Excitation Source Optimisation for Active Thermography [PDF]
Proceedings, 2018 In active thermography, the use of an optimised excitation source can simplify the interpretation of measurement results. Our custom designed source, especially designed for dynamic line scanning thermography, minimises the needed excitation power and ...

Spot Weld Inspections Using Active Thermography
Applied Sciences, 2022 Spot welds have a significant part in the creation of automotive vehicles. Since the integrity of, for example, a car, is dependent on the performance of multiple welds, it is important to ensure the quality of each spot weld.

Double active transient thermography
NDT and E International, 2022 This paper presents an innovative variant of the Active Transient Thermography (ATT), designated Double Active Transient Thermography (DATT), where the component inspected is excited by one heat and one cold sources. The goal is to speed up and improve the temperature contrast, namely for polymer matrix composites parts produced by Additive ...

Dynamic Vascular Imaging Using Active Breast Thermography
Sensors, 2023 Mammography is considered the gold standard for breast cancer screening and diagnostic imaging; however, there is an unmet clinical need for complementary methods to detect lesions not characterized by mammography.

ACTIVE DYNAMIC THERMOGRAPHY IN MAMMOGRAPHY
TASK Quarterly, 2004 We discuss limitations of the known methods of IR imaging in diagnostics of breast cancer. In conclusion we show that the known methods, based on simple observation of external temperature distribution, are not fully effective.

Study of multi-long-pulse thermography using high-power fiber lasers
AIP Advances, 2023 Active infrared thermography tests are performed using a high-power continuous fiber laser as the excitation source. Multi-long-pulses (MLPs) are used to detect deep defects in samples with reduced heating.

Active thermography to look beneath the surface of a historic German aircraft
Research and Review Journal of Nondestructive Testing, 2023 Thermography is a well-established non-destructive testing technique in materials research and defect detection. In addition, it is used on cultural heritage in the form of buildings and paintings.
