Optimization of the pulse-compression technique applied to the infrared thermography nondestructive evaluation

NDT & E International, 2017
Abstract Pulse-compression infrared thermography is an emerging nondestructive testing and evaluation technique. An analysis of the main issues hampering the full exploitation of this technique is presented from both theoretical and experimental point of view and various strategies are introduced to overcome these problems and optimize the defect ...

A physics-informed framework for feature extraction and defect segmentation in pulsed infrared thermography

Engineering Failure Analysis
This paper presents a robust and interpretable methodology for defect detection in active infrared thermography data applied to polyvinyl chloride (PVC) specimens. Our approach integrates a physics-based cooling model to describe the transient thermal response of each pixel, from which five primary temporal features are extracted via least-squares ...
