自1963年发现了霜面成像的照像方法以后,光导热塑记录材料构了很大的发展。因为它的灵敏度、分辨率、衍射效率均比较高,受到了研究和使用人员的重视,因此对光导体进行了相当深入的研究。但是对光塑全息片中影响使用的一个重要问题,即记忆效应却缺乏系统的研究。文献上有关记忆效应的报导是互相矛盾的。主要有两种看法,一 Since 1963, the discovery of the frost image imaging method, the photoconductive thermoplastic recording material structure has been greatly developed. Because of its sensitivity, resolution, diffraction efficiency are relatively high, has been the research and user attention, so the light conductor has been a very deep study. However, one of the most important problems affecting the use of optical plastic hologram is that there is no systematic study on the memory effect. The literature on memory effects is contradictory. There are two main ideas, one
