FIELD: measurement equipment.
SUBSTANCE: device comprises a laser radiator, a laser radiation phase randomizer, a transceiving optical tract, mirrors that forward radiation collected with a telescope to a photodetector module, and a light filter that reduces photodetector exposure due to a narrow band, and a pilot laser. The transmitting part of the tract comprises a system of guide mirrors, and the receiving part - from the receiving telescope. At the same time the transmitting channel generates directed radiation with time-space and spectral characteristics, which exclude impact of a speckle structure at results of lidar measurements.
EFFECT: elimination of error due to use of a system of randomization of a laser radiation phase for speckle-picture correction, which provides for higher accuracy of measurements.
