Abstract

The utility model relates to a metal wire slit grating for developing stereo pictures, which can be used for the developing of the stereo pictures of the advertisement, the ornament, the printed products, and the stereophotography products. The utility model comprises the grating basal body of the transparent and colorless float glass (1), and the grating is composed of a metallic chromium layer (2) which is contacted with the basal body (1) and a chromium oxide layer (3) which is arranged on the metallic chromium layer (2). The metal wire slit grating for developing stereo pictures which is not easy to be damaged and aged and is free from the limitation of the environmental condition has the advantage of long service life.

Description

Stereo-picture shows used metal wire slit grating

The utility model relates to a kind of stereo-picture and show used metal wire slit grating, its stereo-picture that is mainly used in various advertising propaganda materials, artistic products, decoration ornament, printed matter, stereoscopic photograph goods manifests.

Its cardinal principle is: when the strain line of grating and the strain line in the stereo-picture coincide, after the centre forms certain little gap, people's two eye pupil holes can receive respectively in the stereo-picture not in locational two the adjacent picture points of same image planes, be reflected in the spatial level true to nature that just can appear stereo-picture in people's the brain in one's mind, and moving the artistic effect that can produce animation in observing.

That sells on the market, home and abroad at present shows used slit grating product as stereo-picture, the product of climbing the production of skill company with the U.S. is an example, see shown in Figure 1: it is made up of organic glass matrix 1 and nonmetal light-sensitive surface 2 two parts that have chequered with black and white strain line, and they exist following shortcoming at large:

1, the strain line of slit grating is all made with nonmetal photosensitive material, and is fragile and aging, and serviceable life is short;

2, be subjected to the restriction of environmental baseline, should not be placed on outdoor and the relatively poor place of environmental baseline, usable range is narrow;

The purpose of this utility model provides a kind of long service life that has, and easy damaged and aging is not limited by environmental baseline, can be used in the metal lines slit grating that stereo-picture manifests widely.

The purpose of this utility model is achieved through the following technical solutions.

A kind of stereo-picture shows used metal wire slit grating, comprises the grating matrix (1) of clear, colorless float glass, and grating is made up of the chrome green layer (3) that the metallic chromium layer (2) that contacts with matrix (1) is positioned on the metallic chromium layer (2).The lenticular lenses profile is multiple structures such as circular, square, rectangle, triangle, ellipse, polygon.Grating is made up of individual layer chromium or individual layer chrome green or chrome-nickel alloy.Matrix (1) is made for clear, colorless organic glass or optical glass or clear, colorless crystal or clear, colorless synthetic material.

Brief Description Of Drawings.

Fig. 1 is the prior art of slit grating;

Fig. 2 is a metal wire slit grating of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing 2.

Shown in Figure 2, the utility model is the grating matrix with the float glass 1 of clear, colorless, on the grating matrix, use the combination rete of vacuum coating equipment evaporation last layer metallic chromium layer 2 and chrome green layer 3, on the combination rete, be coated with the last layer positive photoresist equably with glue spreader, after the oven dry of positive photoresist drying machine, be rotated on the super-huge litho machine with slit grating manufacturing mask plate and expose, in order to make strain line, develop among being put in the developing apparatus that fills sodium hydrate aqueous solution behind the formation latent image, after microscopic examination is qualified, be put in the dryer again and dry, after treating the dry sclerosis of positive photoresist film, put into again and fill potassium permanganate, corrode in the equipment of sodium hydrate aqueous solution, treat thoroughly to erode after exposed the chromium layer and chrome green layer, taking-up is removed the positive photoresist rete with sodium hydrate aqueous solution, dries after the water purification flushing, has so far just made solid figure and has shown used metal wire slit grating.

Claims
