Stacked denoising autoencoder for infrared thermography image enhancement
, 2021 Pulsed thermography is one of the most popular thermography inspection methods. During an experiment of pulsed thermography, a specimen is quickly heated, and infrared images are captured to provide information about the specimen's surface and subsurface

Modeling of Pulsed Thermography in Anisotropic Media
, 1999 As active thermography continues to gain acceptance as an NDE tool for both inservice and manufacturing applications, the need for robust physical models of the process increases. Although the sophistication of both analytical and numerical modeling efforts has increased considerably [1–3], development of a 3-dimensional model for anisotropic media is ...

Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters
Advanced Functional Materials, EarlyView.An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Pulsed Phase Thermography analysis on cylindrical geometry
Proceedings of the 2014 International Conference on Quantitative InfraRed Thermography, 2014 Goal of this work is the characterization of flaws in cylindrical geometry exploiting Pulse Phase Thermography (PPT), a Non-Destructive Testing method belonging to the Infrared Thermography category. The experiments are conducted on a hollow semicylindrical Plexiglas pipe section, with an outer and an inner diameter, respectively, of 150 mm and 130 mm.

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
Advanced Optical Materials, EarlyView.A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.
