Embodiment

See also Fig. 2, be depicted as full figure recording medium synoptic diagram of the present invention, desire in full figure recording medium 900, to store full figure interferogram 800, so full figure recording medium 900 (holographic storage media) comprises first substrate 910 and second substrate 930, and between first substrate 910 and second substrate 930 folder one deck recording layer 920, but this recording layer 920 is the recording light signal just, as full figure interferogram 800 etc., yet desire produces full figure interferogram 800 and must be produced by an optical system, and several optical systems that produce full figure interferogram 800 below are described.

See also Figure 1A; be depicted as first embodiment of the present invention combination synoptic diagram; the full figure store regenerated system of a kind of tool servo function of the present invention; this embodiment is applied to the full figure recording medium 900 as Fig. 2; in second substrate 930 of this full figure recording medium 900; include base material 931; protective seam 970 and servo track layer 960; protective seam 970 is positioned at the side of the not linkage record layer 920 of second substrate 930; this servo track layer 960 includes servo track 961; wavelength selective membrane 962 and wall 963; servo track 961 is formed by a plurality of potholes or projection; or utilize servo track as other existing C D/DVD disc; and servo track 961; the configuration of wavelength selective membrane 962 and wall 963; and different, its structure is in each embodiment distinctly explanation again according to the position of servo track 961.When this servo track 961 makes this servo track 961 of light beam incident, be subjected to the modulation of servo track 961 and after being reflected by this wavelength selective membrane 962, can know that just light beam is positioned at a certain position of full figure recording medium 900 after accepting by control device 700.

Light source 100 can send coherent light (coherence light), this coherent light is by behind first light guide section 200, be divided into reference light 110 and flashlight 130, and this first light guide section 200 these reference lighies 110 of guiding are incident full figure recording medium 900 along first incident direction and directly, this first incident direction is the direction of vertical incidence full figure recording medium 900 in this embodiment, and flashlight 130 by 200 beam split of first light guide section after incident one smooth space modulator (spatial light modulator, SLM) 500, after making that this flashlight 130 is subjected to these light space modulator 500 modulations, flashlight 130 by the guiding of second light guide section 300 along the second incident direction incident full figure recording medium 900, therefore flashlight 130 is identical with the polarization state of reference light 110 time, so when reference light 110 and flashlight 130 interfere with each other in the recording layer 920 of full figure recording medium 900, and produce full figure interferogram 800, and store this full figure interferogram 800 by the recording layer 920 of full figure recording medium 900.

See also Figure 1B, be depicted as the regeneration synoptic diagram of the first embodiment of the present invention, when reference light 110 during once more along first direction incident full figure interferogram 800, reference light 110 just can produce a reproduced light 150, this reproduced light 150 just can be along flashlight 130 paths and incident one two-dimensional space image sensor 350, understood this reproduced light 150 again, and this time space modulator (spatial light modulator, SLM) 500 change comprehensive blocking light condition into, and the light of light space modulator 500 enters second light guide section 300 to avoid since then.

Utilize servo light source 400 to produce servo light 410 in addition, this servo light 410 is the servo track 961 of incident full figure recording medium 900 by servo light guide section 420, and by the servo light 410 of servo track 961 modulations and reflect servo light 410, and receive by servo light sensing part 630, and be converted to electric signal and export to control device 700 to analyze and to control the whole optics framework of full figure recording medium 900 tops, make the servo light of incident focus on the servo track of full figure recording medium and follow servo track to carry out continuous moving, decipher out simultaneously the data such as address on the servo track, except that this, utilize a servo light guide section 420 again, make reference light 110 penetrate full figure recording medium 900 and by reference light catoptron 260 reflection back and be directed to reference light detecting part 610, so that reference light 110 is transferred to electric signal and transfers to control device 700, make control device 700 can analyze and adjust the relative distance and the angle of inclination of reference light catoptron 260 and reference light 110, to keep reference light catoptron 260 perpendicular to the optical axis of reference light 110 and be positioned on the focus of reference light 110, reference light 110 is kept along the first incident direction incident full figure recording medium 900, and also can make full figure interferogram 800 be recorded in the recording layer 920 of full figure recording medium 900 continuously along servo track 961.

Wherein first light guide section, 200 usefulness are so that the light that light source 100 is produced is divided into flashlight 130 and reference light 110, and guiding reference light 110 is along first direction incident full figure recording medium 900, so before utilizing polarizing board 210 to place light source 100, the light of light source 100 generations is got the light of the specific polar biased of one earlier, it is linearly polarized light, and we are adjusted into the specific polar biased direction of parallel paper to it this linearly polarized light, we are called the P polarization, if polarization state is the specific polar biased direction of vertical paper, we are called the S polarization, so after the light of light source 100 passes through polarizing board 210, just be a linearly polarized light and for the P polarization state, this linearly polarized light becomes twice light again and is respectively flashlight 130 and reference light 110 through spectroscope 220, and is all the P polarization.

And second light guide section 300 will be through flashlight 130 guiding of light space modulator 500 with along second incident direction and incident full figure recording medium 900, so can utilize lens and reflector group 310, make flashlight 130 scioptics and reflector group 310 to change flashlight 130 directions of propagation, and along second incident direction and incident full figure recording medium 900, and between lens and reflector group 310, install a pin hole 320 (pin hole), can be in order to the outer veiling glare of filtered signal light 130 with reproduced light 150, therefore, reference light 110 and flashlight 130 guiding by first light guide section 200 and second light guide section 300 following, respectively along first incident direction and second incident direction and all be incident in the recording layer 920 of full figure recording medium 900, and first light guide section 200 makes reference light 110 consistent with the polarization state of flashlight 130 with second light guide section 300, so reference light 110 is interfered mutually with flashlight 130 and is produced full figure interferogram 800, and stored by recording layer 920.

In addition, also setting up object lens 231 these object lens 231 in first light guide section 200 can make reference light 110 present converging beam and incident full figure recording medium 900.

When making reproduced state, the travel path that makes reference light 110 during with record the travel path of reference light 110 opposite, when the reference light 110 in the time of so can making regeneration passes through the full figure interferogram 800 of recording layer 920, produce conjugation reproduced light 150, this conjugation reproduced light 150 is along the path of original signal light 130 and propagate, be the reproduced light 150 of obtaining this conjugation, we utilize the beam split by polar biased spectroscope 340 of different polarization states, with the reproduced light 150 of obtaining this conjugation, therefore, in first light guide section 200, increase by first phase delay chip 250 again, reference light catoptron 260 and the 4th phase delay layer 270, and in second light guide section 300, increase by second phase delay chip 330, this first phase delay chip 250 and second phase delay chip 330, can make the P polarized light become the S polarized light, on the contrary, if when this first phase delay chip 250 of S polarized light incident or second phase delay chip 330, also can change into the P polarized light, as 1/2nd ripple plates (1/2 λ waveplate), this first phase delay chip 250 places a side of spectroscope 220, when making reference light 110 incidents first phase delay chip 250, and make reference light 110 change polarization state is the S polarization, and this 4th phase delay layer 270 is connected in a side of reference light catoptron 260, this the 4th phase delay layer 270 can make P polarized light incident the 4th phase delay layer 270 twice back and become the S polarized light, as quarter-wave plate (1/4 λ wave plate).

And second phase delay chip 330 of second light guide section 300 places flashlight 130 paths, and the first polar biased spectroscope 340 also places flashlight 130 paths, and behind flashlight 130 incident light space modulators 500, flashlight 130 is this second phase delay chip 330 of incident again, the polarization state that so just can change flashlight 130 is the S polarization, so when reference light 110 its polarization states of incident first phase delay chip 250 also are the S polarization, and flashlight 130 also changes polarization state by second phase delay chip 330 is the S polarization, so interfere and generation full figure interferogram 800 when flashlight 130 and reference light 110 mutual intersections just can produce, and stored at the recording layer 920 of full figure recording medium 900.

So during desire regeneration, it is the S polarization through the reference light 110 of first phase delay chip 250, and make reference light 110 present converging beam through object lens 231 and penetrate in the full figure recording medium 900 and when focusing on the reference light catoptron 260, make reference light 110 reference light catoptron 260 and reflecting thus along original route, and when being reflected when reference light 110 incident reference light catoptrons 260, just by two order, four phase delay layer 270, so can change the polarization state of reference light 110 is the P polarization, and during again by full figure interferogram 800, just can produce conjugation reproduced light 150, and this conjugation reproduced light 150 returns along the original route of flashlight 130, because this conjugation reproduced light 150 is incident full figure interferogram 800 and producing by the reference light 110 of P polarization, so the polarization state of this conjugation reproduced light 150 also is the P polarization, therefore, when this conjugation reproduced light 150 when the original route of flashlight 130 returns, just can pass through second phase delay chip 330, and make conjugation reproduced light 150 change polarization state is the S polarization, and during this conjugation reproduced light 150 incidents first polar biased spectroscope 340, because the polarization state of conjugation reproduced light 150 is the S polarization, so can be reflected by the first polar biased spectroscope 340, and it is other and put a two-dimensional space image sensor 350 for the reflection direction of conjugation reproduced light 150 in the first polar biased spectroscope, 340 1 sides, to accept this conjugation reproduced light 150, and understand this conjugation reproduced light 150, as Figure 1B.

In addition, have servocontrol for making system, utilize servo light source 400 to realize that with servo light guide section 420 this servo light source 400 can produce servo light 410 in addition, the wavelength of this servo light 410 is different from the wavelength of flashlight 130 and reference light 110.And servo light guide section 420 turns to servo light 410 and by object lens 231 incident full figure recording medium 900 and focusing on the servo track 961 of full figure recording medium 900; this servo track 961 is between protective seam 970 and base material 931; so this base material 931 just has interval action; so do not need wall 963; and because of servo track 961 directly in forming on the base material 931; so under this structure; wavelength selective membrane 962 just is plated on the side of servo track 961 towards protective seam 970; so servo light 410 is reflected by the wavelength selective membrane 962 of servo track 961 places coating; this servo light 410 that is reflected is the servo optical sensor 630 of incident detecting part 600 by servo light reflection mirror group 430 again; so that servo light 410 is transferred to electric signal and transfers to control device 700; make full figure interferogram 800 be recorded in full figure recording medium 900 along servo track 961 continuously by control device 700; in addition; owing to penetrating full figure recording medium 900, reference light 110 is reflected after the mirror reflection; reference light 110 is returned and incident spectroscope 220 along original route; and reference light partly 110 can be turned to by the opposite side of spectroscope 220 by these spectroscope 220 reflections; so the reference light sensor 610 of detecting part 600 is put in herein; to receive this reference light 110; and transfer this reference light 110 to electric signal; make control device 700 can analyze and adjust the relative distance and the angle of inclination of reference light catoptron 260 and reference light 110, to keep reference light catoptron 260 perpendicular to the optical axis of reference light 110 and be positioned on the focus of reference light 110.

Other first light guide section 200 also is provided with one second object lens 232, these second object lens 232 dwindle and incident object lens 231 beam diameter of reference light 110, these second object lens 232 comprise first lens 233 and second lens 234, the focus of the focus of second lens 234 and first lens 233 coincides, and the focal length of second lens 234 is less than the focal length of first lens 233, so the beam diameter of incident reference light 110 is dwindled, so just can make the size decreases of object lens 231.

The light space modulator 500 of present embodiment is a penetration light space modulator 500, as penetration liquid crystal panel etc.

The servo track of the servo track layer of full figure recording medium is set as the structure of multilayer when us, as Fig. 2, then when the servo track 961 of servo light 410 incident different layers, just make full figure interferogram 900 be stored in the recording layer 920 with having level, so just can be in order to increase the storage area of full figure recording medium 900.

See also Figure 10 and Figure 11, be depicted as ninth embodiment of the present invention combination synoptic diagram and flashlight and reference light and interfere synoptic diagram, the framework of present embodiment is also similar to first embodiment, but the spectroscope 220 of first light guide section 200 is replaced by the 3rd polar biased spectroscope 280, and the focus of its second object lens 232 overlaps with the focus of object lens 231, so, the beam diameter of reference light 110 is dwindled and in the parallel beam incident full figure recording medium 900, and interfere mutually with flashlight 130 and produce full figure interferogram 800.

Because reference light 110 bundles are the directional light pencil, so that full figure interferogram 800 can become multi-level being formed in the full figure recording medium 900, the servo track 961 of full figure recording medium also is multi-level mode if arranging in pairs or groups, just can realize except full figure interferogram 800 can only on a surface level, form, many again can on different surface levels, form full figure interferogram 800, can further improve storage volume.

See also Figure 12 A, be depicted as tenth embodiment of the present invention combination synoptic diagram, its light source 100 can send coherent light, this coherent light is by behind first light guide section 200, be divided into reference light 110 and flashlight 130, and this first light guide section 200 these flashlights 130 of guiding are incident full figure recording medium 900 along first incident direction and directly, this first incident direction is the direction of vertical incidence full figure recording medium 900 in this embodiment, before flashlight 130 incident full figure recording mediums 900, elder generation's incident light space modulator 500, after making that this flashlight 130 is subjected to 500 modulations of this light space modulator, reenter and penetrate full figure recording medium 900, and reference light 110 by the guiding of second light guide section 300 along the second incident direction incident full figure recording medium 900, when reference light 110 can be met in the recording layer 920 of full figure recording medium 900 with flashlight 130, just interfere with each other, and produce full figure interferogram 800, and store this full figure interferogram 800 by the recording layer 920 of full figure recording medium 900.

See also Figure 12 B, be depicted as tenth embodiment of the present invention regeneration synoptic diagram, so when reference light 110 during once more along second direction incident full figure interferogram 800, reference light 110 just can produce a reproduced light 150, this reproduced light 150 just penetrates this full figure recording medium 900, and incident two-dimensional space image sensor 350 is understood this reproduced light 150 again.

Utilize servo light source 400 to produce servo light 410 again, this servo light 410 is the servo track 961 of incident full figure recording medium 900 by servo light guide section 420, and by the servo light 410 of servo track 961 modulations and reflect servo light 410, and receive by detecting part 600, so can make full figure interferogram 800 be recorded in the recording layer 920 of full figure recording medium 900 continuously along servo track 961.

And an objective lens 230 is set on flashlight 130 paths, when making flashlight 130 these objective lens 230 of incident, present a parallel beam and incident full figure recording medium 900, therefore, this mode can make full figure interferogram 800 be formed in the full figure recording medium 900 with having level, be that full figure interferogram 800 can be formed on the different plane of full figure recording medium 900, and can be not that converging light reduces the interference area because of light beam, therefore when adjusting the relative position of full figure recording medium 900 and flashlight 130 and the interference position of reference light 110, full figure interferogram 800 can be formed on the different plane of full figure recording medium 900, so, can strengthen the capacity of full figure recording medium 900.

Similarly, for making this stratose full figure interferogram 800 have servomechanism, in corresponding servo track 961, also be formed with stratose servo track 961, make the stratose according to this servo track 961 of full figure interferogram 800 and continuously and can on the different-thickness position, be formed in the full figure recording medium 900.

Therefore, this first light guide section 200 includes spectroscope 220, make the light incident spectroscope 220 of light source 100 and be further divided into flashlight 130 and reference light 110, and this flashlight 130 is incident to full figure recording medium 900 along first incident direction, first incident direction of this embodiment is the direction of vertical full figure recording medium 900, and second light guide section 300 comprises above lens and an above reflector group, guiding reference light 110 changes the direction of propagation, with along second incident direction and incident full figure recording medium 900, second incident direction of this embodiment is this full figure recording medium 900 of oblique incidence.

Yet because of flashlight 130 directly penetrates directly incident full figure recording mediums 900 of light space modulator 500 back, so what be suitable for this light space modulator 500 is penetration light space modulator 500, as liquid crystal panel.

In addition, because of making flashlight 130, objective lens 230 becomes parallel beam, so realize by the object lens 231 and second object lens 232, the focus of these object lens 231 overlaps with the focus of second object lens 232, so, after flashlight 130 passes through light space modulator 500, then incident is by the objective lens 230 of object lens 231 with 230 one-tenth of second objective lens, and become a parallel beam, and servo light 410 turns to by these object lens 231 and presents converging beam and the servo track 961 of incident full figure recording medium 900.

Because of servo light 410 and flashlight 130 are shared these object lens 231, and use the middle section of object lens 231 because of flashlight 130, and servo light 410 uses the peripheral region of object lens 231, for the volume that makes object lens 231 unlikely excessive, we can make second object lens 232 have the effect that light beam dwindles, so these second object lens 232 are made up of so that incident beam dwindles a plurality of lens, and the combination with first lens 233 and second lens 234 realizes among this embodiment, the focus of the focus of these first lens 233 and second lens 234 coincides, and the focal length of second lens 234 is less than the focal length of first lens 233, and the beam diameter of the reference light 110 that spectroscope 220 produced is dwindled.
