DYNAMICS OF HOLOGRAM READOUT IN PHOTOREFRACTIVE CRYSTALS FOR BROKEN …

We propose a mathematical model for the movement in absorbing materials of
photorefractive holograms under feedback constraints. We use this model to analyze the …

Several methods are investigated to avoid undesired erasure during read-out of volume
phase holograms stored in photorefractive crystals. We present results on thermal fixing and …

We report a new improved procedure for experimental data fitting in photorefractive fringe-
locked running hologram experiments. From this fitting we compute the diffusion length LD …

We report a theoretical model for a photorefractive running hologram in bulk-absorbing
materials in the presence of self-diffraction and use this model to analyze experiments for …

We report on the nonlinear relation between the resonance hologram velocity and the
recording light irradiance in fringe-locked running hologram experiments carried out on a …

Holographic gratings in photorefractive crystals that are based on charge redistribution
inevitably decay as a result of ionic and electronic conduction. Under certain and restricted …

We report on the recording of stabilized running holograms in photorefractive materials with
arbitrarily selected phase shift φ between the transmitted and difracted beams propagating …

We report the use of Lloyd's mirror interferometer for holographic recording in
photorefractive material. The experimental results show that perturbations in the diffraction …

Certain memory applications based on photorefractive media require the ability to
conveniently fix holograms. An attractive alternative is to sufficiently prolong the readout …
