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 …

We present an experimental implementation of a packaged free-space optical
interconnection system by photorefractive correlation. The system consists of a phase code …

An optical photorefractive frequency-domain method is described for measuring
displacement amplitude and phase of vibrating surfaces. The method is applicable to …

We describe initial experiments on a photorefractive-based optical image correlator which
employs a frequency-doubled, pulsed Nd: YAG laser with a pulse length of 10 ns to write a …

Photorefractive time-integrating correlator using BSO 1 and BaTiO 3 2 have been
demonstrated previously. They have potential uses in radar pulse compression and …

We solve the problem of the transmission of time modulated signals in a two-beam coupling
photorefractive set-up using an absorbing material. We obtain an analytical expression that …

When photorefractive materials are included as elements in image and signal processing
systems, the dynamic range of the photorefractive element has a significant impact on the …

An updatable optical correlator which uses a photorefractive compound semiconductor to
generate real-time matched filters is proposed. Using compound semiconductors offers high …

A photorefractive two-beam-coupling based novelty filter is sensitive to amplitude and phase
changes. However, the phase sensitivity of this device has remained unexploited until now …
