反射全息乳胶特性的一种检测方法

A testing method for evaluation of emulsion characteristics for reflection hologram

本文提出一种检测反射全息乳胶特性的方法。它通过检测拍摄反射光栅时所伴随产生的透射光栅的位相调制度来间接判断反射光栅的性质。实验表明：透射光栅的位相调制度与曝光量的关系与反射光栅衍射效率与曝光量的关系两者间有很好的对应，而透射光栅的位相调制度是易于检测和控制的，因而可以借助于它来掌握或控制反射光栅的衍射效率。本文给出了理论分析和实验结果。

A new testing method is proposed for evaluation of holographic materials for reflection hologram.Properties of a reflection grating can be judged by testing the modulation of the transmission grating which is generated at the same exposure in making the reflection grating.Expeiments show that there are certain relations between the efficiency of the reflection grating and the modulation of the transmission grating.Modulation of a transmission grating is easy to measure and control,so we can makd an expectation efficiency reflection holographic grating with the help of this method.Theoretical analysis and experiment trsults are given.
