The Relation Between Property of High Density Volume Holographic Storage

摘要: 讨论了影响高密度体全息存储性能的动态范围、衍射效率均匀性及布拉格选择灵敏度等三个参量与几何组态之间的关系，强调三者均衡考虑在光路配置中的重要性。利用该均衡原则对LiNbO3晶体进行分析，指出采用O光耦合的90°写入光路为其最佳的几何配置。

Abstract: The relation between parameters (including dynamic range, uniformity of diffraction efficiency and Bragg selectivity), Which will affect the performance of highdensity volume holographic storage, and geometric conffiguration is discussed. The importance of the three parameters of balanced consideration in the beampath configuration is emphasized. According to the analysis of LiNbO3 crystal with the principle of the balance, it is pointed out that the 90° writing beampath with Olight coupling is the best geometic configuration.
