-
摘要: 本文介绍一种多通道的光学图象实时相关技术,它的特点是利用一个特制的多焦点重铬酸盐明胶全息透镜作为空间变异光学元件,以便产生多个光学通道並实现多图象的光学相关并行处理。文中介绍了这种多焦点全息透镜的特点与设计思想,以及它在实时多通道光学图象识别系统中的工作原理和若干实验结果。Abstract: This paper introduces a technique of real-time optical multi-channel correlation, which is achieved by using a specially designed dichromated-gelatin multi-focus holographic lens as a space-variant optical element. In addition, it describes the principles for designing such lens and the methhod for making it ns well as its working principles in the multi-image correlation system and some experimental results obtained from the system.
