, unified object. The physical connection can be direct. Or indirect, if there is a thin intermediate layer, covering the adjacent layers. Physical connections can be made in areas that ensure proper alignment: or can extend to larger areas, even the entire surface of the layer. The physical connection can be realized by layer-to-layer connection, for example, by means of optical transmission of glue.

In order to form a compact holographic 136, or to incorporate any of the other parts of the test procedure. U • At the 1st sub-change record, in a typical setting, the incident optical beam will be linearly polarized by passing the beam through a linear polarizer. The amplitude is controlled by the Weijia electric liquid crystal thief transfer, and the application of an electric field affects the biased state of the light. Face_device towel, _ electronic address space light modulation n light will pass through another linear polarizer, which can reduce the intensity due to the polarization of the light's biased state as it passes through the electronically addressed spatial light modulator Same time. In the case of Lang Guangguan H, she performs her tuning, and they are in a defined linearly biased state. In a typical setting, the human reading optical beam will be achieved by passing the beam through a linear polarizer. Linearly biased. The phase modulation is caused by the electric field's response, and the electric field will illuminate the _ recording state. In one example of her modulation, the use of nematic phase liquid crystal 'the optical axis direction is definite, but birefringence is a function of the applied lag. In the case of phase modulation, the use of ferroelectric 200827953 ϋ liquid 曰 a ' birefringence is fixed, but the direction of the wire is controlled by the applied voltage. In the implementation of the phase, in any of these methods, the output beam will have a phase difference with the input beam that is a function of the applied voltage. An example of a liquid crystal element that can perform phase modulation is a Freedericksz element arrangement in which an anti-parallel arrangement region having a positive dielectric//directional nematic liquid crystal is used, as in Us 5, 9 The content described in 817. A compact combination for compact hologram display, consisting of two electronic (4) light taps combined in a small or minimal separation. A preferred embodiment is that the two spatial light modulators have the same number of pixels. Because the two electronically addressed spatial light modulators are not equidistant to the observer, the pixel spacing of the two electronically addressed spatial light modulators may need to be slightly different (but will still be about the same) to replenish The impact of the distance on the observation of the sacrifice. The light that has passed through the pixels of the first spatial light modulator φ passes through the pixels corresponding to the second spatial light modulator. Therefore, light is modulated by two spatial light modulators and complex amplitude and phase modulation can be achieved independently. As an example, the first spatial light modulator performs amplitude modulation, and the first spatial light modulator performs phase modulation. Similarly, any combination of the other two spatial light modulator modulation characteristics that are equivalent to independent modulation of the amplitude and phase is possible. It must be noted that the light passing through the pixels of the first spatial light modulator can only pass through the 61 200827953 -: light cap! The pixel corresponding to I. If the light from the first-space light modulator pixel is emitted by the second spatial light modulator, the crosstalk may cause a problem of image quality degradation. Here, a possible method of minimizing crosstalk problems is provided. As will be apparent from the conventional techniques, these methods can be equally applied to the Part B embodiment. ❿ (4) (1) M - The easiest way is to directly adjust the two spatial light k after the adjustment of the pixel to connect or glue. In the pixels of the first-space light modulator, there may be a wrap-around that causes the spread of the cake. The separation between the spatial lighters must be sufficiently thin to achieve acceptable privacy for the crosstalk between adjacent pixels of the second spatial thinner. Lift-side, the spacing of two electronically addressed spatial light modulators with a pixel spacing of 1 〇, must be less than or equal to 1 (Μ()() μιη level of manufacturing space ray is almost impossible to achieve Because the thickness of the glass cover is 1mm. Of course, the 'M3" method that enables a thin separation layer between the spatial light modulators is recommended by Na Na. Gu outlines the manufacturing method described in the 'Private-Sequence' to produce a device that includes a small or minimal electronic address space light modulator with two smokers. Figure 14 shows the diffraction calculation of the slit 10μηι width. The resulting Fresnel diffraction data graph changes the distance from the slit in the two-dimensional model, the vertical axis is slit(z), and the horizontal axis is lit(x). The uniform slit is located on the X-axis. Between and, z 62 200827953 is zero micron. The optical transmission medium is used to obtain a refractive index of 1.5, which is a typical medium for compact devices. The selected light is red light with a 633 leg vacuum wavelength. Green and blue The wavelength is smaller than the red light, so for the calculation of red light, in three colors red, And the blue towel's show the strongest diffraction effect. You can use par_ric Technology (RTM) c〇rp., Needham, MA, USA.^^. MathCad (RTM) software pure line calculation. It is a function of the distance from the slit in the width of the slit ΙΟμιη on the center of the seam. In the distance from the slit 2〇_, the figure is shown in the range of 9G%_degree in the narrow _ 1()_ wide Therefore, in this two-dimensional model, less than the state's pixel intensity will be incident on each adjacent pixel. This is the result of the zero-width _ track between the pixels. Actually the pixel_boundary width is greater than the material. Therefore, the crosstalk is in the real system ^ lower than the result calculated here. In Figure 14, the Fico diffraction pattern is close to the slit, for example, the slit 50 is handsome, and the new one is tested in the high hat function of Wei. Therefore, there is no wide diffraction characteristic close to the slit. The wide diffraction characteristic is the characteristic of the far-field diffraction function of the high-hat function, which is a known function of _% job d. The wide junction feature can be Figure 14 shows an example of the distance slit class. This indicates that the scale effect can be _ electronically addressed. The inter-lighting setting is close enough to control 'and the two electronically-spaced spatial tones _ set a very close one advantage is the function of the diffraction table, which will change from far-field to more efficient ^ Close to the axis perpendicular to the slit __ style. The advantage is contrary to the idea of the application of the king image technology, the conventional technology will tend to think that when the light passes through the space 63 200827953 light small device, it will cause strong , large and inevitable diffraction effects. Therefore, the conventional technique does not have the motivation to bring the two spatial light modulators together. It is expected that such a way will inevitably occur and be severely caused by the diffraction effect. Pixel crosstalk problem. Figure 16 shows a contour plot of the intensity distribution with a Φ function of the distance from the slit. The plot of the contour is on a logarithmic scale, not a linear scale. The " ten contours are used, all including a range of 100 intensity factors. For the slit width of lOjiim, the boundary of the intensity distribution is clear in the range of about 5 〇 μηη from the slit. In a further embodiment, the pixel aperture region of the first electronically addressed spatial light modulator can be reduced to mitigate the crosstalk problem in the second electronically addressed spatial light modulator. 0 (2) The second method is A lens array is used between the two spatial light modulators, as shown in Figure 17. A better approach is to have the number of lenses equal to the number of pixels in each spatial light modulation. The spacing of the two spatial light modulators and the spacing of the lens arrays can be slightly different to compensate for the observer's distance difference. Each lens images the pixels of the first spatial light modulator to the corresponding pixels of the second spatial light modulator, as shown by the plurality of light beams 171 in FIG. It is also possible that light will cause a string of sounds through adjacent lenses, as shown by a large number of beams 172. If its intensity is low enough, or if its direction is sufficiently different to make it impossible to reach the virtual observer window, it can be ignored. The numerical aperture (NA) of the master lens must be large enough to image a pixel with sufficient resolution. As an example, for a resolution of 5 μm, a numerical aperture (ΝΑ) of about 0.2 is required. This also means that if it is assumed to be a few optical, if the distance between the spatial light modulator and the lens array is ΙΟμηι, the maximum distance between the lens array and each spatial light modulator is about 25 μm. It is also possible to assign several pixels of each spatial light modulator to one lens of the lens array. For example, the four pixels of the first-space optical modulator are grouped, and one of the lenses in the lens array can be imaged to the second spatial light modulator by one of four pixels. Group. The number of lenses of such a lens array will be the number of pixels per __ towel. This allows for higher numbers = • hole (four) lenses, which can be used to obtain high resolution silk pixels. The two methods of the younger brother are to reduce the pixel aperture of the first-electronic space to lightly change the crying. From the viewpoint of diffraction, the second spatial light modulator is determined by the pixel aperture width D and the winding (4) of the area illuminated by the pixels of the first-empty fuel conditioner, such as the pixel width of the electronic address space. The needle continues. In Fig. 10, 2008, 2008, the distance between the 'd' electronically-addressed spatial light modulators, fffj W is the distance between the two first-P-level diffraction minimums, which occurs at the zeroth class maximum. Any of the defamations is delineated as Fraunh〇fer, or a reasonable approximation of Fraun and Fiji. Reducing the aperture visibility D - in terms of reducing the direct projection of the central portion of the illumination area • (4)' is shown by the dashed line in Figure 18. On the other hand, the diffraction angle is increased in accordance with the diffraction angle being proportional to 1/0 of the Fraunhofer diffraction. This increases the width w of the illumination field in the second electron 歧 空间 space _ 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 、 In the Fron and Fiji diffraction methods, giving the separation d, D can be determined, and using the equation w = D + 2_ to minimize w, which is the first of two from the Fraun and Fiji diffractions. The distance between the order minimums is derived. • For example, if 1 is 0·5 is 1, d is ΙΟΟμηι and w is 20|im, D_ is the minimum value of ΙΟμπι. However, in this example, the Fran and Fiji methods may not = yes - a good approximation, this example illustrates the use of the distance between the electronic neon space light modulation ^ to control the Flang and Fiji diffraction modes. The principle of the diffraction process. (4) The fourth method uses a fiber optic panel to image the pixels of the first spatial light modulator to the pixels of the second spatial light modulation H. The fiber optic panel is made up of two-dimensionally aligned parallel fibers. The length of the fiber and therefore the thickness of the panel is typically a few millimeters. The length of the surface of the surface of the board is as long as several shots. As an example, the spacing of the fibers can be _. Ed Cong nd 0ptics Inc. of Barringt〇n, - Zhiqing said that there are fiber optic panels such as fiber spacing. Each fiber optics directs light from one of its sources to the other end. Therefore, at the end of the panel, the image is transmitted to the other end, which has high resolution and is not satisfactorily; Such a panel can be used as two blade layers such as the light modulator 1 as shown in Fig. 19. Multimode fiber is preferred over single mode fiber because multimode fiber is better than single mode fiber. #域核_狮 ratio and liquid crystal _ 斤 射 是 是 是 是 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆 姆In two spaces, the light has an extra glass cover. The polarizer, the cymbal and the alignment layer are directly connected to the fiber optic panel. Each of these layers is very thin, which is a level of 1 〇 μΐη. Therefore, the liquid crystal (LC) layers LC1 and LC2 are in close proximity to the panel

The light that passes through the first spatial light modulator pixel is also directed to the pixel corresponding to the second spatial light modulator. This minimizes the crosstalk of the pixels. The panel transmits the light distribution at the output of the first spatial ramp to the input of the second spatial light modulator. Ping :. Each pixel should be at least one domain.

The element 104 may comprise a polarizing element or a collection of polarizing elements. 68 200827953 Linear polarizing sheets are one of them. Another example is reflective polarizers, which can transmit - 偏 biased state 'and reflect orthogonal tortographic states. Such sheets are known, for example in US 5,828, the content described in the other example is a reflective polarizer 'transportable - one _ biased state, and the reflection of the orthogonal circular polarization state. Such a system is known 'for example, in US6, m , 395 in the content of the description. Components Other optical components known in the art of backlight technology may be included. The thickness of the component may be approximately several centimeters or less. The component may include an array of color filters such as red light (eg, red The pixels of green and ambiguous are directed to element 1() 2, although color is not required if a color source is used. Element 102 is an electronic address space optical modulator that encodes phase information, such as a Freedericksz component. The component 1〇3 is an electronic φ-newspace space for encoding amplitude information, for example, in a liquid crystal display device on the front side.

The order of encoding the amplitude and phase can be reversed as shown in Figure 10. 69 200827953 A viewer located at point 106 from the apparatus including the close hologram generator 105, which can view a three-dimensional image from the direction of 105. The elements 104, 1 〇〇, 1 (H, 1 〇 2 and 103 are configured to be physically connected as previously described so as to form a compact hologram generator 105. E. Components contain - pair or two pairs of organic Luminous two-pole optical-addressed spatial light modulator combined with one or two electronically-addressed spatial light modulation (four) tightly combined 'and large-magnification three-dimensional image display with target holographic reconstruction

Figure 24 shows a close-knit combination of a component or a pair of two or two pairs of organic light-emitting diodes and an optically-positioned Langguang H combination or one or two electronic addresses*. Large magnification 3D with target holographic reconstruction. The components of this health include a close combination of the Guangxia axis's close-conformity compact light source (eg, as described in sections A, B, c, and D). Such a combination can be used in appropriate lighting conditions. Observing the stomach vision ^ in the ^ twenty-four marked OW) towel produces a visible triple image, this 妓 component can be integrated in a personal digital assistant or mobile phone. As shown in Fig. 24, the close combination of the modulator and the tight-to-close tight-source includes the light source inter-modulation II and the lens array. The spatial light modulator in Figure 24, the combination of the pair of two or two pairs of organic light-emitting diodes and the optically-addressed space fine (4) person = one or two electronically-positioned spatial light modulators , or 200827953 light diode and fresh-type address miscellaneous _ Wei Wei and Lai - an address space optical modulator. In a simple _ sub, the light source _ can be formed in the following manner. A single light source, such as a monochromatic light-emitting diode, is placed in close proximity to the aperture array to allow it to illuminate the aperture. If it is a slit of the dimension, the light transmitted by the general slit will be shaped into a light source of the array. If the aperture is a circle of a two-dimensional array, the illumination set of the circle is a light source that forms a two-dimensional array. A typical aperture width will be approximately 20 sec. Such an array of light sources is suitable for the generation of an observer window for one eye. In Fig. 24, the light source array is disposed at a distance from the lens array u. The array of light sources can be a light source of one element of Figure 1, and can optionally include element 11 of Figure 1. Specifically, each of the light sources in the array of light sources is located at a distance from the lens u corresponding to the lens array. In a preferred embodiment, the wire array is parallel to the plane of the lens array. The spatial light modulator can be located at the lens array. The distance between the virtual observer window and the lens array is u. The lens in the lens array is a concentrating mirror. The focusing length f is given by f = 1 / [1/u + i / v]. In the more limited addition, the value of V is in the range of 3 〇〇 mm to 6 〇〇 mm. A more preferred embodiment ♦, V is approximately 400 mm. In a preferred embodiment, the value of u is in the range of l 〇 mm to 3 Gmm. In a more preferred embodiment, u is approximately a melon. The amplification factor M is determined by v/u. Μ is the light source modulated by the spatial light modulator, 71 200827953 in the virtual observer _ magnified _ prime. In the preferred embodiment, the value of Μ is in the range of 1 〇 to 6 。. In a more preferred embodiment, Μ is approximately 20. In order to achieve the magnification of the 匕, and to have a good holographic image quality, an array of light sources and a lens array that are accurately aligned are required. In order to maintain accurate alignment and maintain the same distance between the arrays of light source array discs, the device components need to have strong mechanical stability until the component's useful life is exceeded. Φ 6 Virtual Observer windows can be traceable or untrackable. If the virtual observer sees S as traceable, the virtual light source window will be inspected and the specific light source in the light source array will be activated. The illuminating light source and the spatial light modulator are imaged by the lens array to observe the pupil plane. In the light transfer, at least one system is activated for each lens in the lens array. The memorial is continuous. If u is 20mm and V is 400mm, if the pixel pitch is 2〇μπι, it can be traced to • Virtual observer window with 400μιη lateral increment. Such tracking is quasi-continuous. If u is 20 mm and ν is 400 mm, f is approximately i9 mm. The light source in the array of light sources may only have partial spatial homology. Partial homology leads to fuzzy reconstruction of the target point. If u is 20_ and ν is 4〇〇mm, if the source width is 20μπι', the reconstruction of the target point of 100mm from the display is provided with a lateral blur of ΙΟΟμπι. This is sufficient for the resolution of the human visual system. 72 200827953 The position of light that passes through a single lens in a lens array does not need to have any significant mutual sprinkling. The need for coherence is limited to each single lens in the lens array. The resolution of the reconstructed target point is determined by the pitch of the lens array. A typical lens pitch will be a 1 mm level to ensure that the virtual viewing window for the human visual system is the Fourier frequency of the encoded information in the spatial light modulation. If the pixel spacing of the transformer is 1G division, and you need the two-code encoding—the number of tilts, that is, if the phase is _weizi-type address ^m is used, the virtual observer window will have a width of lGmm at the wavelength of the leg. The width. The virtual observer window can multiplex space or time to piece together several virtual observer windows into an expanded virtual observer window. In the case of * (4) work, additional optical components are required, such as silk penny. In the part: 4 Tian said a good way to defend, these multi-wei methods may also be implemented in the secret case... Color holographic reconstruction can be achieved by time and multi-function.

The eye position detector is connected to a control unit that controls the activation of the light source in the array of light sources. The calculation of the hologram image encoded on the two optical faders is preferably performed by an external coding unit because it requires higher computational power. The display data will then be sent to the φ number of assistants or mobile phones to display the three-dimensional image produced by the hologram. For the example on Bay, you can use Sanyo (RTM) Epson (RTM)

2·6 inch screen size manufactured by Imaging Devices Corporation of Japan XGA LCD electronically positioned space light modulator. The pitch of the sub-pixels is 17 μm. If this is used for the construction of the red, green and blue hologram display, the amplitude modulation code of the hologram is used, and the φ window is calculated to be L3 mm wide at a distance of 4 m from the electronic address space modulator. In the case of monochrome, the viewing window is calculated according to - 4mm wide. If the same setting is used, but the phase modulation of the 2 phase encoding is used, the wheat viewing angle is 6 mm wide depending on the difference. If the same setting is used, but the phase modulation of the Kinoform encoding is used, the viewing window is calculated to be 12 mm wide. There are still other high resolution electronic address space light modulators. Seiko (RTM) Epson (RTM) Corporation of Japan has published a monochrome electronic address 74 200827953 Space light modulation n, such as D4: L3D13U 13 panel with a screen size of 15 μm.

Other cars can be displayed on the display in three dimensions, such as speed, temperature, and minute-by-minute information. Satellite navigation information can be displayed in three dimensions on display H. All the information on the display can be divided into three dimensions. The size of S is limited by the dependence interval of the Fourier plane towel. If the organic light emitting diode display or the electronic address space light modulator is used, (10) The prime spacing is close to 1 () μιη ' then to the visible (10) visible light, at 〇mm, according to the encoding used by the hologram spatial light modulator, the width of the virtual observer window (V0W) is approximately It is 1 to 25_. This is wide enough for a 'eye'. For the other second virtual observer, it can be established by spatial or temporal multiplexing in the inter-ratio. In the absence of less tracking, in order to see the best three-dimensional image, the observer must rotate or move the device and / or his own position, so that his eyes can be in the virtual observer window, and record the most System transfer. The way in which the virtual observer windows are patched together makes it easier to adjust the position and orientation of the display device. Two or three virtual observer windows can be juxtaposed in the χ- and v_ 77 200827953 directions so that the virtual observer window can cover a larger area. The way to piece together can be done by space or time multiplexing, or a combination of space and time multiplexing. In time multiplex, light is projected onto the virtual observer window in time. If the virtual observer window has a different space, the optical modulator must be reprogrammed. In spatial multiplexing, the content of the different virtual observer windows is encoded in the spatial fineness n at the same time 'but in different areas of the spatial light modulator. The beam splitter splits the light from the spatial modulator into different virtual observer windows. A combination of space and time multiplexing can be used. The size of the screen of a hand-held three-dimensional display device typically used for mobile phones or personal digital assistants is between the fineness of the slave and the camera. The full-image display can have a screen size as small as one centimeter. The three-dimensional image display device can switch to display a two-dimensional image, for example, by displaying an image to each of the viewer's eyes. ",,,", and Figure 3 show the implementation of a three-dimensional image display that includes one or two pairs of intermodulation or a thin one? == diode and optical address space combination For example, if the device equipped with the device is a mobile phone displayed on the screen area 3i, another 3D image of your field is displayed on the phone. The user can make a call. The mobile phone has an assembly 78 200827953 antenna % ' for mobile communication. In other embodiments, the antenna can be located in the main body of the mobile phone. The mobile phone is equipped with two cameras 33 and 34, respectively ^ Record user Wei and right eye _ image. Silk and right _® image contains stereoscopic image. Mobile phone 30 is equipped with digital and "*,, and "#" symbol button %, and other function buttons 36, For example, in the tomb of the tomb, the yang yang 他 * he moved on the screen as an early towel, phase or start to close:,. The indications displayed on the side such as "〇N" "〇FF" or "2,, can be reversed:" to prevent both parties from making a 3D video call, when watching the other party _: Yes. In use, the eyes of the two viewers are preferably coplanar with the two cameras and the corrections, and the face of the maker is in the position of (4) straight to the screen area 3!. This makes it possible to confirm the (four) frequency 33 and 34 to record the parallax in the plane containing the viewer. The viewer's head is pre-determined for displaying (10) the most reasonable weaving position so that the two cameras 33 and 34 can obtain the most desirable image quality of the viewer's head at this location. The same is true for the other party in a three-dimensional image telephone call, so that both parties can be in a two-way three-dimensional image telephone call with the best image quality. In order to ensure that each viewer is accurately facing the cameras 33 and 34, it may be desirable to ensure that the virtual observer window for each eye is not k-like for each eye, and can limit the viewer's horizon to the viewer camera. The direction is wrong in position and direction. By mounting the device toward the target of the photograph, the mount can take a three-dimensional photograph of the target. Or, you can use the small button on the domain to indicate the user's use, so as to complete the installation of the guide field, such as the financial direction setting. The device can also have an eye tracking function. Here, the general formula can be used to omnipotently display the three-dimensional image from 79 200827953 or use any other method to generate a three-dimensional image. The cameras 33 and 34 respectively record the user's right eye. And left eye images. From these images, the hybrid/you, oblique' will be used on the handheld device corresponding to the other party in the third, and the other one will be generated from the camera if the three images are automatically stereoscopically displayed. = Can be used directly in the autostereoscopic display to generate two eyes = = is holographically generated 'contains from camera 33 and as ^^^ order processing' example field by making twin holographic _ computer display, full Axis; she is in autostereoscopic display ==r gambling, and it is true that the image is generated by the rf type.

Off Select two face observer windows: 曰 1 Better distance, also provides the advantage of surpassing the autostereoscopic system. In the stereo display system, the distance between the left eye and the right image is the tendency to fix the hardware. , fixed clothing 81 200827953 G. Plane projector comprising one or two pairs of organic light-emitting body and optical address space light modulator combination or one or two electronic address space light modulator The light emitted by the system from the device can also be projected onto a screen or wall or some other surface instead of the way the projected light is directed to several virtual observer windows as described in Section F. Therefore, a three-dimensional display device that picks up a telephone or a personal digital device or in another device can also be used as a pocket type projector. Hunting can be improved by using the spatial light to change the amplitude and phase of the human light to enhance the footprint of the full-featured photo. Therefore, a complex-valued hologram can be coded on a spatial light modulator to make the reconstructed image on the screen or wall of a better quality. The combination of one or two pairs of organic light-emitting diodes described in the first part and the optical type ~=work optical machine|§ combination or one or two electronically-positioned space finers can be used as Empty county!!·In the projector towel. * The size of this portfolio is tight and the job will be tight. The projector can even be switched between = phone or personal number (four) or some (four) devices: "and", projector mode. Weiru 82 200827953 200827953 With very good image quality Compared with the conventional 2D projector, the holographic 2D projector has a non-shadow lens and the projection image is all in the optical long-range. . A conventional omni-directional 2D projector, for example in the content of w〇2〇〇5/〇柳幻,: uses a single-space optical modulator, so complex modulation cannot be performed 3 Two-dimensional projector, which will be able to perform complex modulation, so it can use H- or two-infrared organic light-emitting diode display and light-to-light modulation (4). The combination of the organic light-emitting diode display and the optically-addressed space light (for example, the shaft capacity described in Part A) can also be used in the vertical, which is in the eyes of the viewers. The autostereoscopic display is not as comfortable as a device like a device, although the body display is provided automatically compared to the full gamma + (four) 7 - secret. Automatic view area display: Only the field of view is available for several viewing areas' view view from each view. If the viewer's eyes are in a different difference 7 automatically = to the ground _. The auto-stereoscopic display and holographic technology provide two flat images, while the holographic technology provides z_information for a target point in the three-dimensional % view. 83 200827953 Typically, autostereoscopic displays are based on spatial multiplexing of the viewing area on the display and use photon spectroscopy elements such as lenticulars, barrier masks or sputum (prism) Masks). Obstacle obscuration can also be called "parallax barrier". The disadvantage of the autostereoscopic display is that the resolution of each viewing area will be inversely proportional to the reading of the light domain. However, the disadvantages can be obtained by the advantages of the autostereoscopic display as described above. To compensate. The close combination of an infrared organic light-emitting diode display and an amplitude-modulated optically-addressed spatial light modulator (such as described in Section A) can be used to make a high-resolution amplitude-modulated display. If the infrared organic light-emitting diode display device and the amplitude-modulated optical address space _Wei's close combination is combined with the beam splitter element, a high-resolution automatic vertical axis display can be constructed: tightly combined High resolution compensates for loss of resolution due to spatial multiplex. 'For autostereoscopic displays that require one or more additional optically addressed spatial light modulators, use one or more organic light-emitting diode arrays The tightness of the optical modulator with an optical address space (for example, the internal frequency J described in sections A and b has the advantage that the optical address space of the __ is optically tuned. ^ The display comprises a beam splitter and an organic light-emitting diode array, which may have processed products by a luminescent organic light-emitting diode, for example: in a beam splitter _ and 84 200827953 organic light-emitting diodes (Μ()ίΓέ峨(10). In contrast, the f-signal in the tightly combined optical address space is continuous: during the beam splitter only, periodic artifacts do not occur. Autostereoscopic display The light source can be one or more light sources, such as a light emitting diode, a laser, an organic light emitting diode or a cold cathode fluorescent lamp. The light source does not need to be homogenous. If the timing is to emit the diode and Autostereoscopic display _ shows the color image, which will require color filtering layer II, such as red, green and blue, between the light source and the light emission display!

In another embodiment, the combination of the close combination of the two pairs of organic light-emitting diode arrays and the optically-addressed spatial light modulator can be used to record the secrets of the line with her, such as B-injury. "The _ valley. Therefore, by the plural of the vibration of her domain, it can be coded in the transport light one by one.

Finally, the software that performs the calculations will only be 'received verbs' or 1: device:. This will reduce the memory requirements of the mobile phone and the range of _, and will increase the protection of any corporate secrets in the code. While most of the three-dimensional image display calculations may be performed by the intermediate system 224, it is also possible that some of the maps are performed. For example, if two flip images are turned to her, if the image planes on both sides are sent to the difference image between the first and second images, the difference image is very easy to perform and can help the poor material transfer. , _ can promote the transmission of Yang. The same can be done with a few images, such as uncompressed image data. 87 200827953 In the secret example of FIG. 22, the first image and the second image are formed - the stereoscopic image is displayed, and is transmitted by the user's device to the center of the intermediate garment 22 via the wire. The first conveyance image may be a difference image between two stereoscopic display images 'because the difference image will typically require less material than the full image.

Systems similar to those described above can also be adapted to content provided by non-TV broadcasters, such as movie or video tape providers. 200827953 In another type of pure towel, the viewer can pay for the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The 2D content provided can be, for example, an MP3 _ for a home movie, an image of a video call or a picture. The mid-level job system can include a computer to perform calculations, such that the three-dimensional image, such as a computer, produces a full-image image of an autostereoscopic image. It is best to _ in the two-dimensional content of the person 1, read the second _ like the computer between the content viewers to transfer the network to perform the calculation, because this will be more efficient than the domain-based program on the viewer side . A computer located on the transmission network can be used to perform a large number of two-dimensional to three-dimensional (four)-changing image processing at the same time. This allows for more efficient axis fine calculations, for example, by reducing the number of unused, non-using processing capabilities. If the required computing power is reduced, then the cost of the t-axis will not be reduced, because it will require less electricity "I-channel...the L-body" and the different demand will be transmitted in the network. The computer on the road is very different. Reading the software that performs the calculation will only need to be installed on the transmission network 4 'Do not need to be installed in the viewer's three device wipes. This will reduce the viewer's - axis device The scope of the savvy needs to be related to software piracy, and will: protect any corporate secrets in the private code. Although most of the three-dimensional images show that the two pulls can be performed by the towel H, but it is possible - some images The calculation is performed on the viewer's two-axis device. The three-image display device can perform some image calculations, such as decompressing the pressed image (four), or from the two-point image with its 91 200827953 corresponding depth map. The holographic coding of the spatial light modulator is generated. In the case of an example towel, (4) the secret material can be calculated by using a calculation material converted between the two-dimensional image and the three-dimensional image, and the corresponding depth map of the received thorn image is calculated. Image 'requires 2D image in three Three elements in the main color, together with their corresponding depth maps. Next, the data about the two-dimensional image and the depth map will convey the three-dimensional display device of the Lu Qian viewer. The viewer's three-dimensional display device will be in its space. In the optical modulator, 'according to the received two-dimensional image and depth map, the full-image image is encoded. In order to use the transmission bandwidth efficiently, the data transmitted in this system can be used for the conventional pressure 2' and is received. The corresponding decompression action is performed in the device. The use of the most scalable bead compression amount takes the cost of the data decompression function to the three-dimensional display device to be balanced compared to the bandwidth requirement for compressing the reduced data. Accessing 6 pairs of squashed data and attempting to find a pair of 3D data calculated by it, or it can access a known 2D graphic and attempt to find a stable 2D image in it Pairing of dragons.

For example, a three-dimensional image of a human face can be expressed 92200827953

For the information of a middle decoration P, ^ G Wei, plus facial expression changes, such as smile f, etc. plus the length of the hair, because the hair may remain after the data storage _ fruit group persistence difference occurs The record that the intermediate device has accessed: the display material is out of date', for example, over a long period of time, the length of the person's hair has been significantly modified (1) the material that has been accessed by the towel unit can be updated by the intermediate device 224. If Nakasaki does not find a good paired-dimensional image in the records it has accessed, it will add a new calculated three-form to the record. ^ K·Operator Window Spatial Multiplexing and Two-Dimensional Encoding * This embodiment is about the spatial multiplexing of virtual observer windows (vows) for holographic display devices, combined with the use of two-dimensional encoding. In addition, the hologram display device can be as described in the section A' B ' c or D, or any conventional hologram display device. A number of pseudo-view windows, such as a virtual observer window that is thinner than the left eye and a virtual observer window for the right eye, are known to be space or time multiplexed. With regard to spatial multiplexing, two virtual observer windows are generated at the same point in time and are distinguished by a beam splitter, similar to autostereoscopic display crying, as described in WO 2006/027228. As for time multiplex, ''Luzhan Station's Chabei window is produced in time. 93 200827953 However, conventional holographic display systems have some drawbacks. For space multiplex, the photo (4) used is spatially tuned in the horizontal direction, and is based on a horizontal line source and a lenticular array, as shown in Fig. 4 by the conventional technique w〇 20_28. This has the advantage of utilizing the known techniques of autostereoscopic displays. However, its disadvantage is that holographic weighting in the horizontal direction is impossible. Instead, so-called 1D coding is used, which produces holographic reconstruction and moving parallax only in the vertical direction. Thus the 'vertical focus is on the plane of the reconstructed object and the horizontal focus is on the plane of the spatial light modulator. These astigmatisms reduce the quality of spatial vision', meaning that it reduces the amount of holographic reconstruction that the viewer receives. Similarly, time multiplex systems also have the disadvantage that the paste requires a fast spatial light modulation H that is not yet available in all display sizes, and is immediately too expensive to obtain. Into, only two-dimensional code provides holographic reconstruction in both horizontal and vertical directions, so - quasi-encoding will not produce astigmatism, astigmatism will reduce the quality of spatial vision, which means reducing the viewer's holographic image quality. Accordingly, the purpose of this embodiment is to achieve spatial multiplexing of virtual observer windows in conjunction with two-dimensional encoding. In this embodiment, illumination with horizontal and vertical local spatial coherence will be combined with a beam splitter that splits the light into light for the left eye virtual observer window and for the right eye virtual observer window. Therefore, the diffraction of the beam splitter at 94 200827953 must be considered. The beam splitter can be a prism array, a second lens array (e.g., a static array or a variable array, as shown in Figure 20) or a barrier mask. An example of this embodiment is shown in Figure twenty-fifth. Figure 25 is a schematic diagram of a holographic display device including a light source of a two-dimensional light source array, a lens of a two-dimensional lens array, a spatial light modulator, and a beam splitter. The beam splitter splits the radiant light leaving the spatial light modulator into two beams, illuminating the virtual observer window (VOWL) for the left eye and the virtual observation window for the right eye (v〇wr) . In this example, the number of light sources is one or more; the number of lenses is the same as the number of light sources. y In this example, the beam splitter is behind the spatial light modulator. The positions of the beam splitter and the spatial light modulation 11 can also be exchanged. An example of this embodiment is shown in w twenty-six, in which a prism array is used as a beam splitter. Photo/Sun and Moon devices Two-dimensional light source arrays (LSI, LS2, ... LSn) containing n elements and -dimensional lens arrays (L1, L2, ... Ln) of 'n elements' are only shown in Figure 26 Two light sources and two lenses. Each light source is imaged to the observer plane using its associated lens. The source array spacing and lens spacing are such that all source images can appear simultaneously in the observer plane, i.e., the plane containing the two virtual observer windows. In Figure 26, the left-eye virtual observer window (v〇WL) and the right-eye virtual observer window (VOWR) are not shown because they are outside the figure and are on the right side of the figure. Additional field of view lenses can be added. In order to provide sufficient space for the same, the lens array's 95 200827953 spacing is similar to the sub-size of the second, that is, the silk read conversion. Illumination is horizontal and vertical in each of the translucent, is small or a point source 'and _ uses a two-dimensional lens _. The lens _ can be refractive, diffractive or holographic. In this example, the beam splitter is a dimensional vertical prism array. The light incident on the prism-bevel will be deflected to the left eye virtual observation window (tQ v〇wl), and the light incident on the other slope of the prism will be skewed to the right eye virtual observer window (t〇v) . The light from the _ LS and _ lens ray is also _ after passing through the beam splitter. For this reason, a two-dimensional code with a straight and horizontal money and a vertical and horizontal moving parallax is possible. The hologram is encoded on a spatial light modulator with two-dimensional code. The hologram for the left and right eyes is an interlacing of a block, meaning that the position will misinterpret the holographic information for the left and right eyes. More preferably, there is a stop for the left eye hologram information and a shed for the right eye hologram information under each prism. Another method, there may be two or more all-image block stops under the slope of each prism, for example two stops for the left-eye virtual observer window, and then for the right eye The virtual observer window is blocked. The spacing of the beam splitters may be the same as the spacing of the spatial light modulators, or an integer (eg two or three) multiples, or, in order to allow for perspective sh缩短rtening, the beam splitter spacing may be 96 200827953 The spacing of the spatial light modulator is slightly smaller—points, or slightly smaller than its integer (for example, two or three) multiples. Light emitted from a field with a full-eye image of the left eye reconstructs the target for the left eye and illuminates the left-eye virtual observer window (V0WL); the recorded light from the full-eye image of the right eye reconstructs the target for the right eye , and the right eye virtual observation M window (v 〇 job). • For this reason, every eye will see an appropriate reconstruction. If the pitch of the prism array is sufficiently small, the eye cannot resolve the prism structure and the prism structure does not interfere with the line of the hologram. Every - eye-catching will see a reconstruction with full focus and full shift purity, and no astigmatism. There will be diffraction on the beam splitter because the same dimming will illuminate the beam splitter. The beam splitter can be viewed as a diffraction grating that produces multiple diffraction classes. Oblique prism • The bevel has the effect of a blazed grating. For blazed gratings, the maximum intensity is the guide. The characteristic diffraction class. For a prism array, one maximum intensity will be directed from one of the prisms to the diffractive level at the virtual observer window of the left eye, and the other maximum intensity will be directed from the other slope of the prism to another winding at the virtual observer window position of the right eye. Shooting class. More precisely, the maximum intensity of the enveloping sinc>Squared function is moved to these positions, while the diffractive class is in a fixed position. The prism array produces a maximum intensity of the sinosquared function at the position of the left-eye virtual observer window, and another 97 200827953 intensity-encapsulated sinc_squared function maximum at the position of the right-eye virtual observer window. The intensity of the other diffraction classes will be small (the maximum value of the βρ sinc squared intensity function is narrow) and will not cause interference crosstalk because the fill factor of the prism array is large, for example close to 1 (8)%. As can be seen in the prior art, in order to provide a virtual observer window to two or more observers, by using a more complex prism array (for example, two types of prisms, having the same apex angle, but different non- The degree of symmetry, continuously adjacent to each other), creates a virtual observer window. However, the use of static prism arrays does not allow individual observers to be tracked. In another example, more than one light source can be used per lens. A light source outside each lens can be utilized to create additional virtual observer windows for additional observers. This is an example of a light source provided for _m observers in WO 2004/044659 (US2006/0055994). In this further example, the example towel, _ each lens m system and double laps between the hometown production is solid left ' ^ virtual observer window and m right virtual weaver window, provided to m observers. The m light sources of each lens are in a corresponding manner of (4), where the melon is an integer. This is followed by an example of this embodiment. Use a 2 inch inch screen size with the following parameter values: observer distance 2m, pixel pitch vertically for cucurbits, water 98 200827953 flat 207μηι, using Burckhardt encoding, and optical wavelength For 633^. The Burckhardt code is in the vertical direction with a sub-pixel pitch of 69 μm and a virtual observer window (vertical period) of 6 mm height. Ignoring the perspective shortening, the vertical prism array has a pitch of 414 μm, that is, a barrier with two spatial light modulations under each full prism. Therefore, the horizontal period in the observer plane is 3 mm. This is also the width of the virtual observer window. This width is smaller than the ideal pupil of the eye by about 4 mm in diameter. In another similar example, if the spatial light modulator has a smaller pitch of 50 μm, the virtual observer window will have a width of 25 mm. If the adult eye is separated by 65mm (this is typical), the prism must be deflected by 32.5mm of light, where the light will be the same as the plane containing the virtual observer window. More precisely, the maximum value of the strength package sinc_Squared function requires a skew of 32.5mm. This is equivalent to a 〇 93 for an observer distance of 2 m. Angle. For prism refractive index n = 1 · 5, the appropriate prism angle is ± 1.86. . The prism angle is defined as the angle between the base and the bevel of the prism. For the level in the 3 mm observer plane, the position of the other eye is at a distance of about 21 diffraction stages (ie, 65 faces divided by 3 mm). The crosstalk between the left-eye virtual observer window and the right-eye virtual observer window caused by the higher diffractive class of another virtual viewer window is thus negligible. 99 200827953 In order to implement tracking, the light source tracking is a simple tracking method, which means adapting the position of the light source. If the spatial light modulator is not on the same plane as the prism array, 'between the spatial light modulator pixels and the prism, there will be a disturbing related lateral offset caused by the parallax. This will probably cause disturbing crosstalk. In the above example, a pixel of 2 inches of screen size may have a fill factor of 70% in the direction perpendicular to the axis formed by the tip of each prism, that is, on each side, the pixel size is 145 μm. 31μιη inactive area. If the construction area of the prism array is directed to a spatial light modulator, the separation between the prism array and the spatial light modulator may be approximately 1 mm. The horizontal tracking range without crosstalk will be ± 2 m = ± 62 mm. If small crosstalk is tolerable, the range of tracking will be larger. This tracking range is not very large, but it is enough to allow some tracking to take place, so that the viewer will have fewer restrictions, such as limiting the placement of his/her eyes. The parallax between the spatial light modulator and the prism array can be avoided. The better way is to integrate the prism array or directly integrate it into the spatial light modulator (such as refraction, diffraction or hologram). Prism array). This will be a specialized component for the product. Another option is the lateral mechanical movement of the prism array, although this is less recommended because moving the mechanical part can complicate the device. ^ 100 200827953 Another key issue is determined by the prism angle (4) fixed virtual observer window separation. This may be confusing for non-standard eye _ observation M or tracking. One of the solutions is to make a combination of encapsulated liquid-crystal domains, as shown in Figure 丄. Next, the electric field controls the sugar, as well as the skewed seam. This method can be combined with the prism array to continuously provide variable skew and fixed skew continuously. In another Φ solution, the liquid crystal layer can be used to cover the structural edges of the prism array. Then, the electric field can control the refractive index and the skew angle. Skew combinations are not needed if the virtual observer window is sufficiently permissible to allow for a single eye to separate and observe such a large width. A more complicated solution is to use a controllable prism array, such as an e-wetting array (as shown in Figure 27) or a prism filled with liquid crystals (as shown in Figure 2). The layer having the prism element 159 includes electrodes 1517, 1518 and a cavity filled with two separated liquids 1519, 1520. Each liquid fills the concave and the same prismatic portion. As an example, the liquid can be oil or water. The slope of the interface between the liquids 1519, 1520 is determined by the voltage applied to the electrodes 1517, 1518. If the liquids have different refractive indices, the beam will be biased, and the bias is determined by the voltage applied to the electrodes 1517, 1518. Thus, prism element 159 acts as a cool, controllable beam directing element. For the implementation of the need to track the virtual observer window to the observation of the eye, the electronic hologram technology is provided, which is an important feature for the applicant's method 101 200827953. Patent application No. 07024237.0, DE 702 423 6.2 6.2, filed by the applicant, describes the singularity of the prismatic element from the virtual observation window to the eyes of the spectator.

This is an embodiment for a compact handheld display. Sdk〇 (rtm) Epson (RTM) Corporation of Japan has published a monochrome electronic address space optical tone appropriator, such as the D4:L3D13U U Yingye screen size. An example of a description is to use the D4:L3D13U LCD panel as a spatial light modulator. It has HDTV resolution (192〇 X 1〇8〇 pixels), papaya pixel pitch and 28.8 Cong X 16.2mm panel area. This panel is typically used in 2D image projection displays. This example is to calculate the observer distance for a wavelength of 663 nm and 5 〇 cm. For this amplitude modulation, Langguang's limbs are _bit-coded (Bukhart's code). Two pixels are required to encode a complex number. The three associated pixels are vertically aligned. • If the prism array beam splitter is integrated into the spatial light modulator, the prism array will have a pitch of 30 divisions. If the spacing between the spatial light modulator and the prism array has a sub-k prism array, the spacing will be slightly different to handle the perspective shortening. The height of the virtual observer window is determined by the complex spacing of 3 * 15 μπι = 45 μηη and is 7. coffee. The width of the virtual observer window is determined by the 30-inch spacing of the array and is 1 〇 6 deleted. Both mine values are greater than the eyesight = 102 200827953 Pupil. Therefore, if the virtual observer window is in the position of the eye, the hologram reconstruction can be seen in each eye. The hologram 4 is built from the full side of the two-dimensional code, so there is no such thing as the above - the dimensional code towel itself has a _light problem. This ensures high spatial visual quality and high depth impression (depthimp). When the eye is separated by Mmm, the prism must be skewed by the light. More precisely, the maximum intensity of the county sinc_squared35 degree function requires a skewed 32.5 face. For an observer distance of 〇5 m, this corresponds to soil (3). Angle. For the refractive index η-I.5, the appropriate prism ostensibility is ±7.44. . The prism angle is defined as the angle between the base and the bevel of the prism. For the level in the 10.6 mm observer plane, the position of the other eye is at a distance of about 6 diffraction stages (ie 65 mm divided by 1 〇 6 mm). The crosstalk caused by the higher diffraction order is thus negligible because the prism array has a high fill factor, meaning close to 100%. This is an embodiment for use with large displays. The holographic display unit can be designed with a phase-modulated spatial light modulator with a pixel pitch of 50jLlm and a screen size of 20 inches. For applications such as television, the screen size can be quite close to 40 inches. The observer distance for this design is 2m and the wavelength is 633nm. 103 200827953 Encodes a complex number using two phase-modulated pixels of a spatial light modulator. The two associated pixels are vertically arranged and the corresponding vertical spacing is 2 * 5 〇 = 100 μιη. By integrating the prism array into the spatial light modulator, the horizontal spacing of the prism array is also 2*50 μπι = 100 μηη, since each prism contains two bevels, and each bevel is used for a spatial light modulator. A block. The width and height of the resulting 12Jmm virtual observer window is larger than the pupil of the eye. Therefore, if the virtual spectator window is in the position of the eye, each eye can see the hologram. The reconstruction of the king image is from the two-dimensional coded hologram, so there is no one-dimensional code. In the light of Lai. This ensures high visual quality and high depth impression quality. ^ When the separation of the eyes is 65 cafés, the prisms must be deflected by the light soil. More precisely, the maximum value of the strength-encapsulated sinC-SqUared function requires skewed 5 faces.

Observer distance of object m, which corresponds to ± 〇 93. Angle. For a refractive index of ~5 ′, the appropriate prism angle is ±. The limb between the edges of the edge. The difference is (4) the base and the prism are inclined 50 cm. 上面 The above example is the distance m for the observer from the spatial light modulator. In summary, this embodiment can take a distance of between 5 and 1 . The size of the screen can be between: Between the screen and the screen (for example, the large size TV);丨, 咖列如行动电话次104 200827953 Laser source RGB solid-state laser source, for example based on indium gallium arsenide (GalnAs) or indium gallium arsenide (GalnAsN) materials, for compact holographic display devices Suitable light sources because they are compact and have a high degree of light directivity. Such light sources include RGB Vertical Cavity Surface Emitting Lasers (VCSELs) manufactured by Novalux (RTM) Inc" CA, USA. Such sources can be provided as a single laser or laser array, although each The light source can utilize a diffractive optical element to generate a plurality of light beams. The light beam can be transmitted in a multimode fiber because if the homology is too high for use in a compact holographic display device, this may reduce the homology class, and It does not lead to unwanted processed products, such as laser shift patterns. The array of laser light sources can be one-dimensional or two-dimensional. Organic light-emitting diode materials Infrared organic light-emitting diode materials have been proposed. For example, Del Cafio et al. published electroluminescence in organic light-emitting diode materials based on perylenediimide-doped tris (8-quinolinolato) aluminium, as in Applied Physics Letters voL 88, 071117 (2006). Described. Illustrates electroluminescence at a wavelength of 805 nm. Domercq et al. published near J Phys Chem B vol 108, 8647-8651 (2004) The material of the infrared organic light-emitting diode 105 200827953. The preparation of the organic light-emitting diode material on the transparent substrate is already known. For example, in US 7,098,591, the organic light-emitting diode material is in transparent indium oxide. Prepared on indium tin oxide electrodes. The electrodes are prepared on a transparent plate, and the transparent substrate can be made of borosilicate glass as 0. This is included in 83.) These components can be included in a transparent substrate. In the organic light-emitting diode device, the indium tin oxide layer can be recorded by using a radio frequency magnetron sputtering tool to

Above the substrate. Indium tin oxide can be sputtered using a target comprising indium oxide and tin oxide. The indium tin oxide layer can have an optical transmission of about 85% in the visible range. Indium tin oxide can be smooth to avoid localized electric field generation, and local enhanced electric field may reduce the effectiveness of the organic light-emitting diode material. A root mean square roughness of less than about 2] is preferred. One or several practical organic layers may be disposed on the patterned electrode surface. The thickness of the organic layer is typically between 2 nm and 200 nm. The conductive layer can be constructed on the organic layer in accordance with the pattern to form an anode and a cathode on both sides of the organic layer. The device may be sealed by a layer of glass to protect the active layer from environmental damage. Summary Manufacturing Procedures The following outlines the procedures for making the Figure 2 device, but many variations of this program will be found in the prior art. In the process of manufacturing the device of Fig. 2, a transparent substrate is selected for use. Such a substrate 106 200827953 may be a rigid substrate 'eg, about 200 μm thick shed glass sheets, or it may be a flexible substrate 'such as a p〇lymer substrate, such as polycarbonate, Acrylic, polypropylene (p〇lypr〇pyiene), polyurethane, polystyrene, polychloroprene (tetra), or similar substrates. As described in the previous section, the transparent electrode is fabricated on glass. As described in the previous section, the infrared organic light emitting diode material is disposed on the glass, and the electrical contacts are disposed on the other side of the transparent electrode, so that the pixelated organic light emitting diode infrared light is Radiation is possible. The glass substrate can have a recess that provides an organic light emitting diode pixel material. Infrared organic light-emitting diode materials can be printed, sprayed or dissolved on Muti〇n-processed) on a transparent substrate. The sub-sealing layer, which is also an electrically insulating layer, is then disposed on the organic light-emitting diode pixel layer. Such a sealing layer may be an inorganic insulating layer (such as cerium oxide layer), such as cerium oxide (silic 〇ndi〇xide), nitrite (four) ic_cut (four) icon carbide) or it may be a polymeric layer ____丨_ , such as the ring. The configuration can be performed by sputtering or by chemical vapour deposition for the inorganic insulating layer or by printing or coating* for the polymeric layer. The sub-sealing layer, which is also an electrically insulating layer, may have a thickness of a few micrometers or a thickness of m. In addition, the photosensitive layer of the optically addressed spatial light modulator covers the encapsulation layer. Sensing to ride the infrared is sensitive, the skin is transparent ^ 2 has a thickness of a few microns. Such optical properties can be accomplished by the infrared absorbing dye optically addressed spatial light modulator followed by the configuration of a liquid crystal layer overlying the two conductive layers 200827953. The liquid crystal layer can be set for amplitude modulation or phase modulation, and typically has a thickness of a few microns. Next, an infrared filter layer is placed on the device. This may be in the form of a thin layer of polymer having infra red absent pigments, or it may be an inorganic layer, such as a thin layer of cerium oxide grown by sputtering or chemical vapor deposition with red/external absorbing elements. Floor. The layer between the two optical +-addressed spatial modulator devices must be thick enough to ensure that the electric field in the scaly-addressed empty county does not affect another optically-addressed space paste. The performance of the transformer. The infrared ray is too thick enough to achieve this goal. However, if the infrared filter is not sufficiently thick, it can be combined with the optically-addressed spatial light modulator device and the eight-knife thickness handle or by configuring an additional optically transparent layer. For example, the above-mentioned money is lightly found to increase the thickness of the layer. In any case, the two optically positioned spatial tones are quite awkward, and the placement can make her too far, so that the optical diffraction effect reduces the pixel string θ. For example, if the pixel width is the job-meter, the light-to-light modulator layer should be separated from the small worker H (four). The liquid crystal layer in one of the optical addresses is set to perform the vibration-addressed spatial light modulator in the A/Ok day layer which is set to perform phase modulation. The other part of the device can be made into a single-element, and then 乂nm, using the above-mentioned other parts 108 for the light-modulation of each of the silk-addressed spaces. " , ° mouth ^ clothing on the part of the brother, the use of, for example, to ensure that the optical positioning is appropriate, the building is separated by a sufficient separation of the glass: the mother - an optical address space fine Wei electric field Will not affect another use of the solid-fixed kiss gamma t|§_.

The pixel of the photodiode layer may be precisely arranged by the pixels of the organic light-emitting diode layer, or may be thinned with a conductive transparent electrode (such as indium tin oxide). A spacer layer is used instead of a spacer layer having a sufficient thickness in close proximity to the optical neo-space light modulator. This electrode acts as the same electrode of the two liquid crystal layers. Furthermore, as a conductive electrode it is an equipotential surface (eq_ential). Therefore, it tilts the electric field, and the neon prevents the electric field leakage from being optically addressed to the optical space. Figure 9 shows an example of a device structure which can be performed by the above procedure or a similar symplectic sequence. During use, the surface illumination is sufficient to align the visible light to the smear structure of the Figure IX, so that the viewer at the point 911 can see the three-dimensional image from the device-section Lin (related to the dimensions of the device). The layers in the device, from 9〇 to _, do not need to be related to each other's dimensions. Layer 9 is a substrate layer, such as a glass layer. The layer 91 is an organic light-emitting diode bottom layer, which provides an organic light-emitting diode power supply, and 109 200827953 y is a Wang Zi 卩 卩 。. The layer % is an infrared organic light emitting diode_. Layer % is a Bragged (four) hologram element for at least part of the infrared fineness. In some embodiments the 'layer 93' can be omitted. The layer correction is an electrical insulation layer. Layer % is the optical dimming and electrode layer of the optical pre-site. The layer % is a liquid crystal layer that modulates the amplitude of the visible beam. Layer 97 is a sub-layer, and the remuneration is a thin separation layer. Layer 98 is a transparent electrode layer. Layer 99 is a linear polarizing layer. The layer_ is an infrared filter layer that transmits visible light' but blocks the liquid crystal layer from the organic light-emitting diode array % and the infrared light layer 901 for phase modulation of the visible light beam. Layer evasion is a separation layer, especially _ points _. Layer 9〇3 is an optically addressed spatial light-tuning thief light and electrode layer. Layer 904 is an electrical layer. Layer 9Q5 is a Bragg transitioner hologram element for at least partial infrared light alignment. In some embodiments, layer tearing can be omitted. Layer 906 is an array of infrared organic light emitting diodes. | 9〇7 is an organic light-emitting diode bottom layer. The light-emitting diode is a light-emitting diode and can be transparent to all or part of it. The layer is the plane of the covering material, such as glass. During the manufacturing process, the fabrication of the swells can be configured from the base, and each layer is sequentially configured until the last layer 908 is added. The above described procedure has the advantage of facilitating a highly accurate structure of the layer arrangement. Alternatively, the manufacture of the layer can be divided into two or more sections and bonded together with a sufficient degree of adjustment. For the manufacture of the device, it is important to maintain the unwanted birefringence at a minimum [e.g., unwanted stress causes birefringence 110 200827953 birefringence). Stress induced birefringence causes a linear or circularly polarized state of light to change to an elliptically polarized state of light. In devices with ideal linear or circularly polarized states of light, the presence of elliptically polarized states of light reduces contrast and color fidelity, and therefore reduces device performance. Implementation 10 Based on conventional techniques, for the optically addressed spatial light gamma of the above embodiments, a photosensitive layer that is transparent in the visible range but absorbs infrared light is required. In another implementation, the photosensitive layer can be patterned to provide transparent spacing that transmits visible light, such as red, green, and blue light beams, as well as non-transparent that is sensitive to light from organic light-emitting diodes. region. In this example, the photosensitive material need not be transparent to visible light. In addition, the write beam does not need to be infrared light. In one implementation, the write beam can be produced by a non-primary display color, for example φ by an H-color organic light-emitting diode. The filtering between the two optically addressed spatial light modulators • will therefore need to be in the yellow towel, with a strong optical absorption, so that it can block yellow light, but for the purpose of producing a functioning optical display At other optical wavelengths, it is necessary to have sufficient transmission. In another implementation, the write beam can be produced by an ultraviolet organic light emitting diode. The filter between the two optically-spaced spatially modulated enthalpy will therefore need to be in the ultraviolet light, with a strong light pre-absorption to make the rest of the UV-blocking light, but in order to achieve a productive photon, (iv) in other optics There is still a need for sufficient transmission at the wavelength. 111 200827953 Standby and external organic light-emitting diode materials have been published by Qiu et al. Applied Physics Letters 79, 2276 (2001) and Wong et al. Org· Lett 7 (23), 5131 (2005). In addition, although the use of organic light-emitting diode materials is emphasized, other light-emitting diode materials or other display technologies such as Surface-conduction Electron-emitter Display (SED) technology can be used. Although the embodiments described herein emphasize continuous encoding of amplitude and phase in a spatial light modulator, based on conventional techniques, any combination of two unequal combinations of amplitude and phase is fully encoded. Like a pixel, it doesn't matter if the two are combined with any number of shells, but not by any complex number (except for real numbers). The reason is that the vector hologram of the possible hologram of the pixel will be extended in the vector space perception by any two unequal combinations of amplitude and phase. Any two combination disks multiplied by any real number will be tied to the money. Plural (except real numbers). The relevant dimensions shown in the reference figures are not necessarily to scale.
