Active Infrared Thermography is a technique widely used in assessing the conditions of parts of industrial components. The aim of this paper is that of comparing the pulse, the periodically modulated and the chirp methods of heating. The methods will be applied on a CFRP slab, prepared with teflon inserts of various dimensions and located at different depths, to simulate the presence of defects inside the material. The thermographic images of the experiments will be treated to produce eventually a binary map of the location of the defects.

Abstract
Active Infrared Thermography is a technique widely used in assessing the conditions of parts of industrial components. The aim of this paper is that of comparing the pulse, the periodically modulated and the chirp methods of heating. The methods will be applied on a CFRP slab, prepared with teflon inserts of various dimensions and located at different depths, to simulate the presence of defects inside the material. The thermographic images of the experiments will be treated to produce eventually a binary map of the location of the defects.File in questo prodotto:
