Paper Abstract

After a rapid introduction that indicates the main reasons for the renewal of interest for photorefractive holographic memories, we will first present and compare both the coding techniques and recording procedures used for storage of superimposed images. Potentialities and limitations that are relevant to existing photorefractive crystals will be then discussed. Refreshing procedures that allow to operate the dynamic memory without loss of information will be also described. We will then devote the major part of the article to discussing applications we envision for photorefractive holographic memories.
