We propose a non-invasive approach for the study of illuminated manuscripts based on the combination of near-infrared reflectance imaging, X-ray fluorescence mapping, and Raman spectroscopy. Taking advantage of the different absorption coefficient of the characteristic X-ray emission lines of a specific element, we have implemented a differential mapping method to distinguish the X-ray emissions from...
Macro X-ray fluorescence scanning (MA-XRF) is gradually becoming an established technique for the non-invasive analytical investigation of painted surfaces. This paper discusses some of the benefits and limitations of employing MA-XRF for the study of manuscript illuminations. Art historical research on this type of artefacts that is based on scientific measurements is often limited by the fact that...
