摘　　要：制备了一种吖啶橙敏化的光致聚合物材料,并研究了材料的全息特性.用Ar+激光器三种波长的光对材料进行记录.结果表明,该材料具有较高的衍射效率、较高的曝光灵敏度和较大的折射率调制度,最大衍射效率均大于40%.将计算机二进制文件经过编码生成的二值图像存入样品,其再现图像较为清晰,译码后能够准确地还原出原文,表明该光致聚合物适合数字全息存储.A photopolymer material sensitized by acridine orange for holographic storage was fabricated,and the holographic characteristics were investigated. The material was illuminated by three wavelengths of Ar^＋ laser, and the results indicate that the material has high diffraction efficiency, high sensitivity and large refractive index modulation. The maximum diffraction efficiency under three wavelengths is more than 40%. A binary image which was coded with a binary file was stored in the sample and the reconstructed hologram had a good fidelity,which could be decoded into correct text. It is found that this photopolymer is appropriate for digital holographic storage.
