Growth-induced striations in photorefractive media constitute phase gratings that scatter
transmitted light and therefore degrade the quality of reconstructed images in holographic …

Growth-induced striations in photorefractive media scatter transmitted light, degrading their
performance in holographic applications. We model this phenomenon by considering the …

We consider the possibility of restoration and/or enhancement of decaying holograms in
photorefractive media by using a simple optical readout in conjunction with a phase …

We use photorefractive two-wave mixing for coherent amplification of the object beam in
digital holographic recording. Both amplitude and phase reconstruction benefit from the prior …

We propose a hologram multiplexing method with a speckled reference beam generated by
the photorefractive beam-fanning effect. In this method, a bulk photorefractive crystal takes …

We propose and demonstrate experimentally a new, phase-locked refreshment method for
reading out dynamic holographic photorefractive memories without destruction of the stored …

The dynamics of a composite grating that consists of an original grating and a newly
superimposed grating are investigated for memory applications by solution of coupled-wave …

We consider the possibility of restoration and/or enhancement of decaying holograms in
photorefractive media by using a simple optical readout in conjunction with a phase …

We explore theoretically and experimentally how application of an electric field to a
photorefractive crystal affects the recording and the readout of holograms. We consider, for …

We study detuning effects that modify the Bragg condition in photorefractive crystals and
analyze the influence of these effects on the retrieval of information that is stored in such …
