Paper Abstract

An experimental investigation is conducted of joint-power spectrum nonlinear transformation effects on the performance of a joint transform correlator. Attention is given to correlation-peak intensity, SNR, peak/sidelobe value, and peak width, for various degrees of the nonlinearity employed at the Fourier plane. The results obtained indicate increases of peak intensity, SNR, and peak/sidelobe, in conjunction with a decrease of the correlation, as the severity of the joint power spectrum''s nonlinear transformation increases. Attention is given to the performance of the liquid crystal light-valve spatial light modulator employed.
