Active Thermography as a Process for Non-destructive Testing
The essential feature of active thermography is the targeted supply of energy to the test object. A temporal and spatial characteristic heat flow results depending on the geometry and thermal properties of the test subjects. Its progression on the surface of the test object is captured by a thermographic camera.
The cooled high-end camera series ImageIR® by InfraTec and uncooled microbolometer cameras of the latest generation of the VarioCAM® series by InfraTec are particularly suited for depicting the resulting temperature distributions. The geometric resolution of up to (2,560 × 2,048) IR pixels, high refresh rates as well as exact triggering and thermal sensitivity well below 0.015 K provide the technical requirement for detecting the smallest material defects.
Rely on infrared thermography for non-destructive testing, benefit above all from the variable application of the process for different materials and material combinations. You can detect very different defects. This includes defects in joints, cavities, cracks or faulty joints. Thanks to such qualities, active thermography has firmly established itself as an efficient method for contactless and non-destructive testing in recent years.

Efficient Control and Analysis Software for Active Thermography
The thermography software IRBIS® 3 active analyses the thermo-graphic sequences, which have been generated during the test, and edits them to create a false colour image, in which defects can be marked for further evaluation or documentation. For this purpose, several different analysis procedures are available. The choice of the correct algorithm depends on the material characteristics, geometry and type of defects to be detected.
While the quotient method investigates the heat flow of the test object by reference to the increase and decrease of the surface temperature, the pulse-phase thermography (PPT) relies on the analysis of the temperature profile of different frequencies. For each frequency, two event images are generated, one amplitude- and one phase image. The lock-in thermography (LIT) analyses the sequence of periodic excitation of the test object.
