Flash-pulse thermography is a method for the detection of discontinuities or inhomogeneities in materials at their surface. It is based on excitation of inspected samples by a short pulse and analysis of its thermal response. It is basically an indicative method, however, quantitative&#...

Formation of Laser Induced Periodic Surface Structures (LIPSS) is a very interesting phenomenon. As the process is now moving towards the industry for the production of functional surfaces, a monitoring technique for online process control is needed. In the present work, the process...

Surface functionalization as well as the microstructure modification of electrodes by laser material processing has become increasingly important in recent years. Short and ultra-short pulsed lasers, which enable high-precision processing, are us...

Infrared nondestructive testing (IRNDT) is an active thermography method for inspection of material-surface inhomogeneities or discontinuities. It is based on an excitation of an inspected sample and a detection of its thermal response by thermographic methods. The IRNDT is commonly used for...

Active thermography and its approaches are introduced in this contribution. Possibilities of active thermography are demonstrated on two examples – inspection of steel walls and inspection of components at cyclic loading. Example of an inspection of a corrosion loss at rear ...
