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 properties of photopolymers (photopolymers) composed of acrylamide and methylenebisacrylamide have been investigated experimentally. Experiments show that the photo-polymer sensitized by phycoerythrin dyes has high diffraction efficiency, refractive index modulation, exposure sensitivity and dynamic range with a resolution of up to 3000 lines / mm, which is the required comparison for high-density holographic storage Ideal phase-type storage material.
