We investigate the enhancement of the diffraction efficiency of dynamic gratings recorded in
a bismuth silicon oxide crystal at large modulation by the moving-grating technique. The …

The technique of moving gratings in a photorefractive crystal is applied to the edge
enhancement of objects and edge-enhanced optical correlation. The nonlinear dependence …

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 …

Real-time edge-enhanced image correlation using the incoherent readout of a dynamic
hologram recorded in BSO crystal is reported for the first time. A system is described which …

A new technique for optical correlation using gated holographic recording is demonstrated.
Several persistent holograms are localized within separate slices as close as 33 μm apart …

Real-time cross correlation between two transparencies using photorefractive Bi 12 SiO 20
