Description
Technical field
Holographic display screen is the utility model is related to, belongs to holographic display screen technical field.
Background technology
Holographic technique is record and the reproduction using interference and diffraction principle record and the real 3-D view of reconstructed object
Technology.The first step is to utilize principle of interference record object light-wave information, this i.e. shooting process：Subject is irradiated in laser
The lower object beam for forming diffusion formula；Another part laser is used as and is mapped to reference to light beam on holofilm, and object beam superposition produces
The position phase and amplitude of each point on object light wave, are converted into the intensity being spatially varying, so that using between interference fringe by interference
Contrast and interval the full detail of object light wave is recorded.The egative film of interference fringe is record by development, fixing etc.
After processing routine, 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 just as a complicated grating, and under coherent laser illumination, a linear recording is just
The diffraction light wave of chordwise hologram can generally provide two as that is, original as being also known as primary image and conjugate image.The image of reproduction is stood
Body-sensing is strong, has real visual effect.The each section of hologram all have recorded the optical information of each point on object, therefore in principle
Its each section can reproduce the whole image of the original, by multiexposure, multiple exposure can also be recorded on same egative film it is multiple not
Same image, and can show respectively without interfering with each other.
The holographic display screen of the prior art does not have radical occlusion device, when holographic display screen for a long time when not used, will can not show
Screen protects.In order to solve above-mentioned difficulties, it is necessary to develop a holographic display screen with radical occlusion device.
The content of the invention
The purpose of this utility model is to provide holographic display screen.
Problem to be solved in the utility model is that the holographic display screen of the prior art does not have the problem of radical occlusion device.
To realize the purpose of this utility model, the technical solution adopted in the utility model is：
Holographic display screen, including holographic display screen, smooth plate, contiguous block, reflecting surface, limited block, slide, cover, screw,
Sliding block and saddle, four reflectings surface are installed on the saddle, and reflecting surface is made of the glass for being pasted with holographic film, four reflectings surface
Trapezoid body structure is formed, contiguous block is installed in trapezoid body structure, holographic projecting screen is installed on contiguous block, outside holographic projecting screen
Week installation smooth plate, saddle each side install slide, and slide upper and lower ends respectively install limited block, sliding block is installed on slide,
Sliding block is equipped with screw, and sliding block is fixed on slide by screw, and cover madial wall is installed on two sliding blocks, and cover covers on saddle
Outside.
Multiple suckers are each side installed, sucker is located at below smooth plate on the cover.
The utility model has the advantages that：Unscrew screw, move up cover, cover is covered on outside reflecting surface, make sucker to
On move close to smooth plate bottom, sucker suction tightens screw, cover is fixed on outside reflecting surface, when complete in smooth plate bottom
Cease display screen for a long time when not used, it is possible to protect display screen.
