ABSTRACT
Active Thermography (AT) is a package of methods who use thermal cameras to make visible internal defects, surface cracks and material stress. Currently, they are several techniques based on active thermography: lock-in, pulse, transient, vibro and thermal stress analysis. Depending on the inspection task, one or more methods are used. This paper will give a brief overview of each method and will introduce several IR cameras suggested to be used in AT systems.
KEYWORDS: active thermography, lock-in, thermal camera, thermovision, thermal stress analysis. *Corresponding authors: Marius Popovici, Tel. 021 314081, 82 Fax 021 3124083, e-mail: This e-mail address is being protected from spambots. You need JavaScript enabled to view it |
