Abstract
Laser thermography is a sub-domain method in active thermography that uses a laser as the heat source. The method allows for precise control of the beam shape, pulse duration, and delivered energy. Therefore, this technique can be applied especially for delicate structures where testing conditions must be maintained precisely. The following work includes the introduction of a laser spot thermography technology demonstrator that was designed and constructed at AGH UST. The paper presents laser thermography laboratory experiments along with the developed procedure for automatic defect identification. The measurements were used to establish an automatic procedure and algorithm for automatic defect identification based on regression methods and a K-means clustering algorithm. The procedure leads to the indication of faulty and flawless regions of the sample. Experiments were conducted on a carbon fiber reinforced polymer (CFRP) sample with artificially created defects in the form of Teflon inserts imitating delaminations on various depths.
