Non destructive identification of art objects using multispectral images, spectra and acoustic microscopy

Abstract

The target of this PhD thesis is the development of a system for the non destructive reveal of the information that stems from the art objects internal paint layers (stratigraphy) with a resolution of 1-10μm. The reveal of the stratigraphy provides important information related to the technique and the materials used for the creation of them as well as previous restoration attempts, initial design, overpaintings and more. This information is up to now mainly acquired through analytical spectroscopic methods, which require a micro-sampling operation. Most of the times, the objects under study are highly valuable and therefore must not be subjected to any intervention. Consequently, Non Destructive Testing (NDT) techniques to acquire cross section (depth profile) information from the paint layers of artworks is imperative. The target was achieved using the combination of the acoustic microscopy with Ultra Violet, Visible, near Infrared and mid-Infrared (UV/VIS/nIR/mIR) diffuse reflectanc ...
