title = "A fast and robust method for determining thermal diffusivity images in complex geometries",
abstract = "Active thermography is a widely used method in the field of non-destructive testing (NDT) for the analysis of materials and structures with which it is possible to determine material properties as well as to detect and characterize flaws. Applying pulsed thermography (PT) to various materials with different sample geometries, it has been possible to show that thermal diffusivity can be calculated from recorded thermal time series by applying a fast and robust curve fitting method. This reference-free evaluation is based on the determination of physical properties derived from the ID-heat diffusion equation. In this paper, results from thermal diffusivity measurements carried out on carbon fiber reinforced plastics (CFRP) and glass fiber reinforced plastics (GFRP) are showing that the application of a 'shape correction' method allows improved diffusivity images of complex geometries to be generated.",
