Thermal-wave diagnostics by means of infrared photothermal radiometry (PTR) has been used for quantitative non-destructive evaluation of cylindrical composite structures. To quantitatively evaluate the thermal-wave field of a cylindrical composite material, the Green function corresponding to the composite structure has been developed and subsequently the thermal-wave field has been derived. Furthermore, the characteristics of the thermal-wave field for a cylindrical material with a surface coating are discussed. Experimental results from a stainless steel (AISI 302) tube are used to validate the theoretical model.
