联合变换相关技术的初步研究

对联合变换相关技术进行了理论分析,采用液晶光阀(LCLV)、CCD 相机等器件设计了一套单光路、光寻址、双空间光调制器联合变换相关实验系统、进行了单目标、多目标、噪声图像识别的实验研究,测试了系统对图像畸变的敏感性,实验研究了液晶光阀(LCLV)的非线性输入——输出特性对相关结果的影响,最后初步探讨了联合变换相关器畸变——不变图像识别的方法。

Optical/Electronic Hybrid Joint Transform Correlator Research

In this paper,Joint Transform Correlation technique is discussed,and Joint Transform Correlator experimental system with two optically addressed SLMS is designed.A series of experimental results have been obtained,including single target,multiple targets and noisy image recognititon.We have measured the image distortion sensitivity of this system,and the effects of LCLV'S nonlinear input-output character on correlation signds. Finally we have concisely discussed the way of ditortion-invariant image recognition by Joint Transform Correlator.
