Congratulations to our colleague Raphaël Moreau on the successful defense of his doctoral thesis!

Raphaël’s thesis, titled “Characterization of Artists’ Pigment Palette and Technique using Multi-sensor Scanner and Machine Learning Methods” explored the integrated application of scanning X-ray Fluorescence (MA-XRF), Reflectance Imaging Spectroscopy (RIS) and Luminescence Imaging Spectroscopy (LIS) in the study of cultural heritage artefacts through the development of two innovative multi sensor scanners.

The novel multi sensor scanners allow for simultaneous MA-XRF/RIS/LIS data acquisition, gather an extended spectral signature of the probed material, grants global distance control during data acquisition, and allows for the integration of 3D data to take into account the shape of the studied CH artefact.

Raphaël’s scanners were tested on reference materials and on Byzantine and post-Byzantine Cypriot painted works of art. 

These combined approaches provide promising results for the fast and automated assessment of large datasets to facilitate the work of specialists, as well as offer a practical first step toward the concept of Heritage Augmented Object.
