提出一种使用高效光电混合的联合变换相关器作多目标检测的方法。这一方法将联台功率谱复制N份构成N个全同的联合功率谱列阵，可以更有效地利用空间光调制器的面积以及读出无效率，因而在输出面可获得增强的光学相关信号。
A multi-target detection method using a joint transformation correlator with high efficiency photoelectric hybrid is proposed. This method replicates the joint power spectrum to N to form N identical power spectrum arrays, which can make more efficient use of the spatial light modulator area and the readout inefficiency so that an enhanced optical correlation can be obtained on the output surface signal.
