CHSOS just added a miniaturized spectrometer to its instrumentation. This system is equivalent to the ones tested already by CHSOS (Ocean Optics, BWTEK) and it will be used for pigments identification following the FORS (Fiber Optics Reflectance Spectroscopy) method. CHSOS chose a ASEQ LR1 spectrometer (300-1000 nm, 2nm resolution with 100um slit) This spectrometer weights just 430 gr and
A new free online FORS spectra database of pigments is available. FORS (Fiber Optics Reflectance Spectroscopy) is a low-cost spectroscopy and it is used to identify pigments on art works. CHSOS tested an innovative miniaturized and affordable spectrometer and created the spectral database. This new paper “FORS spectral database of historical pigments in different binders” introduces
Camilla Perondi took a training course on multispectral imaging last year and just recently she got her master degree in Science for the Conservation-Restoration of Cultural Heritage. I was her co-supervisor for her thesis “2D and 3D documentation, digital preservation and valorization of cultural objects using Digital Single-Lens Reflex cameras”. She presented as case studies the art
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
