Masked Sequence Autoencoding for Enhanced Defect Visualization in Active Infrared Thermography
Mohammed Salah, Eman Ouda, Stefano Sfarra +2
Active infrared thermography (AIRT) became a crucial tool in aerospace non-destructive testing (NDT), enabling the detection of hidden defects and anomalies in materials by capturi…
A review of cultural heritage inspection: Toward terahertz from mid-infrared region
Pengfei Zhu, Hai Zhang, Stefano Sfarra +2
This review explores non-invasive imaging (NII) methods covering the mid- and far-infrared to the terahertz spectral regions (up to approximately 1000 um) for the detection and ana…
Modeling Terahertz Propagation via Frequency-Domain Physics-Informed Neural Networks
Pengfei Zhu, Hai Zhang, Stefano Sfarra +3
Terahertz time-domain spectroscopy (THz-TDS) provides a non-invasive and label-free method for probing the internal structure and electromagnetic response of materials. Numerical s…
Thermal diffusivity measurement based on evaporative cryocooling excitation: Theory and experiments
Pengfei Zhu, Hai Zhang, Stefano Sfarra +4
Photo-thermal methods for measuring thermal diffusivity inherently pose an ill-posed inverse problem, affected by factors such as sample thickness, heating or cooling time, and exc…
Thermal diffusivity characterization of impacted composites using evaporative cryocooling excitation and inverse physics-informed neural networks
Pengfei Zhu, Hai Zhang, Stefano Sfarra +5
The thermal diffusivity measurement of impacted composites using pulsed methods presents an ill-posed inverse problem influenced by multiple factors such as sample thickness, cooli…
