The aim of this project is to investigate a digital optical computer based on distributed modular architecture. Follwing results are obtained in this project :1. As a prototype of high performance optical computing system, a module-integrated architecture is proposed. The architecture is composed of several types of functional modules. We have clarified problems in sysytem develop and have considered several implementations of the modules for processing and interconnection.2. A discrete correlator, the most important module in the module-integrated architecture, is developed with planer micro-lens arrays. On the developed correlator, fundamental operations are executed to verify the principle. Processing capability of the correlator is estimated.3. As a technique for packaging of middle-size optical systems, reflective block optics (REBOP) is developed. The REBOP is based on cubic glass blocks attached with reflective optical elements. Applications of the REBOP are presented for micro/macro hybrid optical interconnection and digital optical computing system. Processing capability and performance estimated.
