Popis:	In this paper we present a new method for calculation of the thermal diffusivity of a rigid body. This method is based on contactless thermal treatment of the examined construction material by an infrared radiation source. Further we analytically find one-dimensional non-stationary temperature field of a rigid body during its heating using data from thermal elements. The calculation of the thermal diffusivity of a rigid body is made using differential heat equation.
