<p>The method is for the non-destructive testing of multi-layered structures for irregularities, whereby the structure (1) is radiated by a heat source (2) with variable intensity. The heat radiation emanating from the heated structure is recorder by an infrared camera (3). The heat source and the infrared camera are located on the same side of the multi-layered structure. A multi-layered structure of layers glued together can be tested or a structure of metal sheets lying one upon the other can be tested.</p> |
