ARRANGEMENT OF OPTICAL COMMUNICATION LINE Russian patent published in 2002 - IPC

FIELD: optical communication, atmospheric optical communication lines installed on masts or on tall buildings. SUBSTANCE: arrangement of optical communication line has transmitter, three receiving antennas, frame-holder, three photodetectors, unit for commutation and addition of signals, decision-making unit, unit evaluating error between coordinates of energy center distributing optical radiation over reception plane and geometric center of equilateral triangle formed by receiving antennas, unit making data of geometric center of equilateral triangle agree in space with data of energy center distributing optical radiation over reception plane. Divergence of optical radiation of transmitter diminishes by factor of K, where K>1 and receiving antennas are positioned on plane perpendicular to optical axis of transmitter, in vertexes of equilateral triangle. EFFECT: increased energy potential of optical communication line. 1 dwg
