Selected Papers on Optical Pattern Recognition Using Joint Transform Correlation

SPIE Milestones are collections of seminal papers from the world literature covering important discoveries and developments in optics and photonics.

The motivation of this work was to introduce all-optical holographic techniques to
complement other optoelectronic techniques in a nonlinear correlator. These
correlators are improved by replacing the various serial computational algorithms
in the Fourier plane (used in optoelectronic correlators3-10) with an optically
addressed nonlinear device. The first implementation of the nonlinear
optoelectronic joint transform correlator (JTC) used binarization of the joint power
spectrum with a ...
