Abstract

We have developed high-speed infrared radiation thermometry techniques to detect temperature change of specimen surfaces in pulsed heating methods or periodic heating methods for measuring thermal diffusivity, thermal conductivity and specific heat capacity of solids. Single- and multi-target radiation thermometers have been constructed with one or five InSb sensing elements cooled by liquid nitrogen, which are operated in dc-mode. Calibrations for the temperature scale of InSb thermometers have been made for the range from o℃ up to 200℃ within the accuracy of 0.2 K. Photovoltaic HgCdTe (MCT) thermometers also have been developed for near or sub-ambient temperature for periodic heating methods. The time response measured is fast enough above 1 MHz.
