Multispectral and hyperspectral imaging technologies in conservation: current research and potential applications
TLDR
The published literature relating to the application of multispectral and hyperspectral imaging for the study and conservation of works of art is reviewed and some new perspectives offered by this innovative and fast-developing technology are presented.Abstract:
Spectral imaging technology, which records simultaneously spectral and spatial information about an object, was initially developed for remote sensing and has since been successfully applied to other areas of research. Although relatively new to the field of conservation, this non-invasive method of investigation has already provided promising results in the analysis of paintings and written documents, the characterization of materials and digital documentation. This article reviews the published literature relating to the application of multispectral and hyperspectral imaging for the study and conservation of works of art and presents some new perspectives offered by this innovative and fast-developing technology.read more

TL;DR: In this paper, it was shown that the mean optical path length in a particulate surface is in roughly inverse proportion to the square root of the absorption coefficient, and that absorption bands are Gaussians in shape when plotted as true absorptance vs photon energy, although they have a smaller intensity.

Moisture Effects on Soil Reflectance
David B. Lobell,Gregory P. Asner +1 more
TL;DR: In this paper, measurements of reflected shortwave radiation (400-2500 nm) were acquired in a laboratory setting for four different soils at various moisture contents, revealing a nonlinear dependence on moisture that was well described by an exponential model, and was similar for different soil types when moisture was expressed as degree of saturation.
