1 September 1990 Optical pattern recognition with phase-only circular harmonic filtering
Author Affiliations +
Optical demonstration of phase-only circular harmonic filtering using a binary CGH in a standard Fourier transform correlator is reported here. The experimental results have confirmed the computer simulated results1 in that the phase-only circular harmonic filtering produces smaller side-lobes and more prominent correlation peaks with the target.
