ABSTRACT:
An optical data switch for use within a multiprocessing environment is disclosed. Each processor has associated with it a data projector, such as a laser or an array of light emitting diodes, and a reading device, such as a Charge Coupled Device array. An optically reflective screen, or mirror, is arranged so that all processors can project their data on the screen at a specified location. Each processor's reading device has a view of the entire screen, thereby being capable of reading data from any other processor.
