The record of 3-D image and the technology of reproduction, the first step are to record object light-wave information using principle of interference, this shot
Journey: subject forms the object beam of diffusion formula under laser irradiation；Another part laser is mapped to holographic bottom as reference beam
On piece and object beam superposition generate interference, the position phase and amplitude of each point on object light wave are converted into being spatially varying strong
Degree records interference fringe to record all information of object light wave with interval using the contrast between interference fringe
Egative film after the processing routines such as developing, being fixed, become as a hologram or hologram；Its second step is to utilize
Diffraction principle reconstructed object light-wave information, this is imaging procedures: hologram is like a complicated grating, in coherent laser illumination
Under, the diffraction light wave of the sinusoidal pattern hologram of a linear recording can generally provide two as that is, original as (also known as primary image)
And conjugate image, the image three-dimensional sense of reproduction is strong, has true visual effect, and each section of hologram all has recorded on object
The optical information of each point, therefore its each section can reproduce the whole image of the original in principle, can also be by multiple exposure
Multiple and different images is recorded on same egative film, and can be shown respectively without interfering with each other.
Holography shows currently used scheme generally using holographic glass as light propagation medium, due to needing glass, glass
Glass opens virtual image and user isolation, causes user that can not touch, can not pass through the image virtually shown, reduces technology
Mystique.Secondly, need the holographic current use scope of glass proposals too wide, user is for using the mode of holographic glass display
Freshness reduces.
