用调制度评价卤化银乳胶全息记录材料的特性

Evaluation of silver halide recording material by measuring phase modulation

为了测定卤化银乳胶全息记录材料的特性，传统方法通常是测定其光密度Ｄ，衍射效率η和信噪比ＳＮＲ等与曝光量、光束比或条纹可见度等参量之间的关系。本文采用了一种利用位相调制度评价全息记录材料的特性的方法。它有助于更全面、更透彻地了解卤化银乳胶对于拍摄全息图的主要性能。

To evaluate a silver halide holographic recording material by measuring its optical density D,diffraction efficiency η and signal noise ratio SNR to obtain their relationships with exposure,beam ratio and fringe visibility is a conventional method in holography.In this paper,a new method is proposed for evaluation of a silver halide holographic recording material by testing phase modulation together with D,η and SNR.This method is helpful for a perfect understanding of the main characteristics of a silver halide holographic recording material in making a hologram.
