PROBLEM TO BE SOLVED: To provide a temperature calibration method for infrared detectors, and a method for measuring a specific heat capacity by using a temperature-calibrated infrared detector, without using a thermocouple.;SOLUTION: One surface of a standard sample is irradiated with laser pulse light, and a temperature change of the other surface is measured with a thermocouple for a predetermined period of time, and simultaneously an output change corresponding to the temperature change of the sample is measured with the infrared detector; exponential attenuation regions of these temperature and output changes are determined; and from a measured temperature with the thermocouple corresponding to a measured output with the infrared detector at a predetermined point of time in these regions, a temperature conversion coefficient for the measured output with the infrared detector is found. After the incident energy of the laser pulse light to the standard sample is found, one surface of a measuring sample is irradiated with laser pulse light; a temperature change of the other surface is measured with the temperature-calibrated infrared detector for the predetermined period of time; from the temperature change a maximum temperature rise value of the measuring sample on the occasion of the irradiation of the laser pulse light is found; and the specific heat capacity of the measuring sample is found from the incident energy and the weight of the measuring sample.;COPYRIGHT: (C)2009,JPO&INPIT
