Abstract

New optical discrete correlators based on multiple-imaging systems with a simple structure and good stability are proposed. The systems are composed of lenses for image duplication and optical shutters for kernel specification. As a result, large throughput can be attained with an incoherent configuration. The throughput of the system is estimated, and several logic operations are demonstrated to verify the usefulness of the proposed systems for digital optical computing. The proposed system will be especially useful for constructing a compact and stable optical computing system.
