双波长敏感的非水溶性光致聚合物全息存储性能和应用研究

Study on Holographic Characters and Application of Two-Wavelength Sensitive Water-resisting Photopolymer

文中报道了一种新型的对红绿光敏感的非水溶性光致聚合物体系,并对光致聚合物的高密度全息存储性质和应用进行了研究.实验证明我们用复合单体和复合增感染料制作出的这种全息干版保存期长,适于拍摄反射式全息图,拍摄出的全息图明亮、清晰,保真度好.并用此光致聚合物制作了全息光栅,其衍射效率可达80%,分辨率超过4 000 cy/mm.

The paper reported a new type of two-wavelength sensitive water-resisting photopolymer system that is sensitive to the red light and the green light.The photopolymer material consists of compound monomers,compound sensitizers.we have studied the application and holographic storage nature of this photopolymer.The reflection holograms made of this material have hight diffraction efficiency and clarity.We used this materials made holographic grating,it＇s diffraction efficiencies are no less 80%,and resolutions are more than 4 000 cy /mm.
