We describe an optical image processing system with regenerative feedback that utilizes a cavity with a phase-conjugate mirror. The system’s characteristics and limitations are discussed, and its application to the implementation of iterative recovery algorithms (e.g., Gerchberg algorithm) is considered and demonstrated experimentally.
