Paper Abstract

Mexico possesses a large cultural heritage of paintings, elaborated after the European explorers encountered the New World. The interest in documenting these treasures was recently renewed, with the development of nondestructive remote techniques. We examined an undocumented painting for the presence of any invisible signatures, dates, or under-drawings. We employed several illumination-detection schemes, including IR broadband and LED arrays to achieve this purpose. We made visible the signature at about 1 μm and the date at 1.2 μm.
