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.

The present invention provides a gene-containing composition including a gene and a transporter, the transporter being capable of transporting the gene from a pregnant body to fetal cells. When this composition is administered to a pregnant body, birth of offsprings with gene deficiency can be prevented, and gene deficiency can be treated during pregnancy. In animal experiments, when an unknown gene is introduced to animals during their embryogenic stage, the function of the gene in ontogenesis can be elucidated. Moreover, the composition can be used for breeding animals such as pets, industrial animals and cattle.
