Induction thermography

With induction thermography, eddy currents are induced in the component at a particularly high frequency (in the MHz range). Infrared images can be recorded in parallel and subsequently. Due to the high-frequency excitation, the method is suitable for measuring dynamic temperature fields, for fast and extensive defect testing and for characterizing materials in thin layer and edge zone areas. A differentiated view of different material groups is possible by using spectral band filters.
