Abstract
The present invention provides a method for measuring thermophysical properties that includes: rapid resistive self-heating of a specimen by using a heating current; emitting a light to the specimen heated by the rapid resistive self-heating of the specimen; measuring a temperature change of the specimen induced by emitting the light to the specimen; and deriving a thermal diffusivity of the specimen from the temperature change induced by emitting the light to the specimen.
