TLDR
The mapping and identification of artists' materials in paintings using this method and the potential of reflection imaging spectroscopy, in particular if the shortwave infrared region is included along with information from luminescence imaging Spectroscopy are shown.Abstract:
Reflection imaging spectroscopy is a useful technique to remotely identify and map minerals and vegetation. Here we report on the mapping and identification of artists' materials in paintings using this method. Visible and infrared image cubes of Picasso's Harlequin Musician are collected using two hyperspectral cameras and combined into a single cube having 260 bands (441 to 1680 nm) and processed using convex geometry algorithms. The resulting 18 spectral end members are identified by comparison with library spectra, fitting by nonlinear mixing, and using results from luminescence imaging spectroscopy. The results are compared with those from X-ray fluorescence spectrometry, polarized light microscopy, and scanning electron microscopy–energy dispersive spectrometry (SEM/EDS). This work shows the potential of reflection imaging spectroscopy, in particular if the shortwave infrared region is included along with information from luminescence imaging spectroscopy.read more

TL;DR: In this article, a paradigm using multispectral visible and near-infrared imaging spectroscopy is presented to semi-automatically create unbiased spectral maps that guide the site selection for in situ analytical methods (e.g., fiber optic reflectance spectrograms and X-ray fluorescence) in order to identify and map pigments in illuminated manuscripts.

TL;DR: In this paper, the applicability of laser-induced fluorescence (LIF) spectroscopy as a nondestructive analytical technique for artwork diagnostics is investigated, which is shown to be suitable for differentiating among the various cadmium pigments used in this study and furthermore, to be capable of identifying individual components in mixtures of these pigments on the basis of their characteristic fluorescence emission.
