Abstract

Two electro-optical computer interface embodiments provide for one-way read only and two-way optical read and write. The two-way embodiment includes a main module having a shared memory, and a processor/controller and a main bus. A plurality of local processor modules each includes a local memory, a local processor, and a local bus. The processors are electrically joined by control conductors which provide for coordination and timing between local processors and the main processor. Each memory array has a film deposited on it by the Langmuir/Blodgett technique. The memory arrays are each illuminated by a pulsed laser or Q-switched laser. The film is responsive to the electric fields in the memory array cells for modulating the illumination light. The image is then read onto other memory arrays which are responsive to the illumination for transferring the data between memories.
