卤化银明胶全息图的空间频率响应
Spatial Frequency Response of Silver Halide Gelatin Holograms
摘要
对用国产(天津Ⅰ型)卤化银全息干板制作明胶全息图时的空间频率响应特性进行了实验研究。当空间频率在500~800 lines/mm之间时,获得了峰值衍射效率大于70%的明胶全息图.此外,将通常的三步脱水法简化为一步脱水,同样可获得高衍射效率的明胶全息图。给出了这种全息图的制作过程及实验结果,并从微观机制上说明了一次性脱水的理由.
Abstract
A study on spatial frequency response of silver halide gelatin holograms derivedfrom Tianjin-I plate of China is carried out experimentally.When the frequency is limitedwithin 500~800 lines/mm,the holograms with higher than 70% peak diffractionefficiency are obtained.In addition,with one-step dehydration of the gelatin hologramsiusted of the three-step used usually,the holograxns with high difftaction efficiency canalso be obtained.In this paper,the making procedure and the experimental results of the holograms are presented, and the reason that only one-step dehydration is necessary is explained.
