A joint transform correlator (JTC) using photorefractive Bismuth Silicon Oxide (BSO) as a
nonlinear recording medium, and a liquid crystal television (LCTV) as a spatial light …

A photorefractive optical correlator capable of recognizing objects regardless of their
position, rotation, or scaling in Cartesian space is described and demonstrated. This work is …

Two input real-time optical correlation using photorefractive media is discussed.
Consideration is given to the bearing of the input arrangement on the correlator's response …

A four-wave mixing (FWM) optical correlator created by using a thin photorefractive (PR)
bismuth silicon oxide (BSO) crystal plate is demonstrated. The envelope function which …

An experimental implementation of a joint transform correlator based on a nondegenerate
four-wave mixing interaction in the photorefractive material bismuth silicon oxide is …

A real-time optical correlator based on GaAs and liquid-crystal TV (LCTV) is demonstrated.
The demonstrated system has a video-frame rate limited by the speed of the LCTVs; if faster …

The use of photorefractive materials such as Bi 12 SiO 20 as dynamic holographic media is
becoming an interesting alternative to that of the current liquid-crystal-based modulators in …

The optical cross correlation of an image with another image that was spatial-frequency
shifted in one dimension was demonstrated in a photorefractive VanderLugt correlator. The …

A high speed optical correlator is presented in this paper. It is a joint transform correlator
using a BSO photorefractive crystal in the Fourier plane. The performance of the system …

The joint transform correlator (JTC) is well known to be one of the most convenient devices
for correlating two images in the sense that there is no need to fabricate a holographic filter …
