METHOD OF LASER PROBING OF REMOTE OBJECT Russian patent published in 2009 - IPC G01C3/08 G01S17/02 

FIELD: physics, measurement.

SUBSTANCE: method of remote object laser probing that includes sending of laser pulse to object with the help of laser in mode of modulated quality factor, registration of sending moment T1, reception of radiation reflected by remote object, registration of reception moment T2 and determination of time interval T=T2-T1, which is used to identify remoteness of object, which differs by the fact that after moment T2 the second laser pulse is sent to object, moment of its sending T3 is registered, time interval T'=T-ΔT is formed and, starting from the moment of time T4=T3+T', form of received signal is registered for the time t_s=2r/c+ΔT, where r is maximum possible length of object along probing route; c is light velocity; ΔT=2Δr/c; Δr is length of route section in front of object that is subject to analysis.

EFFECT: provision of simultaneous, maximum accurate definition of spatial structure of probed object and distance to it at minimum volume of equipment.
