    Beschreibung

    This paper gives some practical, simulated and calculated design parameters for the detection of voids inside the material with active thermography for different void geometry, orientation and depths. The main goal is to find the limitations of detectivity for different materials and voids, to help designers for test systems with: a quick estimation of the feasibility and to find the necessary camera parameters. The methods used (algebraic, numeric and practical) to find these values will be described. For inline applications the so called square pulse technique is easy to automate and needs less power from the source, because energy can be brought into the probe for a longer time span.
