Description
Technical field
The present invention relates to a kind of formation of hologram and 3 D stereo technique for displaying, particularly a kind of calculation holographic production and output system.
Technical background
It is one of laser holography important use field that holographic 3 D shows.General holography is to utilize the steric information of the coherence record three-dimensional body of laser, forms hologram, and utilizes diffraction principle to carry out 3 D stereo reconstruct.Along with developing rapidly of computer technology and peripherals thereof, the holography that combines with computer system constantly occurs.The synthetic hologram display system of Sony company development is the holographic production technology of representative optical, mechanical and electronic integration, and the practicability of utilizing the computer simulation two-phonon process to make hologram is in the exploratory stage, owing to there being following two big reasons: the one,, the three-dimensional body that computed hologram shows generally all is to be come out by the simulation of computing machine, is difficult to obtain the steric information of actual three-dimensional body; The 2nd,, the output of computed hologram generally all goes on foot technical notes to medium by printing and micro two, because the hologram information amount is very big, such way of output is difficult to obtain practical hologram.So the computing mechanism holographic technique does not reach practicality up till now as yet aspect 3-D display.
The research in wrappage, high-tech product false proof (American I ntel has adopted digital laser pixel holographic technique as the anti-counterfeit package of supporting on CPU) of numerical control holography is very active, and states such as the U.S., Britain, Italy have all carried out the research of numerical control holography.To introduce digitized hologram output device both at home and abroad and be called holographic printer (HoloPrinter).In the world, the manufacturing technology of digital laser holographic technique, digital diffraction optical element and the research of equipment are quite active, and the three-dimensional laser holographic printer is the key areas of the technological innovation in the following several years.At present, the hologram type system mainly contains following two types both at home and abroad:
The one, the laser hologram photo-composing system.Domestic typical equipment is the information optics Graduate School of Engineering development HoloMakerII of University Of Suzhou.The hologram of the holographic output system output of this class is called dot matrix hologram (Dot-Matrix Hologram), and this is commercial both at home and abroad at present hologram printing equipment.But though the hologram of this class device output can show 3-D view, generally all is the modeling 3-D view, rather than the reproduction of true three-dimension object picture.
The 2nd, the equipment of producing with company of Sony (sony) is the integral hologram manufacturing system of representative, its principle is to utilize the two dimensional image of digital camera photographed different visual angles and import the LCD LCDs to show, the image that shows is interfered to record plane and reference light by the post lens imaging successively, thereby forms integral hologram.But this system is the laser hologram camera system in fact still, and is high to shockproof requirement, and simultaneously because be stereoscopic synthetic hologram, the space image of reconstruct has jump and distortion.The price comparison costliness of system in addition.
Summary of the invention
The reproduction that to the objective of the invention is at the existing hologram of exporting of existing domestic and international hologram type system be not true three-dimension object picture; High to shockproof requirement, the space image of reconstruct has jump and distortion, and the weak point that the cost of system is high provides a kind of hologram of exporting can carry out the holographic demonstration of true three-dimension object; Need not carry out shockproof, that system cost the is low calculation holographic production and the output system that are used for formation of hologram and 3 D stereo demonstration.
The technical solution used in the present invention is finished in the following way: a kind of calculation holographic production and output system comprise:
Be the solid of obtaining objective to be shown and the spatial digitizer of color distribution information;
For hologram being calculated and the computing machine that formation of hologram, output are controlled;
Be LCD to the output of hologram framing;
For hologram being carried out the micropatterning system of micropatterning;
For hologram being carried out the pen recorder of substep record.
Wherein, form hologram microrecord system by LCD, micropatterning system and pen recorder.
Adopt calculation holographic production of the present invention and output system to carry out the step of formation of hologram and holographic microrecord:
Obtain the solid and the color distribution information of objective to be shown by spatial digitizer; Be converted to the three-dimensional data that calculation holographic is used after by computing machine spatial digitizer being obtained the solid of objective to be shown and color distribution information via data processing; By the computer manufacture hologram, wherein, method with the computer manufacture hologram is: simulate the wavefront of three-dimensional body thing light wave to be shown by obtaining three-dimensional data, and carry out addition before the reference light wave that makes it and simulate, thereby reach the interference effect of laser hologram, and formation holographic interference fringes image, according to the type difference of making hologram, can simulate different thing light wave wavefront, for example fresnel holography, rainbow holography, panorama holography etc.; Computed hologram is shown by transmission-type LCD, wherein, significantly computed hologram is divided into the small size hologram of some width of cloth, the pixel size of each small size hologram is consistent with the LCD pixel size, the small size hologram of some width of cloth is imported LCD in order successively and is shown, the illumination light of demonstration adopts spatial incoherent light; By the micropatterning system hologram that LCD shows is carried out the micro imaging, wherein, minification depends on the resolution of LCD, minification to guarantee last hologram resolution reach 500 lines right/millimeter; To be recorded on the high-resolution hologram recording material through the hologram of micro imaging by pen recorder, high-resolution hologram recording material can adopt high-resolution sensitive film, wherein pen recorder comprises numerical control record image planes platform and focusing supervisory system, numerical control record image planes platform can adopt two-dimentional numerical control record image planes platform, the image interlock that the mobile and LCD of two dimension numerical control record image planes platform shows, it is the every output piece image of LCD, two dimension numerical control record image planes platform just moves a position, interlock is by image output and the time shutter coupling of computer control and LCD, and last hologram is spliced by the small size hologram of some width of cloth.
The present invention compares with existing hologram type system, has following characteristics:
1, the formation of hologram is not the interference generation by laser, but is obtained by COMPUTER CALCULATION fully, with regard to having avoided the problem of vibrations, need not take earthquake counter measure like this.
2, can realize the 3D hologram demonstration of real object.
3, in the formation of hologram, pixel holographic is the pointwise recorded information, synthetic hologram is to write down stereoscopic plan view information by the width of cloth, and the present invention is partial holography figure by width of cloth record, thereby is keeping the intrinsic characteristic of hologram: partial holography figure still can show the integral body of object.
