Multitarget Detection Using a High-efficiency Hybrid Optical Joint Transform Correlator

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。

The technique for multitarget detection using a high-efficiency hybrid optical joint transform correlator is proposed. In this technique, N copies of the joint power spectrum are made and N identical joint power spectral array is constructed. This technique can effectively make use of the areas of the spatial light modulator as well as the efficiency of the read out light, so that an enhanced optical correlation signal can be obtained at the output plane.
