Stabilized selective photorefractive holographic erasure
نویسندگان
چکیده
We report the selective erasure of a previously recorded 100% diffraction efficiency grating in a photorefractive lithium niobate crystal. Both the recording and the selective erasure are carried out using self-stabilized holographic recording techniques. The recording and the erasure are shown to be in excellent agreement with the proposed corresponding theoretical model. After erasure, a grating of less than 5% diffraction efficiency remains in place. Almost no sensible light scattering was detected.

Sampled dynamic holographic memory.
We report the experimental demonstration of a photorefractive dynamic holographic memory that has a simple feedback architecture stabilized through a novel spatial sampling technique. By using dynamic copying to compensate for photorefractive decay, this memory provides nondestructive readout, selective erasure and rewriting, and real-time adaptation of holograms through an arbitrarily large nu...
متن کاملStabilized photorefractive running holograms, with arbitrarily selected phase shift, for material characterization
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 along the same direction behind the photorefractive crystal. The dependence of the diffraction efficiency and of the hologram speed on φ , in such stabilized holograms, can be easily measured and used for material...
متن کاملLocalized holographic recording in doubly doped lithium niobate.
Persistent holograms are recorded locally with red light in a LiNbO>(3) crystal doped with Mg and Fe. Selective erasure is realized by use of a focused UV sensitizing light. We demonstrate the recording of 50 localized images as well as selective erasure in a 4 mm x 4 mm x 4 mm crystal. A comparison of the total recording time for M holograms obtained with the conventional distributed-volume re...

Due to very interesting properties like reversible recording with unlimited number of recording-erasure cycles, high image resolution and high storage capability, thick photorefractive media have been applied in many areas like information storage (Chuang & Psaltis, 1997), pattern recognition (Alam & Khoury, 2000), phase conjugation (Chang et al, 2001), optical image processing (Poon & Banerjee...
