摘　　要：光致聚合物是一种新型的全息材料,相比于常规的银盐材料、重铬酸盐明胶等,具有光学性能好、性能价格比高、支持大规模生产等优势。本文首先介绍了光致聚合物的制备方法,随后分别从角度复用存储、二维正弦光栅直写、全息图像记录等方面,概述了基于光致聚合物的全息显示技术要点。随后对比了传统材料卤化银乳胶和新型材料光致聚合物的信息存储性能,结果表明光致聚合物衍射效率更高,且不需要后湿化学处理,综合应用效果更好。Photopolymer is a new type of holographic material.Compared with conventional silver salt materials,dichromate gelatin,etc.,it has the advantages of good optical properties,high cost performance,and support for large-scale production.This paper firstly introduces the preparation methods of photopolymers,and then summarizes the technical points of holographic display based on photopolymers from the aspects of angle multiplexing storage,two-dimensional sinusoidal grating direct writing,and holographic image recording.Then,the information storage properties of the traditional material silver halide latex and the new material photopolymer were compared.The results show that the photopolymer has higher diffraction efficiency,does not require post-wet chemical treatment,and has better comprehensive application effect.
