Paper Abstract
In this work, we investigated a Hyperspectral NDE (HySpecNDE) technique for detection of early damage and material degradation in metallic structures and components. A hyperspectral imaging camera in middle wavelength infrared (MWIR) was used to examine metallic specimens with damage and material degradation created from tensile testing. Hyperspectral data in the MWIR range at ambient and elevated temperatures was acquired and analyzed with a set of data analysis and image processing algorithms. By comparing the digital image correlation results during tensile testing and the hyperspectral analysis results, we demonstrated that HySpecNDE technique unveils the variations in emission intensity, which correspond to early damage and material degradation in materials.
