银盐明胶计算全息图的软模复制方法研究

The Duplication Method for Silver Halide (sensitized) CGH Using the Soft Dies

提出一种复制银盐计算全息图（SHCGH）的新方法，在SHCGH母板上浇注一张橡胶软模板，软模再经第二次浇注，将CGH浮雕结构转移到各种物件表面。对复制品与母板的浮雕深度转移进行了测量，并通过选择第二次浇注材料，改善了复制品的光学再现效果。

A method of duplication for silver halide sensitized CGH (SHCGH) is shown in this paper. The first procedure is that a soft die is poured at the surface of SHCGH to use the rubber,and the second is that the relief structure of the SHCGH is duplicated by the medium. It can be duplicated to the surface of any other articles. In this paper,the relief depth of reproduction and original of CGH has been measured,and the optical reconstruction effect of CGH has been improved by selecting the second pouring medium.
