“…In the literature, we can find many existing packages of this type that are available for processing thermograms such as the open-source IR View Toolbox [4]., the Altair-Li suite provided by Cedip, RTools by FLIR [ 5,6]., the ThermoFitPro software by Innovation Inc., [7] and Termidge [8].Although several methods have been proposed to investigate defects, flaws, voids etc in materials/systems, none has so far been free from certain disadvantages. The main objective of this GUI is ensure loading thermal images from data base , display them and perform their preprocessing, processing and quantification to characterize the possible subsurface failures inside sample…”

Abstract:The Infrared non-destructive evaluation (IRNDE) is an emerging approach for non-contact inspection of various solid materials such as metals, composites and semiconductors for industrial and research interest. Data processing is an essential step in IRNDE in order to visualize the subsurface defects in the sample and determine the shapes and sizes of the same. The data processing intends to analyse temporal variations in the contrast of each pixel, relative to defect-free reference point on the sample. For that, several post processing algorithms are applied to the recorded thermograms. In this work, it is proposed to an advanced graphical user interface (GUI) for processing the recorded thermograms by IR camera using MATLAB, that supports preprocessing, processing and quantification is presented. Investigations arecarried out using the thermal image sequence recorded with different active thermographic methods: frequency modulated thermal wave imaging (FMTWI) Pulse thermography (PT), lock in thermography (LT). A comparative analysis of the results from different themographic techniques for defect visualization is presented.

“…NDT on composite/metal joints has an inherent difficulty as the response of these complex structures to the excitations used are difficult to be appraised with regard to the component performance in service conditions. However, NDT techniques calibrated against metallographic examinations and mechanical tests can form a basis for reliable NDT test in manufacturing components for critical applications as in the aerospace and nuclear industry [Escourbiac et al, 2007;Ezato et al, 2002;Mergia et al, 2009;. The meatallographic type examinations of the joints as well as mechanical tests are well known and will not be referred here [Kim & Lee, 1998;Park J.-W et al, 2002;Jadoon et al, 2004;Takahashi et al, 2003;Galli et al, 2009;Lee et al, 1995;Serizawa et al, 2006;Serizawa et al, 2007;Serizawa et al, 2008;].…”

IR-View, is a free and open source Matlab software that was released in 1998 at the Computer Vision and Systems Laboratory (CVSL) at Université Laval, Canada, as an answer to many common and recurrent needs in Infrared thermography. IR-View has proven to be a useful tool at CVSL for the past 10 years. The software by itself and/or its concept and functions may be of interest for other laboratories and companies working in research in the IR NDT field. This article describes the functions and processing techniques integrated to IR-View, freely downloadable under the GNU license at http://mivim.gel.ulaval.ca. Demonstration of IR-View functionalities will also be done during the DSS08 SPIE Defense and Security Symposium.
