【摘要】 利用超短光路结构和空间折叠光路结构,研制出一种小型多功能光学相关器,它能高速处理256×256像素图像。光学相关器易上下拆卸,并方便地实现Vander Lugt相关和联合变换相关之间的互换。实验结果证实了该系统具有较好的相关性能。更多还原

【Abstract】 A small-sized multi-function optical correlator that can process 256256 pixels image is developed by means of ultra-short beam path structure and space folding beam path structure. The optical correlator can be easily dismounted from the top and the bottom. The interchange between Vander Lugt correlation and joint transform correlation can be conveniently carried out. The experimental results demonstrate that the system has a better correlative performance.更多还原
