Pulse Compression Favourable Thermal Wave Imaging Techniques for Non-destructive Testing and Evaluation of Solids
Non-Destructive Testing and Evaluation (NDT&E) is essential for inspecting materials without compromising their serviceability. Among the wide range of NDT&E methods, Infrared Thermography (IRT) has gained prominence for its non-contact operation and rapid inspection capabilities. Passive thermography, though simple and fast, is limited in detecting small, deep sub-surface features. To address this challenge, active thermography applies a controlled thermal stimulus to probe sub-surface anomalies quantitatively. However, conventional pulse-based and lock-in methods still face limitations such as shallow penetration, high power demands, and repetitive testing requirements.
In this webinar, Prof. Dr. Ravibabu Mulaveesala will introduce innovative insights into Frequency Modulated Thermal Wave Imaging (FMTWI) and its integration with correlation-based post-processing for enhanced sub-surface defect detection and interface bond quality evaluation in metals and sandwich structures. The presentation will explore how thermal responses, captured using infrared thermography, are analysed through frequency-domain, time-domain, and Cross-Correlation Coefficient (CCC) methods—where CCC quantifies the similarity between thermal responses to enhance defect detection.
This session will highlight the significance of combining FMTWI with CCC post-processing to achieve superior sensitivity in identifying delamination and sub-surface anomalies.
