Key Specification

 
Product features: 3 dgrating
Exquisite picture color is clear,level. Each element in the picture, such as: animals, figures,flowers and plants, etc., have very strong stereo feeling anddepth, lifelike, seems to be real is just around the corner,stretched out his hand, a strong visual impact.
Technicalprinciple:
In observing objects, people cannaturally have stereo feeling, this is because people with twoeyes, have a certain distance between two eyes, and objects to forma certain Angle between left and right eyes can see the object willgenerate parallax, the parallax images, which is reflected in thebrain, the distances of space is produced and stereo feeling.Stereograms like according to the principle of the optical, makethe light refraction by a grating plate, so that the image picturewith depth.
1.The grating using optics refraction principle on the transparencyfilm extrusion line after line of parallel lines, calledgrating.

2.Three-dimensional grating materialreferred to as "grating, which is based on human visual differenceand optics refraction principle manufacturing an optical imagingmaterials, the grating fold through special processing of gratingon the drawing, you can generate a holographic image of the stereoimages, give a person with a good vision.
