OPTICAL COMMUNICATION LINE DEVICE Russian patent published in 2001 - IPC

FIELD: open optical communication lines. SUBSTANCE: device used to eliminate mismatch between optical axis of communication line and optical radiation axis of transmitter has displacement unit, control unit, and array of optical transducers mounted perpendicular to optical axis of communication line. Receiver is placed in center of array and mechanically coupled with displacement unit and with array. Control unit is electrically connected to optical transducers of array and to displacement unit. Divergence of transmitter optical radiation is reduced by K times, where K > 1, which makes it possible to evaluate spatial mismatch between energy centers of transmitter optical radiation beam and center of receiver effective aperture directly in plane of the latter and to compensate for this mismatch by spatial displacement of receiver. Device also provides for raising energy potential of optical line by M < K² times. EFFECT: reduced mismatch of transmitter and enhanced energy potential of optical line. 1 dwg
