Preparation of cross-section of micro samples, optical microscope documentation and infrared microscopy analysis.
The preparation of cross-sections of micro samples collected from an artwork, which is usually followed by visual documentation under optical microscope and molecular (infrared) analysis, it possible to obtain information on materials, execution technique, state of conservation and degradation processes on the artworks
Non-invasive in-situ analysis using multispectral imaging, X-ray fluorescence and infrared reflection spectroscopy (medium and near-infrared).
The combined use of portable and non-invasive analytical methods allows to characterize the state of conservation and the constituent materials of works of art. The approach with non-invasive in-situ techniques is fundamental for the analysis of art objects which, due to their size or high fragility, cannot be moved from their display location (Museums, Galleries ...).
Development of multivariate approaches for spectral and hyperspectral data processing.
The complexity of the analytical data obtained from the analysis of art objects often requires the use of multivariate approaches for the extrapolation of relevant information. Multivariate analysis is particularly valid for the extraction of information from spectroscopic data (infrared, XRF ...). The data may be collected from single-point analysis or from sequential acquisitions on well-defined areas (hyperspectral data).
