A method of measuring the thermal diffusivity of solid material at room temperature with photothermal radiometry is described. By measuring the amplitude and phase frequency characteristics of the photothermal signal, the thermal diffusivity is calculated and compared with the value obtained by the pulsed laser conductometer method.
