| Research Abstract |
A noninvasive technique was developed to measure the thermal conductivity and the thermal diffusivity of biological and soft materials. This technique involves laser heating and infrared thermometry of target surface. The thermal transport properties are determined by comparing measured temperatures with those calculated analytically using an appropriate model. But the temperature profile of the calculation was different from the experimental result of agar gel. To identify the cause of the difference, the radiative influence from inside of the gel, evaporation of the surface and others were examined. As the result, it was proved that the temperature difference was almost caused by the spreading of light between the photodetectors of our infrared thermometer.
