FORS, Fiber Optics Reflectance Spectroscopy con gli spettrometri miniaturizzati per l’identificazione dei pigmenti

Fors, Fiber Optics Reflectance Spectroscopy (for Italian readers)

Published on Archeomatica, 1 Marzo 2014  a paper, for Italian readers, introducing the miniaturized spectrometers for Fiber Optics Reflectance Spectroscopy. This paper shows the results of the testing of a FORS (Fiber Optics Reflectance Spectroscopy) system assembled with Ocean Optics components and featuring a USB4000 miniaturized and low cost spectrometer. The small dimensions and little

Identification of pigments by multispectral imaging: a flowchart method

A paper on Multispectral Imaging has been published on Heritage Science, “Identification of pigments by multispectral imaging a flowchart method” 2:8, 2014. In this paper I provide a flowchart method to use the multispectral imaging to tentatively identify pigments. I have been posting extensively on this idea for a while on the “Cultural Heritage Science Open
