| 摘 要： | 针对经典联合变换相关器的缺陷，提出了基于马赫—曾德尔干涉仪的单相关峰联合变换相关技术，输入图像通过马赫—曾德尔干涉仪的两臂无相对位移输入，实现互相关峰的重叠位于探测器中心。理论分析和实验表明，该方法不仅能获得高强度的单相关峰，而且能够降低系统成本，提高抗噪声能力，特别适合大尺寸图像的识别。

| Abstract: | An only-one correlation-peak joint transform correlator based on Mach-Zehnder interferometer is presented aiming at the shortcomings in the energy dispersion of correlation peak and of Classic Joint Transform Correlator(CJTC) the input image size and relative position to be restricted. The image input of proposed method has no relative displacement between input images by Mach-Zehnder interferometer, and realizes a high intensity overlap correlation-peak in the center of detector, so that the contradiction ... |
