多通道实时光电混合联合变换相关器

Multi-Channel Real-Time Hybrid Joint Transform Correlator

提出一种多通道实时光电混合联合变换相关器 ,其中用一个液晶光阀 ( LCL V)作为非相干——相干图象转换元件 ,用一个多通道全息透镜阵列作为付氏变换元件实现多通道联合变换相关。这种相关器有效地利用了液晶光阀的有效使用面积和读出光能量 ,提高了相关识别性能。文中给出了实验结果。

A multichannel realtime hybrid joint transform correlator is proposed in this paper. By the use of the liquid crystal light valve (LCLV) as a incoherenttocoherent conversion device and the multichannel hololens array as a fourier transform element, multichannel joint transform correlation has been implemented in time. In this correlator, the areas of the LCLV and the output light energy can be used effectively, the correlation performance can be improved. The experimental results are given.
