Abstract :
Terahertz time-domain reflectometry has been applied to the investigation of a medieval Danish wall painting. The technique has been able to detect the presence of carbon-black layer on the surface of the wall painting and a buried insertion characterized by high reflectivity values has been found in depth of the lime-based historical plaster.
