TL;DR: In this paper, the use of ultraviolet and visible diffuse reflectance spectrophotometry as a preliminary technique in the investigation of illuminated manuscripts is discussed, along with the benefits of extending the spectral range of analysis into the shortwave infrared (to 2500 nm).

TL;DR: 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.

TL;DR: This Account reports on the research activity carried out by two research groups, one at the "Nello Carrara" Institute of Applied Physics of the Italian National Research Council in Florence and the other at the National Gallery of Art in Washington, D.C, to develop multispectral and hyperspectral imaging systems to study works of art.

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: NIR reflectance imaging spectroscopy is a useful technique that can identify and map paint binding media based on differences in chemical composition and is demonstrated to be in agreement with prior site-specific amino acid analysis.
