  • Abstract
    We propose an all-optical fault-tolerant holographic memory with two photorefractive crystals. The memory system call automatically detect "dropout" data and rewrite a corresponding data from the back up crystal. We analyze the temporal response of the memory, and show how the dropout data are restored automatically.
