Active Thermography in Non-destructive Testing
Energy excitation of a test object generates a heat flow that leads to temperature changes on its surface, which can be detected with highly sensitive infrared cameras. Based on the temporal course of these temperature changes, conclusions can be drawn about the material properties and condition of the test object. Active thermography, in combination with high-resolution camera technology and suitable analysis algorithms, allows the detection of even the smallest defects.
During this process, the test object remains intact and can be used for further tests or improved if necessary. Active thermography is a very efficient non-destructive testing method that allows rapid analysis of even large-area test objects made of a wide variety of materials.
