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 the purpose of this utility model is or not true three-dimension object picture at the existing hologram of exporting of existing domestic and international hologram type system; 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 the digital hologram that is used for formation of hologram and 3 D stereo demonstration shockproof, that cost is low makes and output unit.
The technical solution adopted in the utility model is finished in the following way: a kind of digital hologram is made with output unit and is comprised spatial digitizer, computing machine and hologram microrecord system, wherein, hologram microrecord system is made up of light source, shutter, beam expanding lens, vibration frosted glass, LCD, micropatterning system, pen recorder; Be connected by the computer control line between computing machine and shutter, LCD and the pen recorder; The micropatterning system is made of miniature camera lens, and pen recorder is made of two-dimentional numerical control record image planes platform and focusing supervisory system, and beam expanding lens adopts the beam-expanding collimation lens, and vibration frosted glass is to be contained on the relevant annihilator of vibration by frosted glass to form.
In making of the utility model digital hologram and output unit, spatial digitizer is used to obtain the solid and the color distribution information of objective to be shown; Computing machine is used for hologram is calculated, and formation of hologram, output are controlled; LCD is used for the hologram framing is exported; The micropatterning system is used for hologram is carried out micropatterning; Pen recorder is used for hologram is carried out the substep record.
The utility model is compared with existing hologram type system, has following characteristics:
1, the formation of hologram is to be obtained by COMPUTER CALCULATION, has avoided the problem of vibrations, need not take earthquake counter measure.
2, can realize the 3D hologram demonstration of real object.
3, in the formation of hologram, pixel holographic is the pointwise recorded information, and synthetic hologram is to write down stereoscopic plan view information by the width of cloth, and the utility model is partial holography figure by width of cloth record, thereby keeping the intrinsic characteristic of hologram, partial holography figure still can show the integral body of object.
