【Abstract】 The property of azo-dye-gelatin for polarization holographic recording is investigated. Besides the characteristics of real time recording and reversibility, it possesses the properties of high diffraotion efficiency, long-storage time and comparative low laser power needed for recording. The dependence of diffraotion efficiency on polarization state is studied in detail.更多还原
