Comparative examples of the evolution of thermal cameras in artwork diagnostics: an experimental perspective




IR-thermography, cultural heritage


In cultural heritage diagnostics, thermographic methods have gained great importance. The main reasons for their widespread use are the ability to allow remote and wide-field imaging of hidden features (such as structural defects, materials diversity, and deep alterations) as well as the vast possibility to gain additional information through quantitative data processing. The technological evolution of thermal cameras has also played a very important role. In this article, we want to discuss the effect that this evolution has had on cultural heritage diagnostics. We will do this from an experimental point of view, i.e., by comparing on laboratory models and then in a real case, the behavior of different thermal cameras.

Author Biography

Dario Ambrosini, University of L'Aquila

Dario Ambrosini received his degree in electronic engineering from the Sapienza University of Rome (Italy), where from 1993 to 1995 he was a collaborator with the Optics Laboratory headed by Prof. Franco Gori. Since 1995 he was an assistant professor with the Energetics Department (presently DIIIE, Department of Industrial and Information Engineering and Economics) of the University of L'Aquila, where he currently is a full professor. His research interests include flow visualization and heat and mass transfer, optical metrology and non-destructive testing, thermography, and digital image analysis. In these fields, he has published more than 250 papers in peer-reviewed international journals and national and international congresses. A member of UIT (Italian Union of Thermal-Fluid Dynamics), OPTICA, and Sigma Xi, D. Ambrosini is an associate editor of the journal Optics and Lasers in Engineering since December 2019. In 2013 he was elevated to the rank of OSA (currently OPTICA) Senior member.
He was the recipient (with G. Schirripa Spagnolo) of the 2001 SPIE Kingslake Medal and Prize and one of the recipients of the 2016 OSA Outstanding Reviewer recognition.
