摘要：

A non-destructive remote sensing technique for obtaining quantitative thermal diffusivity depth profiles of near-surface inhomogeneities in opaque solids is reponed. In this technique, the difference in the photothermal signal frequency response of a sample with an inhomogeneous surface layer compared with that of a homogeneous sample of the same material has been utilized. The signal was monitored by the radiometric emission from the sample surface. Applications to the inspection of laser-processed Zr-2.5Nb alloy samples are presented. Profiles obtained from this method are consistent with the profiles obtained from destructive methods such as microhardness testing.
