OPTICAL COMMUNICATION FACILITY Russian patent published in 2001 - IPC

FIELD: optical communication. SUBSTANCE: invention is related to system of open optical communication and can be used for two-way information transmission between objects far one from another without employment of wires or optical fibers even if number of objects participating in information exchange is great. Optical communication facility includes transmitter coming in the form of several radiators placed on curvilinear surface, aids for modulation of radiation and several subscribers' receivers with demodulation aids. Transmitter is equipped with wide-angle lens located between radiators and subscribers' receivers and radiators are positioned in regions optically coupled to subscriber's receiver. Besides that each radiator is mounted for movement over curvilinear surface and along axis of optical beam emitted by it. Receivers optically coupled to subscriber's radiator with reference to wide-angle lens can be placed on curvilinear surface. Receivers can be mounted for movement over curvilinear surface and along axis of received radiation. Lens can turn around unspecified axis together with radiators and receivers. EFFECT: simplified design, improved operation and reduced energy loss. 3 cl, 4 dwg
