光折变晶体四波混频在图象实时加减及动态追迹显示中的应用

Application of FWM photorefractive crystals in image real-time addition,subtraction and dynamic tracking display

本文提出了利用两个四波混频相位共轭反射镜的Michelson干涉仪系统进行图象加、减、图象强度反转以及动态追迹显示的理论依据和实验方案,并获得了理论分析与实验现象一致的结果,证明了这种方法的可行性。

The theory analysis and experimental set-up of the opti- cal image addition, subtraction, intensity inversion and dynamic trac- king display are presented. The experimental set-up is a Michelson in- terferometer containing two four-wave-mixing phase conjugate mirrors. The experimental results are well accordant with the theory analysis.
