Description
Among all the photothermal techniques that have appeared since some years, the photothermal radiometry is very attractive because of its noncontact and rapid-scanning ability [1,2]. In our laboratory, we developed pulsed stimulated infrared (IR) thermography [3]. Due to the relatively low refreshment frequency of the currently used IR cameras, the application of the method was restricted to low thermal conductors. In particular, we applied it to carbon/epoxy composites [4,5]. Some new developments of the data reduction procedure were presented last year [6] to use this technique with good heat conductors. Satisfactory results were obtained in the case of delaminations in C/C composites. We present here an improvement of this data reduction procedure which is able now to work with any kind of material. We will focus our attention on the especially difficult case of the characterization of adhesive joints in metallic structures.
