Abstract: An imaging device includes a camera, light sources, an optical bandpass filter, and a conversion unit. The camera includes an image sensor including a N-band color filter (where N is a natural number greater than or equal to 3). The M types of light sources (where M is a natural number that satisfies 2≤M≤N) have the emission spectral characteristics of having respective peaks in mutually different wavelength ranges within a visible light range and a near-infrared range. The conversion unit generates image signals of M bands each having spectral sensitivity to the corresponding one of the mutually different wavelength ranges by performing a matrix operation on an N-band imaging signal obtained by the image sensor when an article is photographed with the camera. The light application direction and the emission intensity are individually selected for each of the light sources.

Abstract: A gas concentration measurement device includes a waveguide including an entrance and an exit, a rotating member, first and second band pass filters on the rotating member and on a pair of planes that intersect each other, and a rotational driver. The rotating member is rotated by the rotational driver so that the first and second band pass filters are selectively located at a transmitting position. When a portion of the rotating member, the first band pass filter, or the second band pass filter, the portion having a maximum radius of gyration around a rotating shaft, is defined as a maximum radius portion, and when a rotation locus obtained by imaginarily rotating the maximum radius portion around the rotating shaft in a view along the rotating shaft is defined as a reference circle, the exit is located in the reference circle.
