摘要
本文叙述了Joint变换的基本原理,并利用液晶光阀的偏振调制特性实现了Joint变换,液晶光阀作为实时记录器件,可以对物体的频谱进行改善,从而得到了较好的相关输出,实验结果与理论分析相符,提供了实时光学相关的一种新方法。
The basic principle of joint transform is described. Joint transformis realized by suing the polaried modulation charac-teristics of LCLV.As areal-time recording element,LCLV may improve the power spectrum of objectsto get better correlation output. Anew method for real-time optical correlationis given. The results are consistent with the theory analysis.
