METHOD FOR NIGHT AND/OR DAY OBSERVATION OF A REMOTE OBJECT WITH SYNCHRONOUS PHASE MANIPULATION BY LASER ILLUMINATION PULSES AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2006 - IPC G02B23/12 G01S17/88 

FIELD: laser-based locating systems.

SUBSTANCE: first pulse T^t _le ≤ 100ns is sent to object and on basis of reflected light emission time T is determined need for expansion of emission to object. (m-1) pulses are formed with length Tⁱ _le and by means of receiving objective and matrix of photo-sensitive devices with charging connection, image of object is received. Beginning of each one of (m-1) laser pulses is shifted from the beginning of frame of matrix of photo-sensitive devices with charging connection for time T_ctrl.le, and beginning of each period of accumulation of matrix of photo-sensitive devices with charging connection is shifted from the beginning of frame for time T_ctrl.b. Device has pulse laser in transmitting channel, block for powering and controlling the laser and optical system, in the first optical channel - first receiving objective, matrix of photo-sensitive devices with charging connection and display, in second one - second receipt objective and photo-diode, and also control block for controlling length of pulses, displacement of beginning of pulses and beginning of accumulation period for matrix of photo-sensitive devices with charging connection.

EFFECT: improved quality of image both during nighttime and daytime, and also increased resistance to interference due to use of synchronous phase manipulation by laser illumination pulses.
