Abstract

Preliminary results on inversion of thermal wave images were presented at Thermosense XIV. A technique was introduced for removing the blurring of thermal wave images of planar subsurface features such as delaminations. At that time the technique was limited to the case of thermally isotropic materials, and also ignored multiple scattering effects. In this paper we extend the inversion technique to take into account both anisotropy and multiple scattering. An application to an anisotropic composite is presented.
