Remote thermographic inspection of wind turbines, either from the ground or from the air (drones), has great potential for condition monitoring throughout their entire service life However, the formation of measurable thermal contrasts on individual components depends heavily on dynamic weather conditions. A systematic and quantitative description of the observed effects is missing in...
Numerical modelling of thermography experiments traditionally relies on finite-element and heat-transfer simulations to predict temperature fields and defect signatures. However, the subsequent image formation process—governed by surface emissivity, reflection, transmission, viewing geometry and spectral camera response—is often treated only approximately. In this work we present a...
Infrared cameras are widely used in scientific research and industrial applications for temperature measurement and thermal analysis. For quantitative purposes, it is essential to adopt an appropriate radiometric model that accurately represents both the measurement conditions and specific properties of the target object. The diffuse-gray body approximation is commonly used in conventional...
