Barker coded thermal wave imaging for defect detection in carbon fibre-reinforced plastics
Abstract:Active thermal non-destructive testing (TNDT) methods utilise the acquired surface temperature profile over an object and subsequently process the obtained temperature data to detect surface or subsurface features of the object. This process, however, demands novel processing and excitation approaches to enhance the defect detectability with depth analysis. This contribution is intended to exhibit the detection capability of the recently introduced Barker coded excitation for infrared imaging for characterisation of carbon fibre-reinforced plastic material. Experiments have been carried out for the proposed excitation scheme to study its defect detection capabilities.
