A fundamental method and apparatus for using wave-type energy, such as light, to provide: amplification, energy control, and logic functions including OR, EXCLUSIVE OR, and INVERTER; as well as bistable information storage, computing, visual display, and dynamic imaging (where images are modified continually as computation proceeds) is disclosed. The method uses modulated input beams (19, 20) that are able to produce interference fringes, that are separated into constructive interference component regions (22) and destructive interference component regions (21), to provide outputs (23) from individual functions, that result from the interference which occurs in the separated interference-fringe component regions. Many basic functions are interconnected to produce more complex functions including complete digital and analog computers. Holograms made up of many subholograms are used to separate fringe component regions, and to direct function interconnecting beams. |
