Thermographic inspection means and non-destructive inspection method for the structure near the surface of a test object

摘要

A thermographic inspection means for non-destructive inspection of a structure near the surface of a test object, a heating device for applying thermal energy to a heated region of the test object, and subsequent application of the heat energy, A thermal sensor means for detecting a temporal profile of a spatial temperature distribution on the surface area to be measured, a heated surface area, and a measured outer surface area adjacent to the heated surface area Evaluation means are provided for evaluating the temporal profile of the spatial temperature distribution so as to detect at least one parameter of the surface area and the near-surface structure in the surface area to be measured.
