Abstract
This paper presents the theoretical and experimental possibilities of a modulated photothermal method, laser-induced photoreflectance, for i nspecting the quality of interfaces with micronic spatial resolutions. An analytical model is established for semi-infinite materials contai ning an internal interface perpendicular to the sample surface. Applic ations are the detection of thermal resistances in damaged materials a nd at interfaces between reinforcements and matrix in composites.
