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: 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: The results show that, when present, the emission from traps can be used as an analytical tool to identify cadmium pigments, to distinguish among Cadmium sulfide, cad mium zinc sulfide), and cadMium sulfoselenide, and to map cadnium pigment, even in mixtures.

TL;DR: It is shown that combining the contrasts of multispectral and multidelay pump-probe spectroscopy permits nondestructive 3D imaging of paintings with molecular and structural contrast, even for pigments with linear absorption spectra that are broad and relatively featureless.

TL;DR: In this article, two novel hyperspectral cameras, one operating from the visible to near-infrared (VNIR) and the other in the shortwave infrared (SWIR), have been used to collect diffuse reflectance spectral image cubes on a variety of paintings.
