摘要
在在相片的 holographicstorage 的一个批热的修理计划的光檫除动力学折射晶体理论上并且试验性地被调查。Theinter 批光檫除时间常数 T-F 被介绍指定光檫除到补偿栅栏，并且在一个复杂实验测量了。试验性的结果表演 thatT-F 比 intra 批长得多光檫除时间常数 T-E。差别 betweenT-F 和 T-E 为提高非不稳定的存储密度是基本的。
The optical erasure dynamics in a batch-thermal fixing scheme of holographic storage in photorefractive crystals is investigated theoretically and experimentally. The inter-batch optical erasure time constant τF is introduced to specify the optical erasure to compensated gratings, and measured in a sophisticated experiment. The experimental result shows that τF is much longer than the intra-batch optical erasure time constant τE. The difference between τFand τE is fundamental for enhancing nonvolatile storage density.
