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 ...

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.

Double active transient thermography
NDT & 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 ...

Pre-detection of microplastics using active thermography
Chemosphere, 2021 Spectrometric analysis is one of the most widely used approaches to characterize the chemical nature of microplastics. Despite recent developments, this key step remains time consuming. The aim of this paper is to propose a new method for the pre-detection of microplastics based on mid-infrared imaging.
