A real-time coherent optical correlator is described that uses the Itek PROM as a recyclable filter recording medium. Operation of a joint transform correlator is compared to a conventional Vander Lugt system. Experimental results are shown for the joint transform system, including demonstrations of the effects of target alignment and scale and the correlation of random bit rasters for signal processing applications.
本文描述了一种实时相干光学相关器，它使用Itek可编程只读存储器作为可循环使用的滤波器记录介质。将联合变换相关器的操作与传统的范德卢格特系统进行了比较。给出了联合变换系统的实验结果，包括目标对准和比例效应的演示以及用于信号处理应用的随机比特光栅的相关性。
