Abstract
This contribution demonstrates an application of non-stationary frequency modulated thermal wave imaging technique for the numerical characterization of a mild steel sample containing random shape defects. Frequency and time domain based phase analysis schemes are implemented on the recorded thermal profiles and their detectabilities are compared by taking signal to noise ratio into consideration.
