通过在明胶层中引入新型多色光敏剂及光化学增感助剂,成功研制出了三基色感光度达30 mJ/cm^2、衍射效率大于85%和分辨率大于5 000 lines/mm的全色铬酸盐明胶全息记录新材料.对其配方构成、光谱响应曲线、三基色感光灵敏度、反射体全息光栅的光谱选择性、透射体全息光栅的角度及波长选择性等特性进行了报道,对其在真彩色全息显示、角度复用波长复用全息存储等的初步应用结果作了简要的介绍.
By employing new types of multi-color photosensitizers and photochemical promoters to conventional photocrosslinking gelatin system, a high-quality single-layer panchromatic chromate gelatin material is successfully achieved. Its characteristics such as spectral response, photosensitivity of three primary colors, spectral selectivity of volume reflection hologram,angular and wavelength selectivity of volume transmissioin hologram, are studied in detail. Some preliminary experimental results in true-color reflection holography,angle and wavelength multiplexing holographic storage are also reported in this paper.
