摘要： A respiratory sensor (10) includes: a light wave circuit (K1) including a light projecting unit (112) that emits light toward exhaled air or inhaled air and a light receiving unit (11J) that receives the light emitted by the light projecting unit, and formed on a semiconductor wafer; and a detection unit (11S) that detects a state of the exhaled air or the inhaled air from the light received by the light receiving unit.

摘要： An infrared optical system includes: a spherical lens unit (4) having an image-forming function as a whole and including one or more spherical lenses that form an image of an incident light beam from a subject; an aperture diaphragm unit (3) that limits transmission of the incident light beam through the spherical lens unit; an aberration correcting plate unit (1; 17) that is disposed at a preceding stage of the spherical lens unit, has at least one aspherical surface, and gives an optical path length difference for compensating an aberration to be generated in the spherical lens unit to the incident light beam; and a lens barrel unit (7) holding the spherical lens unit, the aperture diaphragm unit, and the aberration correcting plate unit.

摘要： A temperature measuring device (TMD) includes: a thermal infrared illuminating unit (2) that irradiates with thermal infrared light (IRSK) a target (JB) whose temperature needs to be measured; a thermal infrared illumination image acquiring unit (1) that acquires a thermal infrared illumination image (IRSG) including an image of the target (JB) irradiated with the thermal infrared light (IRSK); a thermal infrared image acquiring unit (1) that acquires a thermal infrared image (IRG) including the image of the target (JB); a visible light image acquiring unit (3) that acquires a visible light image (KG) including the image of the target (JB); a calculating unit (4) that calculates an image expansion amount (ZHR) of the image of the target (JB) based on the image of the target (JB) in the acquired visible light image (KG) and the image of the target (JB) in the acquired IR illumination image (IRSG); an adding unit (4) that adds the calculated image expansion amount (ZHR) in the acquired thermal infrared image (IRG) to luminance of the image of the target (JB); and a measuring unit (5) that measures a temperature of the target (JB) based on the image of the target (JB) to which the image expansion amount (ZHR) has been added.
