An approach is proposed which combines simultaneously advantages both of pulse (PT) and modulated infrared thermography. In a nondestructive evaluation perspective, the specimen heated as in PT mix frequencies thermal waves launched into unscrambled by performing Fourier transform temperature evolution over field view. Of interest maximum phase image with many attractive features: deeper probing, less influence surface optical characteristics, rapid recording (pulse heating, surface-wide...
Abstract In this article, the theoretical and experimental aspects of three active thermography approaches: pulsed (PT), lock-in (LT), vibrothermography (VT), are discussed in relation to nondestructive evaluation (NDE) honeycomb sandwich structures. For purpose, two standard specimens with simulated defects (delaminations, core unbonds, excessive adhesive, crushed core) were tested, results processed, examined, compared. As will be pointed out, similarities differences between these...
Pulsed Phase Thermography has considerably evolved since it was originally introduced in 1996. In this paper, a general review of the technique is presented. The different types uncertainties related to data acquisition and processing are identified. Equivalence between discrete continuous Fourier Transforms when applied thermographic discussed detail. As will be pointed out, optimal solution for problem, qualitative or quantitative, arises from compromise sampling rate, truncation window...
Thermography is a nondestructive testing (NDT) technique based on the principle that two dissimilar materials, i.e., possessing different thermo-physical properties, would produce distinctive thermal signatures can be revealed by an infrared sensor, such as camera. The fields of NDT applications are expanding from classical building or electronic components monitoring to more recent ones inspection artworks composite materials. Furthermore, thermography conveniently used didactic tool for...
In this paper, optical and mechanical excitation thermography was used to investigate basalt-fiber-reinforced polymer, carbon-fiber-reinforced basalt-carbon fiber hybrid specimens subjected impact loading. Interestingly, two different structures including sandwich-like intercalated stacking sequence were used. Pulsed phase thermography, principal component partial least-squares (PLST) process the thermographic data. X-ray computed tomography for validation. addition, signal-to-noise ratio...
Abstract Infrared thermography has been widely applied in real industrial inspections of aerospace, energy management systems, engines and electric systems. However, the two-dimensional imaging character this modality limits its development. Here, a technique named frequency multiplexed photothermal correlation tomography (FM-PCT) was developed to enable non-destructive contactless cross-sectional for manufactured material evaluation characterization. By combining advantages pulsed...
