Abstract (en)
[origin: WO2009118074A1] The invention relates to a method and an apparatus for detecting density and/or thickness variations in materials transparent or partly transparent to infrared radiation, in which an examination object (1, 10) is arranged between an infrared source (3) and a thermographic camera (2), the examination object (1, 10) being irradiated by the infrared source (3) and the thermographic camera (2) arranged opposite the infrared source (3) detecting and evaluating the infrared beams from the infrared source (3) passing through the examination object (1, 10).
