This is mainly a validation by infrared thermography of an experimental contribution for defect detection by contact based on the flash method, generally used to characterize the thermal diffusivity of the material. Indeed, we have conceived and realized a contact thermal sensor consisting of forty-nine type K thermocouples distributed over the rear face of the sample to be tested. The thermocouples...
In this paper, an advanced approach to characterize defects in homogeneous materials based on multiresolution analysis of infrared images is presented. This is mainly a non-destructive evaluation technique based on the flash method in transmission mode. An experimental device using infrared thermography was designed and realized. The equipment includes an infrared imager for following the temporal...
