A new, dry method for converting photographically recorded amplitude holograms to high diffraction efficiency phase holograms is described. The dry method involves the application of elemental bromine or chlorine. The bromine vapor bleaching of transmission holograms produced efficiencies of 70.8% in dry film and 75.5% in water swelled layers. Index modulations of 0.033 have been observed. Reflection hologram efficiencies of 73% were obtained. The stability of the bromine vapor bleached holograms to printout is superior to all previous methods.
描述了一种将照相记录的振幅全息图转换为高衍射效率相位全息图的新型干法。该干法涉及使用元素溴或氯。透射全息图的溴蒸汽漂白在干膜中的效率为70.8%，在水溶胀层中的效率为75.5%。已观察到折射率调制为0.033。反射全息图的效率达到了73%。溴蒸汽漂白全息图对打印输出的稳定性优于所有先前的方法。
