We present an optical time-delay line based on photorefractive beam coupling in a rotating
crystal. The delay line can be tapped continuously or at selected positions. We demonstrate …

We propose and demonstrate a new configuration of a photorefractive time-integrating
correlator system using acousto-optic devices to process rf signals. In our system, two rf …

We have experimentally demonstrated a single-beam interferometer that effectively
subtracts an exponentially weighted history of the input from the current value, thus …

We describe two-beam coupling and temporal encoding experiments in barium titanate.
Volume gratings are created in the photorefractive material by 50-fs optical pulses …

We demonstrate a self-organizing photorefractive circuit that demultiplexes a beam that has
two signals imposed on separate optical carrier frequencies into two beams, each …

A photorefractive time correlation motion detector is demonstrated. This device overcomes
the material response time limitation associated with other photorefractive motion detectors …

A real-time image processing technique has been described, using a two-beam coupling
geometry in photorefractive materials. An erase beam copropagating with the signal beam …
