摘要
报导了一种新型的对绿光敏感的光致聚合物材料。该材料以丙烯酰胺为单体 ,由光引发剂 ,共引发剂 ,成膜物等组成。本材料记录的全息图衍射效率可达 5 5 %。在光聚物上采用角度复用技术存储了 10幅图像 ,得到的再现像信噪比较高。说明该材料适合于大容量体全息存储。
A new type of green light sensitive photopolymer material is prepared. The photosensitive medium is composed of acrylamide monomer, photoinitiator, coinitiator and polymeric film forming binder. With holograms recorded in this material, the diffraction efficiency of the photopolymer as high as 55% is obtained. 10 holograms are stored in this medium using angular multiplexing technology and the SNR of the reconstruction images is high. It proves that the photopolymer is suitable for high density volume data storage.
