title: Optical cellular logic image processor: implementation and programming of a single channel digital optical circuit.
abstract: A diode-laser driven all-optical iterative processor has been constructed and tested. Results are presented showing operation equivalent to a single channel of the cellular logic image processor architecture. Functional features of the circuit include optically programmable logic, thresholding, and data synchronization. Essential elements such as cascadability, logic-level restoration, and data feedback have been demonstrated with the optical processor controlled by a conventional electronic computer. Serial processing algorithms for word recognition, comparison, full addition, and subtraction have been implemented. Comments on the reliability of operation and future plans for expansion are made.
