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。
This paper presents a method to detect the characteristics of reflective holographic latex. It indirectly determines the properties of the reflection grating by detecting the phase modulation of the transmission grating generated when the reflection grating is photographed. The experimental results show that the relationship between the phase modulation of the transmission grating and the exposure and the relationship between the diffraction efficiency of the reflection grating and the exposure are in good agreement. The phase modulation of the transmission grating is easy to detect and control, To grasp or control the diffraction efficiency of the reflective grating. This paper gives the theoretical analysis and experimental results.
