Damages are inevitable in structures and effective damage detection techniques are
important for maintaining their health. Many weight-sensitive engineering applications use …

Infrared thermography uses the temperature-imaging capability of modern thermal cameras
to characterize materials and detect flaws. An energy source—whether a pulse of light from …

Delaminations are buried defects parallel to the sample surface. In the last decades infrared
thermography with optical excitation has been used to detect and size the depth of this kind …

The key idea in this paper is to propose multi-labels classification algorithms to handle
benchmark thermal datasets that are practically associated with different data characteristics …

Delaminations are flat subsurface flaws parallel to the sample surface. Lock-in infrared
thermography with optical stimulation is proposed to size the geometrical parameters of a …

The efficiency of eight algorithms of defect depth characterization (pulse phase
thermography–PPT, thermographic signal reconstruction by analyzing the first and second …

Pulsed phase thermography (PPT) was proposed in 1996 to enhance results from pulsed
thermography experiments. PPT can be thought as the link between pulsed thermography …

In this paper, we review some of the discrete signal transforms that are in use in the field of
thermography for defect detection and/or characterization. Signal transformation is used with …

In this work, a methodology for fast and accurate estimation of the geometrical parameters of
buried flat flaws by means of lock-in thermography is proposed. With this goal, first, a …

In this paper, an introduction to pulsed thermography and the basic thermal processing is
first presented followed by a detailed review of some of the discrete signal transforms that …
