Nondestructive stratigraphy determination artworks using system modeling

This paper presents the nondestructive stratigraphy determination through the use of UV/VIS/nIR spectroscopy. The UV/VIS/nIR backscattered light through a multilayered structure, such as the paint layers of artworks, is simulated. The device used to produce and measure the backscattered light, is the Perkin-Elmer Lambda 900 UV/VIS/nIR spectrophotometer equipped with an external integration sphere for "in situ" nondestructive measurements. The final target of this work is the development of a nondestructive technique to permit the stratigraphy reconstruction of artworks.
