STUYD ON THE EXPOSURE PROPERTIES OF KTD SILVER HALIDE HOLOGRAPHIC PLATE

本文首先对用ＫＴ－Ｄ型银盐全息干版记录的全息图的曝光特性进行了实验研究，获得了全息图的衍射效率与曝光能量的关系曲线．然后应用Ｋｏｇｅｌｎｉｋ的耦合波理论测算出乳胶折射率及其调制度的曝光特性，对其折射率调制机理作出必要的理论分析，并获得了ＫＴ－Ｄ型全息干版的性能参数．

n this paper firstly the exposure properties of holograms in KTD silver halide holographic plate are studied experimentally. The relation curve between the diffraction efficiencies of the holograms and the exposure energy are given. Then the average refractive index of silver halide emulsion and refractive index modulation of the holograms are estimated based on Kogelniks coupled wave theory for volume holograms. After that, the mechanisms for forming refractive index modulation in the holograms are analyzed theoretically. Finally the performance parameters of KTD silver halide holographic plate are obtained.
