Paper Abstract

We present theoretical analysis and experimental results of a white light JTC (joint transform correlator) using a tri- color grating to encode color patterns. The power spectra of the encoded pattern are easy for parallel channeling, and the zero order power spectrum also forms an important channel for the shape-only correlation.
