Paper Abstract

Optical correlator architectures have been reported which reduce the physical length of the conventional 4f design initially proposed by VanderLugt (1975). Attention is given to one such architecture which employs two simple lenses and obviates light collimation requirements. This 'modified 2f optical correlator' retains the highly useful Fourier transform scale feature; experimental correlation performance with a binary phase-only filter and photographic input is found to compare favorably with computer simulations of a 4f correlator.
