Abstract: 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.

Abstract: A material-like decorating sheet that forms a material pattern on a surface of a decoration target component by being attached to the surface of the decoration target component includes a sheet-shaped transparent base film, and a colored layer disposed on a back surface of the base film and forming the material pattern with one or more inks. The base film has, on an outer surface, an uneven portion that provides a texture corresponding to the material pattern. The colored layer has an uncolored pattern including a plurality of uncolored areas that are portions not colored with the one or more inks.

Abstract: 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.

Abstract: A first operation region 11 for providing a first tactile sensation and second operation regions 12_U and 12_D for providing a second tactile sensation are arranged adjacent to each other. when a detection unit 20 detects a slide operation from the first operation region 11 to the second operation region 12U or 12D, an operation control unit 30 outputs a second operation signal different from a first operation signal output depending on a movement distance of the slide operation on the first operation region 11. Therefore, the second operation signal is output when the degree of operation is not sufficient even by performing a slide operation within the first operation region 11, and the movement of the finger stops at a place where a change from the first tactile sensation to the second tactile sensation occurs. As a result, it is possible to allow a user to perform an operation of a degree of operation desired by the user without performing the slide operation several times.
