Hardened gelatin films sensitized with ammonium dichromate can be utilized to record high quality holograms. The maximum diffraction efficiency of the hologram approaches 90%. The light scattering from the hologram is so low that under ordinary light the hologram plate appears almost indistinguishable from a clear glass plate. Either a transmission or a reflection hologram can be recorded. Linear recording range of light amplitude is large. A practical method of preparing and processing the film is described, and the exposure characteristics are presented.
用重铬酸铵敏化的硬化明胶膜可用于记录高质量全息图。全息图的最大衍射效率接近90%。全息图的光散射非常低，以至于在普通光线下，全息图板看起来几乎与透明玻璃板没有区别。透射或反射全息图均可记录。光振幅的线性记录范围很大。本文描述了一种制备和处理该膜的实用方法，并给出了曝光特性。
