Three-Dimensional Non-Destructive Inspection Using Novel Infrared-Terahertz Fusion Approaches

The imaging of structures with a complex material composition and geometry is still challenge in the field non-destructive testing (NDT). In this study, non-invasive technique proposed for inspection both cultural heritage natural fiber composites. combines surface information provided by infrared thermography (IRT) internal structure retrieved terahertz (THz) time-domain spectroscopy using an unsupervised deep residual fusion network. Experiments show that results contain more than single modality. addition, 3D has been achieved on
