Nonvolatile storage in photorefractive crystals

Not Accessible

Your library or personal account may give you access

Abstract

We propose and demonstrate a nonvolatile holographic recording system for storing two-dimensional images. The readout light in this system is not absorbed by the holographic medium, and the data are preformatted or postformatted so that lines from different holograms are interleaved to satisfy the Bragg-matching condition.
