Photochromic effects in crystals of photorefractive bismuth silicon oxide have been used for the recording of permanent holograms. The combination of this permanent recording with the usual photorefractive real time recording has revealed some novel techniques in information processing and interferometry. These are based on the possibilities of multiplexing two distinct holographic gratings having identical grating wave vectors within the same crystal volume. Techniques ranging from image synthesis and logic operations to holographic interferometry and all-optical switching are demonstrated.
光折变氧化铋硅晶体中的光致变色效应已被用于永久全息图的记录。这种永久记录与通常的光折变实时记录相结合，揭示了信息处理和干涉测量中的一些新技术。这些技术基于在同一晶体体积内复用具有相同光栅波矢的两个不同全息光栅的可能性。展示了从图像合成、逻辑运算到全息干涉测量和全光开关等技术。
