FIELD: optics.
SUBSTANCE: invention relates to optical probing of atmosphere. Combined lidar comprises a laser for generating light pulses, a lens collimator for forming a narrow probing beam, antenna switch from thin-film polariser and quarter-wave plate for accurate alignment of optical axes of transmitting and receiving channels, transceiving afocal mirror telescope, double aperture diaphragm, visual angle detector of receivers, an interference light filter and two photodetectors, a recording system and a computer. In lidar there is a pair of moved diaphragms, one of which is located in transmitter, and another - in receiver, which allows device to operate in two modes - Aerosol Lidar mode and Turbulent Lidar mode.
EFFECT: technical result consists in creation of structure, capable of stable operation in modes of remote probing of atmospheric aerosol and atmospheric turbulence.
