| 摘 要： | 二值化联合变换相关器，通过对联合变换的功率谱进行二值化操作可以提高联合变换相关器的图像识别。本文正是基于此观点，首次提出利用液晶光阀本身的饱和区实现反转二值化联合变换功率谱。

| Abstract: | Compared with the classic correlator, the binary joint transform correlator provides significantly higher peak intensity, larger peak to sidelobe ratio and narrower correlation width. Taking advantaging of the saturation property of liquid crystal light value (LCLV), we can obtain the inversed binary joint transform correlator. The experimental result is very satisfied. The all optical system is simple and easily operated. |
