基于丙烯酰胺基单体的光聚物的全息特性

The Holographic Characteristics of the Photopolymer Based on the Monomer Acrylamide Radicel

用实验的方法研究了由丙烯酰胺和亚甲基双丙烯酰胺构成的光致聚合物(光聚物)的全息性能。实验表明,这种由藻红染料敏化的光聚物具有较高的衍射效率、折射率调制度、曝光灵敏度和动态范围,分辨率可达3000lines/mm,是高密度全息存储所需的比较理想的位相型存储材料。

The holographic characteristics of the photopolymer based on the acrylamide radicel monomers are studied with experimental methods.The results show that this kind of photopolymer that sensitized with erythrosine B has high diffraction efficiency (68 %),high refractive index modulation (2.2×10-3),large dynamic range (39),and high exposure sensitivity (1×10-2 cm2/mJ),the resolution of the sample reaches 3 000 lines/mm.This indicates that this kind of photopolymer will be the most appropriate candidate in the future holographic system.
