FIELD: meteorology.
SUBSTANCE: group of inventions relates to lidar means for monitoring the content of ice crystals in the atmosphere. The lidar system includes laser (1), collimating lens (2), thin-film polarizer (4), quarter-wave plate (5), two mirrors (6, 7) forming a two-mirror afocal telescope, glass plate (10), interference filter (14), focusing lens (15), aperture diaphragm (16), rotating mirror (17), two detectors (18, 19), registration unit (20), and data processing unit (21). In this case, one half of glass plate (10) is plane-parallel, and the other half has a wedge shape.
EFFECT: improved accuracy of monitoring the content of ice crystals in the atmosphere.
