    摘要: The purpose of the present invention is to provide a sunshine recorder that has no movable component and permits easy adjustment for measurement. A sunshine recorder (10) has: a lens (101) that emits, as projection light, natural light incident from half of the celestial sphere; a sensor (102) that photoelectrically converts the projection light projected onto a light receiving surface, and outputs the photoelectrically converted projection light; and a determination circuit (104) that determines the presence or absence of sunshine on the basis of an output of the sensor (102), wherein the sensor (102) has a plurality of detection areas on the light receiving surface and is configured to output a signal corresponding to the intensity of the projection light incident on each of the detection areas, and the determination circuit (104) removes a scattered light component included in the projection light on the basis of a difference operation of the signal output from each of the detection areas to extract only a direct light component to be included in the projection light at the time of incidence of sunlight, thereby determining the presence or absence of sunshine in the natural light.

    摘要: 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.
