Mapping covered paints with Transmittance spectroscopy and transmitted multispectral imaging

How to identify and map covered paints on translucent support, such as canvases? We just published:  A. Cosentino “Transmittance spectroscopy and transmitted multispectral imaging to map covered paints” Conservar Património 24, 37-45, 2016. doi:10.14568/cp2015021 Transmitted spectroscopy and transmitted multispectral imaging in the 400-900 nm range have been applied for the mapping and tentatively […]
