METHOD FOR ONE-POSITIONAL MEASUREMENT OF LASER EMISSION SOURCE COORDINATES AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2006 - IPC G01S17/06 

FIELD: quantum electronics, possible use for engineering of precision systems, systems for precise targeting of narrow laser rays, trajectory measurements, counting and displaying information, and also for engineering of systems for precise determination of direction to sources of optical emission of space-based equipment, in particular, for tuning of antennas of large radio-telescopes and for communications engineering.

SUBSTANCE: in known method for one-positional measurement of angular coordinates of laser emission source, based on use of scanning optical systems and determination of angular coordinate of laser emission source on basis of angular position of scanning system at the moment when maximum value of useful signal is achieved, scanning of vicinity in selected observation sector is performed due to alternation of heterodyne signal phase front position, and angular coordinate of laser emission source is determined on basis of its angular position at the moment when maximum value of useful signal is achieved. Device for realization of method consists of photo-detector mounted on rotary platform with forming optics and of semi-transparent, held, mounted at an angle of 45° to optical axis, plate, block for processing signal at output of photo-detector, heterodyne, and also of serially connected block for forming parameters of phase front of heterodyne signal and block for controlling phase front of heterodyne signal, while second output of block for forming parameters of phase front of heterodyne signal is connected to second output of signal processing block, second input of block for controlling phase front of heterodyne is connected to output of heterodyne, and output - to second input of photo-detector.

EFFECT: decreased space observation time and increased precision of measurements of laser emission source coordinates.
