<P>PROBLEM TO BE SOLVED: To provide a temperature information measurement method capable of easily and speedily measuring temperature information on an analyte by appropriately processing an output value from detection means. <P>SOLUTION: The present invention obtains temperature information on an analyte using the following processes: a wavelength selection process to select two wavelengths λ1 and λ2 which have identical emissivity or known ratio therebetween and have identical permeability from the analyte to an inside of an optical path leading to detection means inside an imaging device or the known ratio therebetween; an input/output characteristic detection process to obtain an input/output characteristic value from a radiant quantity to be input to the detection means as well as an output value from the detection means; a calculation process to calculate offset values Qcλ1 and Qcλ2 respectively for the wavelength λ1 and λ2 from a linear function between the radiant quantity incident on the detection means and the output value when the radiant quantity is zero; a measurement process to obtain the radiant quantities Rλ1 and Rλ2 using the offset values Qcλ1 and Qcλ2 and the linear function; and a temperature information measurement process to obtain temperature information on the analyte using the ratio between the radiant quantities Rλ1 and Rλ2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
