Improved correlation discrimination using joint fourier‐transform optical correlator

Attempts are being made to investigate techniques to improve the cross-correlation peak heights of a joint-transform-based correlator while reducing the corresponding dc peaks. Two such techniques, namely, preprocessing the reference image and postprocessing the joint Fourier-transform image, are investigated, and the corresponding simulation results are compared.
