摘要/Abstract

摘要： 甲基紫掺杂聚乙烯醇薄膜材料在两柬相干光照射下生成相位光栅．当改变一束相干光光程，通过监测相位光栅的一级衍射信号强度的变化，可以检测相位光栅的生长和擦除过程．在此实验基础上，讨论了甲基紫掺杂聚乙烯醇薄膜材料多重全息存储的原理与结果．

关键词: 甲基紫掺杂聚乙烯醇, 相位光栅, 多重全息存储

Abstract: Methyl violet dyes doped polyvinyl membrane build phase grating under two branchs of coherent beams irradiation. While changing one branch the range of one coherent light, the growth and erasure process of the phase grating can be examined through monitoring the changes of first order diffraction light intensity. The theory and experimental results are provided.

Key words: methyl violet dyes doped polyvinyl membrane, phase grating, multi-holographic memory
