A multi-target detection system based on joint transform correlator for amplitude-modulated electro-optical mixing is proposed. This structure belongs to the joint transform correlator of the programmable single spatial light modulator. To improve the resolution of the system and the space-bandwidth product, a programmable single-spatial light modulator consists of a liquid crystal display, an imaging lens, and a liquid crystal light valve. This method has the advantages of optical processing signal is parallel, large capacity and high speed, and the flexibility and programmability of the computer to deal with the joint power spectrum. The experimental results confirm the correctness of the multi-target detection by the combined transform correlator of the photo-electric hybrid modified amplitude modulation.
