摘要
本文研究了一种偶氮染料——明胶体系的偏振全息记录材料的特性,它具有实时记录,可重复使用,衍射效率高(>30%),保存期长,所需阀值激光功率低等特点.此外还研究了衍射效率与偏振状态的关系,给出了详细的研究结果.
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.
