Paper Abstract
It has been shown previously that the binary joint transform correlator (JTC) can produce reasonably
good correlation performance.'5 The binary JTC uses nonlinearity at the Fourier plane to binarize the Fourier
transform interference intensity to only two values, +1 and -1. The binarization is performed according to a
predetermined threshold value which is the median of the joint power spectrum histogram. The performance of
the binary JTC was compared to that of the classic JTC in the areas of light efficiency, correlation peak to
sidelobe ratio, correlation width, and cross-correlation sensitivity. It was shown that compared with the classical
correlator, the binary joint transform correlator provides significantly higher peak intensity, larger peak to
sidelobe ratio, narrower correlation width, and better cross-correlation sensitivity.
