REAL-TIME INTENSITY CORRELATION WITH A SYNTHETIC DISCRIMINANT FUNCTION FILTER

Real-time optical intensity correlation with a synthetic discriminant function (SDF) filter has been realized. The computed SDF data are fed into an Epson liquid-crystal television to create the optical referen ce signal. The intensity modulation characteristics of the Epson liqui d-crystal television are therefore investigated in the different modul ation modes. The difficulties of generating the SDF filter, which are due to the negative values in the SDF data and to the characteristics of the spatial light modulator, are readily overcome by use of an inte nsity correlator. Experimental results are presented.
