从实验上研究了亚甲蓝敏化液浓度对明胶透射全息光栅的衍射效率的影响。在有氧环境下，以６３２．８ｕｍ的Ｈｅ－Ｎｅ激光束曝光并以简单工艺作后处理，获得了高达９７％的衍射效率。
The effects of methylene blue sensitizer concentration on the diffraction efficiency of gelatin transmission holographic gratings were experimentally studied. Under aerobic conditions, exposure to a He-Ne laser beam of 632.8 um and post-processing in a simple process yielded diffraction efficiencies of up to 97%.
