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 multi-channel real-time hybrid opto-electronic hybrid correlator is proposed, in which a liquid crystal light valve (LCL V) is used as a non-coherent-coherent image conversion element and a multi-channel holographic lens array is used as a Fourier transform element to achieve multi- Transform related. This correlator effectively utilizes the effective area of the liquid crystal light valve and the readout light energy, improving the correlation performance. The experimental results are given in the paper.
