The aging of the commercial transport fleet increases the possibility of a reduction or loss of structural integrity through corrosion. Thermal imaging is a nondestructive evaluation (NDE) technique that is non-contacting and can rapidly inspect large areas. In this work, thermal NDE is used for characterization of corrosion in aircraft skin. Thermal images from an infrared camera are low in contrast and raw images give only qualitative results. The technique presented will use the time evolution of the thermal images to produce qualitative and quantitative information of the corrosion sample being imaged. This paper is going to show the results from fabricated material loss samples, electro chemical corroded samples and aircraft panels with corrosion. A quantitative comparison of results for the different samples will be shown.
