Comparison of Methods for Emissivity Influence Suppression on Thermographic Data

open access: yesBuildings, 2022
Emissivity is a crucial parameter for a quantitative thermography measurement. It influences measured temperature using an infrared camera. Typically, the emissivity is handled by infrared camera software but often for more complex tasks—e.g., setting ...

Thermal response of jointed rock masses inferred from infrared thermographic surveying (Acuto test-site, Italy) [PDF]

open access: yes, 2018
The Mediterranean region is affected by considerable daily and seasonal temperature variations due to intense solar radiation. In mid-seasons, thermal excursions can exceed tens of degrees thus influencing the long-term behaviour of jointed rock masses ...

A local defect resonance for linear and nonlinear ultrasonic thermography [PDF]

open access: yes, 2014
An efficient wave-defect interaction is the key to a high thermal response of flaws in ultrasonic thermography. To selectively enhance defect vibrations a concept of local defect resonance is developed and applied to ultrasonic activation of defects ...
