A new class of optical communication systems. 1: Experiment
Abstract
A new class of optical communication schemes is described in which a message is coded spatially in a random phase process and detected at many points at the receiver. This process may be termed a spatial-multiplex, spatial-diversity optical communication scheme. The technique shows relative immunity to the effects of atmospheric turbulence. Also, relative security of the method is assured since detection can take place only when radiation is detected and processed at many points within the beam itself.
