FIELD: communication equipment.
SUBSTANCE: invention relates to electrical communication, particularly, to control of laser light beams, and can be used in systems of quantum cryptography through free space and for communication between several aircrafts (AC) and / or aircraft and ground stations. In system for simultaneous control of several laser beams by means of fixed liquid crystal matrix containing liquid crystal matrix SLM, lasers, photodiodes, angle reflectors, fiber-optic cables, fasteners, and also comprises two transceiving units, optically interconnected, each of the above units comprises an inclined turning mechanical platform made with possibility of mutual orientation of the above units to each other, at that, on each of said inclined-turning platforms there arranged are said liquid crystal matrix (SLM) with photodiodes fixed on it, corner reflector, transceiving device connected by means of fiber-optic cables with at least two collimators, as well as a computer; liquid crystal matrix (SLM) surface is divided into at least two regions allocated for receiving and transmitting channels, wherein liquid crystal array SLM is configured to simultaneously focus and / or change direction in real time of at least two laser beams generated by laser of receiving / transmitting device, and independent simultaneous monitoring of said areas of SLM surfaces by changing voltage supplied thereto, controlled by control unit.
EFFECT: technical result consists in creating a system which enables simultaneous control of several laser beams using SLM without loss of time for switching between channels and correction of aberrations simultaneously in all channels with achieving a technical result, which consists in reducing the time of transmitting information.
