ABSTRACT:
An optical cross bar technique for logic and arithmetic operations utilizes crossed optical paths of light configured to define intersecting regions with each other corresponding to truth table or multi-level logic table inputs. The intensity of light at each intersecting region is discriminated to determine if two units of light intensity are present at each intersection, thereby indicating a particular logic state.
