An optical receiver for a meteorological lidar capable of accurate measurement of scattered light generated by emitting a laser beam of the UVC range (wavelength of 200 to 280 nm) into the air, without using a diffraction grating, is provided. The optical receiver for a meteorological lidar that emits a laser beam of a specific wavelength in the UVC range into the air and measures scattered light generated by the laser beam includes a reflector that reflects incident light to a predetermined direction, and a spectrometer that isolates a specific wavelength from incident light from the reflector, wherein the spectrometer includes interference filters.

Optical receiver for meteorological lidar

A meteorological lidar capable of measuring vertical distributions of temperature, water vapor concentration, aerosol, wind direction/wind speed, ozone concentration, COconcentration, etc., stably and continuously day and night is provided. A meteorological lidar that emits a laser beam of a specific wavelength into the air and measures scattered light generated by the laser beam includes an optical system that emits a laser beam into the air, and a dust-proof part that makes an enclosing space of the optical system clean.

Meteorological lidar

A meteorological lidar performs highly precise meteorological observation by primarily removing elastically scattered light and by detecting rotational Raman-scattered light without filtering it out. The meteorological lidar according to embodiments measures scattered light of a laser beam, and includes: a diffraction grating diffracting rotational Raman-scattered light contained in scattered light in accordance with the wavelength of rotational Raman-scattered light; a detector detecting the diffracted rotational Raman-scattered light; and a removing element primarily removing elastically scattered light of a specific wavelength contained in the scattered light.
