1, material classification: lenticular (plates, membranes, sheets) and slit grating

2, lenticular structure: radian and media composition;

A, lenticular sheet membrane curvature is mainly produced out of the lenticular sheet, the lenticular plate sheet was produced together with the media and radian out;

B, the difference between the sheet and plate: thickness of the points, can bend;

C, membrane called the roll bending, sheet bending deformation is called;

3,Slit lenticular sheet structure: According to black and white (black and white little more than) a regular arrangement of the lenticular sheet, mainly based on the principle of diffraction of light;

The diffraction: Suppose a point source, by adjusting the hole diameter, onto the screen. Can be observed, with the hole of the narrow, circular bright on the screen also will be reduced, when the small diameter holes with a wavelength (400 to 7700 Å) can be compared, the screen will get some light and dark ring These rings far beyond the scope of the share according to the rectilinear propagation of light illuminated the area. This phenomenon is called the light diffraction light diffraction. If the hole into a small screen, narrow and filaments, etc. will also observe the phenomenon of diffraction of light (light and dark rings or light and dark stripes). These are the conditions under monochromatic illumination. If the light source is a composite light (Daylight), will observe the color ring or color stripes. Photographic lenses and other optical instruments resolving power is determined by the nature of the diffraction of light; holographic reproduction also depend on the diffraction of light to achieve.

4 cylinder slit lenticular sheet characteristics and production methods:
Slit  lenticular sheet:
Features:
High-resolution, 3d lenticular sense of strong, superior lenticular; drawback is playing lights must therefore energy consumption, narrow range of applications, mainly used in railway station interior and basement;

Production methods:
(1) Copy: Major equipment replicator, washing machine and parent material lenticular sheet; production out of the lenticular sheet is best;
(2) laser phototypesetting: mainly the use of computers and laser printers, since there is an error in resolution, so the production of inferior quality copies out of the lenticular sheet
(3) Printing: printing process due to the presence of dot phenomenon, so the quality of the produced sub-lenticular sheet, but also the most expensive raster;
Lenticular lens:

Features:
① membranes: 3d lenticular sense of strong, high clarity, transparency, and focus accurately, media flexibility, easy to transport, easy to cut, low cost, scrap rate at the end; Disadvantages: mapping complex process;
② plate: 3d lenticular sense of strong, high clarity, transparency, and focus accurately process is simple, easy to operate; Disadvantages: high cost, high rejection rate, transportation inconvenience, easily deformed and difficult to cut;
③ sheet: 3d lenticular sense of strong, high clarity, transparency, focusing accuracy, wide range of applications;
Production methods:
Membrane: a continuous roll style;
Plate: plate pressure and injection type;
Sheet: mainly used plate pressure;
