摘要：
A method of measuring the thermal diffusivity of solid material at room temperature with photothermalradiometry 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. © 1990 Optical Society of America.
