全色光致聚合物的全息记录 特性及应用研究

优选亚甲基蓝、曙红Y、吖啶橙分别作为红敏、绿敏、蓝敏光敏剂,制作出全色光致聚合物全息记录材料.全息记录特性测量表明,该材料在红、绿、蓝三基色激光记录下均具有大于90%的衍射效率和较高的感光灵敏度(70 mJ/cm²).开展了该材料的角度复用、波长复用全息存储实验,在材料的同一位置处分别以不同参物光夹角及不同记录波长成功存储了多幅全息图,且再现图像清晰明亮,相互之间无明显串扰,表明该材料具有良好的全息记录性能及应用价值.

Research on the Holographic Recording Characteristics and Applications of a Panchromatic Photopolymer

By selecting Methylene blue,Eosin Y and Acridine Orange as red-,green-and blue-sensitive photosensitizers respectively,a water-soluble panchromatic photopolymer is fabricated successfully.This material has high diffraction efficiency(over 90%) and high photosensitivity(~70 mJ/cm2) for three primary color lasers.Angular and wavelength multiplexing holograms are successfully recorded in the same location of the panchromatic photopolymer,the reconstructed multicolor images are clear and bright,and there is no obvious crosstalk between them.The experimental results show that this panchromatic photopolymer material has good holographic recording characteristics and application prospects.
