摘要： A component concentration measurement device includes a light application unit that applies pulsed beam light of a wavelength that is absorbed by a target substance for measurement to a site of measurement, and a detection unit that detects a photoacoustic signal generated in the site of measurement where the beam light emitted from the light application unit has been applied. The light application unit applies the pulsed beam light with a pulse width at which a photoacoustic wave that occurs at a rising edge of a light pulse and a photoacoustic wave that occurs at a falling edge of the light pulse do not interfere with each other.

摘要： An embodiment is a temperature measurement method. The physical quantities related to a temperature of a living body are measured. A deep part body temperature of the living body is estimated using a coefficient and the measured physical quantities. An index is calculated using the measured physical quantities and the estimated deep part temperature. In a case in which the value of the index exceeds a threshold value, the coefficient is calibrated. It is thus possible to estimate the deep part body temperature more accurately regardless of a change in convection state of ambient air.

摘要： A component concentration measuring apparatus includes: a dielectric spectroscopy portion that irradiates a measurement subject with electromagnetic waves and measures a complex permittivity, thereby acquiring a dielectric spectroscopy spectrum; a temperature measurement portion that measures a temperature of the measurement subject; a signal processing portion that corrects the dielectric spectroscopy spectrum according to the temperature measured by the temperature measurement portion; and a calculating portion that applies a calibration model generated in advance from a dielectric spectroscopy spectrum of a sample whose component concentration is known, to the dielectric spectroscopy spectrum corrected by the signal processing portion, thereby calculating a component concentration of the measurement subject. A dielectric spectroscopy sensor that transmits and receives electromagnetic waves and a temperature sensor that outputs a signal that changes in accordance with a temperature are fixed to the measurement probe such that a certain distance is interposed between the sensors.
