Study on holographic characters of two Dyes co-sensitized water-resisting photopolymer

报道了一种新型、双染料共同敏化的非水溶性光致聚合物全息记录材料。该材料由复合单体、复合光敏剂、复合引发剂、链转移剂及成膜物等成分组成,具有防潮、后处理简单、分辨率高、体积收缩小及耐高温等特点。材料能够同时对红、绿光敏感,对两种光的衍射效率均不低于75%,灵敏度均不低于0.025cm2/mJ。存储结果显示,再现图像清晰明亮,信噪比高,说明该光致聚合物具有较好的存储性能,适合双波长复用全息存储。

A novel type of water-resisting photopolymer holographic recording material co-sensitized by two dyes is presented.The photopolymer material consists of compound monomers,compound sensitizers,compound initiators,chain transfer agents,and binders,etc.The material has properties of waterproof quality,simple later development,high resolution and high temperature stability,etc.The photopolymer is sensitive to red light and green light simultaneously.Diffraction efficiencies are no less than 75%,and sensitivities are no less than 0.025 cm^2/mJ when exposed to red light and green light respectively.The reconstruction images are clear and bright,and the signal-to-noise ratio is very high,which indicates that the photopolymer is promising to two-wavelength multiplexing holographic storage.
