A kind of holographic technique of this drawback of big data quantity.The general principle of synthetic hologram stereogram Method of printing is that utilization space light is adjusted
Device processed, load and project several multi-perspective pictures, respectively with reference to the interference of light, interference fringe exposure to be recorded in the holography of piecemeal
On medium, several holographic cells (Hogel) are formed, during the reconstruction of hologram, when the eyes of people are in appropriate location, it will observation
To different multi-perspective pictures, so as to produce stereo perception.Static holographic stereogram is at first by the Massachusetts Institute of Technology (MIT) in the U.S.
Succeed in developing, be widely used to the fields such as military affairs, business, medical treatment at present.
At present, scholars propose more synthetic hologram stereogram print output system (CN105223795A,
Keehoon Hong et al., Resolution enhancement of holographic printer using a
Hogel overlapping method, Opt.Express21,14047-14055 (2013)；X.W.Rong et al.,

After pixel corresponding to each holographic cell between A ', B ', C ', D ' is intercepted and spliced, point of observation (x is obtained0, y0, z0) place
Synthesis multi-perspective picture；
4th step is the exposure printing of holographic stereogram；
Build holographic stereoscopic exposure map printing light path, the distance of spatial light modulator and holographic recording medium is equal to L2, displacement platform
Moving step length be equal to l2, synthesize after multi-perspective picture answers flip horizontal and reload to spatial light modulator.
2. a kind of multi-perspective picture segmentation restructuring Method of printing of synthetic hologram stereogram as claimed in claim 1, its feature exist
In spatial light modulator both can be LCDs or digital micromirror elements, can also be liquid crystal on silicon.
3. a kind of multi-perspective picture segmentation restructuring Method of printing of synthetic hologram stereogram as claimed in claim 1, its feature exist
In multi-perspective picture both can be multi-perspective picture or the utilization for shooting to obtain using camera to actual 3 D stereo object
The multi-perspective picture that computer is rendered to obtain to virtual three-dimensional model.
