Description

Thermal NDE can be effectively applied for detection of the defects having thermal properties different from the surrounding material. Different image processing procedures help to localize amplitude variations produced by the subsurface defects on thermograms received during the cooling stage after a heat excitation of the subject surface. An application of the thermal tomography method for quantitative defect characterization and defect visualization in composites is studied. The emphasis of the study is the automation of processing of the thermal images.
