摘　　要：偶氮液晶聚合物 (L CP)是一种新型的光存储材料。本文介绍了偶氮 L CP中的双光子光致双折射效应 ,提出了基于偏振角度复用法在偶氮 L CP中进行多灰阶存储的基本原理、方法和技术 ,给出了灰阶存储的原理性实验结果 ,设计了偶氮 LAzo liquid crystal polymer (LCP) is a novel optical storage medium.In this paper,we introduced two photon induced birefringence effect in azo LCP.Based on the method of polarization angle variation,a multi scaled storage technology was proposed.The experiment result of multi scaled storage was demonstrated,and an optical system scheme for the multi scaled memory was suggested.
