Abstract
A new methodology for mapping thermal diffusivity using a photothermal deflection method is introduced. Two case studies are made: fiber-rei nforced composite structures and contact damage zones in alumina. In t he former, characterization of thermal microstructural features is dem onstrated; in the latter, microcrack density is quantified. Experiment al data are analyzed and compared with literature results. Advantages and limitations of the technique are discussed.
