Patent ID: 8675184

Claim:
A method for Doppler light detection and ranging (LIDAR) measurement of speeds, the method comprising: directing laser pulses at a medium to be measured at a repetition rate of a plurality of laser pulses per measurement; and operating a detector to detect pulses of radiation, which are emitted by the medium as a result of exposure of the medium to the laser pulses, at a detection rate, the operating including controlling the detector to estimate an intensity of the measurement signal from a previous profile of a measurement signal intensity, select a number of the pulses of radiation which are to be integrated by the detector based on the estimate, and integrate the number of the pulses of radiation per measurement; and wherein the repetition rate is at least one order of magnitude greater than the detection rate, and the laser pulses for each measurement are transmitted at a frequency of greater than or equal to 1 kHz.
