摘要:Thermal wave imaging makes use of thermal response over the stimulated surface for detection of anomalies underneath the surface of the test object which requires the deployment of various post processing approaches to extract fine subsurface details. These subsurface details appear at various moments depending on their depth and size. Extraction of these fair details with low axial and temporal resolutions provided by thermal imagers against various noises is a criterion of importance in thermal wave imaging. Capability of non stationary thermal wave imaging to explore the subsurface details within a single experimentation at low powers resulting in gaining the interest in using it motivated the recent research to incorporate various new processing modalities intended to extract fine details along with this stimulation mechanism. This paper highlights the application of various post processing modalities to extract subsurface details using experimentation carried over a glass fiber reinforced plastic specimen with embedded Teflon inserts to simulate de-lamination like defects encountered with composites.
