TLDR
To identify materials on a painting's surface in a reliable manner, currently the most popular and trustworthy method is the analysis of microsamples of the paint layer, however, chemical analyses although reliable, have a number of drawbacks.Abstract:
Identifying the materials of a painting is a crucial step in any conservation process. When the objective is to prepare an intervention plan, it is absolutely necessary to understand the matters the restorer is going to encounter. Also, when the aim is a better understanding of the artwork, and perhaps an authenticity check, it is highly relevant to know which materials were employed, since they may differ depending on the period of execution and on the specific artist as well. To identify materials on a painting's surface in a reliable manner, currently the most popular and trustworthy method is the analysis of microsamples of the paint layer. However, chemical analyses although reliable, have a number of drawbacks. The first is linked to the fact that this is an invasive method. The samples used need to be detached from the painting and will not be put back in place. Moreover, the achieved results are in principle - and often also in practice - valid only for that specific specimen and cannot generally be extended to neighboring areas.read more

DMD-based implementation of patterned optical filter arrays for compressive spectral imaging
TL;DR: The framework of CSI is extended by replacing the traditional block-unblock photomasks by patterned optical filter arrays, referred to as colored coded apertures (CCAs), which allow the source to be modulated not only spatially but spectrally as well, entailing more powerful coding strategies.

Distance metrics and band selection in hyperspectral processing with applications to material identification and spectral libraries
TL;DR: This paper derives a technique called band add-on (BAO) that iteratively selects bands to increase the angular separation between two spectra and demonstrates that band selection can improve the discrimination of very similar targets, while using only a fraction of the available spectral bands.
