Abstract

Temperature evolution of the irradiated surface of a layered sample was considered. A function is used to determine the moment and time for reading out the information (temperature) from the irradiated surface, when the time variations of the temperature curve slope are dependent on the thermal properties and thickness of the first layer only, thus enabling determination of the thermal properties of this layer and then the same of the second layer. If the thickness and the thermal properties of the layers are known, it is potentially possible to deduce from the temperature evolution the imperfects in the layers.
