Abstract: Results of an experimental study are presented for a working model of a joint-transform correlator with a liquid-crystal spatial light modulator at the input. Correlator operation with amplitude and phase modulation and various methods for joint power spectrum processing is compared to investigation results of the modelling partially performed earlier. A simple method is suggested for nonlinear processing of a joint spectrum, namely, limitation of its intensity by a photodetector.

Keywords: joint-transform correlator, nonlinear processing of a joint spectrum.
