1．引言全息存储早在六十年代中期就被人们所认识,由于材料的局限性,以及光电器件远远不能满足全息存储处理的要求,其发展非常缓慢。然而,到了九十年代以后, 已今非昔比,全息存储材料及光电子器件等有了很大的发展,例如为提高存储密度而采用先进的PCM复用技术;材料如有机光致聚合薄膜和有机光折变薄膜的应用研究于1994年以后有了很大发展;小型、低价、稳定、
1. Introduction Holographic storage was recognized as early as the mid-1960s and has been slow to develop due to material limitations and the unavailability of optoelectronic devices for holographic storage. However, since the 1990s, great progress has been made in the field of holographic storage materials and optoelectronic devices. For example, advanced PCM multiplexing technology is used to increase the storage density. Materials such as organic photopolymerizable films and The application research of organic photorefractive films has been greatly developed since 1994. The small, low-cost, stable,
