B. Javidi et al., BINARY NONLINEAR JOINT TRANSFORM CORRELATOR PERFORMANCE WITH DIFFERENT THRESHOLDING METHODS UNDER UNKNOWN ILLUMINATION CONDITIONS, Applied optics, 34(5), 1995, pp. 886-896
The correlation performance of binary joint transform correlators with
unknown input-image light illumination is investigated for different
thresholding methods used in the Fourier plane. It is shown that a bin
ary joint transform correlator that uses a spatial frequency dependent
threshold function for binarization of the joint power spectrum is in
variant to uniform input-image illumination. Computer simulations and
optical experimental results are provided.
