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。
In order to determine the characteristics of a silver halide emulsion holographic recording material, the conventional method is usually to determine the relationship between the optical density D, the diffraction efficiency η, the SNR of the signal to noise ratio, and the parameters such as the exposure amount, the beam ratio or the streak visibility. In this paper, we adopt a method that uses the phase modulation to evaluate the characteristics of a holographic recording material. It helps to have a more complete and thorough understanding of the key properties of a silver halide emulsion for taking holograms.
