DEVICE FOR DEFINITION OF ANGLE COORDINATES OF PULSED LASER RADIATION SOURCE Russian patent published in 2009 - IPC G01S17/06 

FIELD: physics, optics.

SUBSTANCE: invention is related to instruments for determination of angle coordinates of pulsed laser radiation sources and may be used in protection of different objects against directed aiming. Device comprises control unit, photodetector on the basis of photodiode, two superwide-angle lenses, in focal plane of which two light-sensitive matrices are installed accordingly; time for accumulation of signal of every light-sensitive matrices, on the one hand, is so insignificant, that it provides for absence of day background, and on the other hand, it exceeds time for reset of accumulated signal by second matrix, which provides for continuity of space viewing; control unit connected to the first and second light-sensitive matrices and with photodetector device, provides for alternate accumulation of signal by light-sensitive matrices and determines angle coordinates of pulsed laser radiation source and time of signals appearance at the outlet of photodetector; light-sensitive matrix in mode of signal accumulation at the moment of signal appearance at photodiode outlet, on completion of accumulation mode transferring into mode of signal reading by control unit; at that analysis of time-pulse modulation of signal at the outlet of photodetector may be used for recognition of friend or foe.

EFFECT: increased distance of laser radiation source and space viewing angle detection, increased accuracy of laser radiation source angular position measurement, and possibility to control surrounding space in continuous mode, which increases possibility of aiming device detection and destruction of enemy adjusting their sights.
