Abstract

The invention relates to the technical field of displaying, in particular to a holographic representation device, a holographic representation method, holographic realization equipment and a holographic realization method. The holographic representation device comprises photorefraction crystals and a light source, wherein the photorefraction crystals respectively record holographic images at multiple different angles, the light source provides lots of representation light incident on the photorefraction crystals from the different angles, and the representation light is the same as reference light in frequency and optical distance when the holographic images are formed. According to the holographic representation device, the representation lights incident on the photorefraction crystals from the different angles are utilized to be irradiated to the photorefraction crystals. Because the holographic images are recorded by the photorefraction crystals at the different angles, each holographic image can be showed at different angles in a non-interfering mode, observers located on multiple positions can observe the holographic images recorded in the photorefraction crystals, and the problem that an observation angle is single in the holographic representation process is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a holographic reproduction device, a holographic reproduction method, a holographic realization device and a holographic realization method. Background technique [0002] In linear optical materials, such as lenses, prisms, etc., light beams only pass through the optical material without changing certain properties of the optical material itself. The photorefractive effect is the abbreviation of the effect of photoinduced refractive index change. It does not refer to all light-induced refractive index changes, but specifically refers to the formation of a charge field by the photoconductive effect of optical materials under light radiation, and then caused by the photoelectric effect. The effect of the variation of the refractive index with the spatial distribution of light intensity. Since the optical properties of photorefractive crystals can be changed by light passi...
