散射光输入的联合变换相关方式研究

Joint Transform Correlation Using Diffused Light as Input Illumination

针对联合变换相关器在频谱面上光能利用率和面积利用率不高的特点 ,本文提出了一种新型的联合变换相关方式 ,利用散射光代替平行光输入图像 ,实验结果表明该方法能均匀地使用频谱面上的面积 。

For the ordinary joint transform correlator,it′s utilization ration of luminous energy and of area in the spectrum plane are not high.In view of this character,a new joint transform correlation fashion is put forward in this paper.Parallel light is replaced by diffused light as input illumination.The experimental results show that the method presented in this paper can use homogeneously the area in the spectrum plane and high brightness image of joint transform correlation is obtained.
