5 May 2014 Performance evaluation of photorefractive two-beam coupling joint transform correlator
Author Affiliations +
The performance of a novel joint transform correlator (JTC) based on photorefractive (PR) two-beam coupling (TBC) is analyzed by determining the dependence of relevant figures of merit such as the discrimination ratio, the peak-to-correlation plane energy ratio, and the peak-to-noise ratio on the PR gain coefficient and pump-probe beam ratio for a variety of reference and signal images. In this scheme, spatially separated reference and signal images constitute the pump, which transfers energy to a weak probe in a novel image processing setup where the PR polymer serves as the spatial filter in the Fourier plane.
