Imaging by Ultraviolet (UV) fluorescenceSince the UV radiation has a short wavelengths than the visible light, so by using a UV-fluorescence, it is possible to identify multiple paint layers. Previous practical applications showed that the UV imaging is advantageous in detecting any retouching, varnishes, successive over-paintings and old restorations (Rizzutto et al., 2015). In fact, pigments usually show characteristic fluorescent hues when impacted to a UV light. For example, minium (Pb2O5) = orange fluorescence, while azurite = deep blue fluorescence,…...
