Abstract
Optical computing cells or logic cells are constructed of two or more spatial light rebroadcasters (SLR's). Data or information images in the form of light are written into and read from the SLR's with the SLR's being controlled to process the data in a desired manner. The logic cells can be used generally to construct optical computers and are particularly adapted to the construction of optical subsystems for a digital optical computer. In addition, the logic cells can be used for performing masking, interface, intermediate storage and other operations within an optical computer. Cells made up of only SLR's can be used directly for many applications. The cells also can be modified by the internal or external addition of other optical elements for routing light between or among SLR's of the cells, processing and/or blocking light as the light passes between SLR's of the cells. Such modifications and adaptations complement cells made up only of SLR's to form a family of optical logic cells.
