Thermography for the Diagnosis of Acute Inflammation in the Paranasal Sinus

open access: yesInternational Archives of Otorhinolaryngology, 2020
Introduction Although computed tomography scanning is the most common method for the diagnosis of sinusitis today, X-ray imaging is still used in outpatient clinics. Because X-ray imaging is beneficial for patients with severe sinusitis but not for those

Two-Color-Thermography for Temperature Determination in Laser Beam Welding of Low-Melting Materials

open access: yesSensors, 2023
Spatial and temporal knowledge of temperature evolution is crucial in laser beam welding of low-melting materials such as aluminum alloys. Current temperature measurements are restricted to (i) one-dimensional temperature information (e.g., ratio ...

Improvement the temperature signal filtering in lock-in thermography

open access: yesMATEC Web of Conferences, 2018
At present, lock-in thermography is widely used non-destructive method for defects detection. The informative images in lock-in thermography (e.g. phasegram) are obtained after temperature signal filtering of the raw data.
