METHOD AND DEVICE FOR MEASURING TEMPERATURE

摘要

PROBLEM TO BE SOLVED: To enable measuring a temperature in a deep part deeper than the body surface of an organism.SOLUTION: A temperature measurement part 101 obtains a measurement result by an OPBS method by irradiating a first light of a wavelength λ1 in an infrared region and a second light of a wavelength λ2 in an infrared region having a different wavelength, to a deep part of an objective depth from the body surface having an unknown parameter comprising a temperature T. The first light and the second light are determined by a relationship between a previously demanded light wavelength in an infrared region, becoming a light absorption coefficient of the same water in an objective depth from the body surface, and a light absorption coefficient of water depending on a depth from the body surface. A temperature derivation part 102 determines a temperature in a set deep part deeper than the body surface from the previously measured concentration C1 of the first component of blood and concentration C2 of the second component of blood, and a measurement result of the temperature measurement part.
