"2D and 3D optical techniques for manuscript analysis: diagnostics based on data integration"

Nothing like an ancient manuscript, passed from hand to hand over the centuries, better represents the legacy of history. Researchers are called to advance the techniques that allow the interpretation of this ancient heritage. This work sets out the methodology for performing comprehensive data analysis through the integration of 2D and 3D optical techniques. The approach involves the use of traditional UV-VIS-NIR imaging, combined with SWIR imaging, and the recent Thermal Quasi-Reflectography technique. In addition to examining the spectral signature, the investigation also employs a microsurface perspective, i.e., the imaging is integrated with surface topography.
