Paper Abstract

Photothermal thermography is a nondestructive technique for the analysis and testing of materials which associates the excitation of the tested parts by a flash with the detection of the induced temperature increase, thanks to an infrared thermography camera. We present here an apparatus called MECIR, which results from a several year long collaboration between both a research laboratory of the University of Reims and an outstanding civilian and military aircraft constructor. It includes an AGEMA infrared camera, a specially conceived system for the image capture and the treatment of data, as well as an illuminator composed of four Xenon flash tubes. The apparatus is to be used for the rapid testing of rather flat and large parts. We show the results of defect controls in objects made of composite materials and used in the aeronautic industry. (*) The development of MECIR is being sponsored by the French Ministry for Research and Technology.
