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 ...

Rotating parts belong to critical components of power devices. Thermographic diagnostics can predict their faults and prevent major failures. The diagnostics can be mostly performed only during an operation of the devices. A poor accessibility of the parts and their high speed&#x...

Thermography is a modern diagnostics method with a significant potential for utilization in diagnostics, maintenance, monitoring, or non-destructive testing of power industry devices. The main advantages of thermography belong its non-contact and non-destructive basis, the possibility of area&...

Active thermography is a method for nondestructive inspection of materials. This contribution presents quantitative inspection of coating thickness by flash-pulse thermographic inspection and apparent thermal effusivity based evaluation. The apparent thermal effusivity algorithm for evaluation and visualisation ...

Thickness is one of important characteristics of coatings such as thermal barrier coatings, anticorrosion paints and others. The thickness of these coatings and its homogeneity can influence their properties and it is often measured quantity in industrial applications. Commonly used techniques&#x...
