Optical memory disks in optical information processing
Abstract:
We describe the use of optical memory disks as elements in optical information processing architectures. The optical disk is an optical memory device with a storage capacity approaching 10(10) bits which is naturally suited to parallel access. We discuss optical disk characteristics which are important in optical computing systems such as contrast, diffraction efficiency, and phase uniformity. We describe techniques for holographic storage on optical disks and present reconstructions of several types of computer-generated holograms. Various optical information processing architectures are described for applications such as database retrieval, neural network implementation, and image correlation. Selected systems are experimentally demonstrated.
