“…The multispectral scanner developed at the National Research Council–National Institute of Optics (CNR-INO) allows for the simultaneous acquisition of 32 narrow-band images (16 VIS and 16 NIR images) through whiskbroom scanning in the range of 390–2500 nm [ 20 , 21 ]. A square-shaped fibre bundle collects the reflected light from a single point of the scanned surface and delivers it to a set of Si and InGaAs photodiodes, each of them equipped with an interferential filter.…”

Fayum mummy portraits, painted around 2000 years ago, represent a fascinating fusion of Egyptian and Graeco-Roman funerary and artistic traditions. Examination of these artworks may provide insight into the Roman Empire’s trade and economic and social structure during one of its most crucial yet still hazy times of transition. The lack of proper archaeological documentation of the numerous excavated portraits currently prevents their chronological dating, be it absolute or relative. So far, their production period has been defined essentially on the basis of the relevant differences in their pictorial style. Our study introduces the use of Accelerator Mass Spectrometry (AMS) to assess the age of a fragment of an encaustic painting belonging to the corpus of the Fayum portraits. The unexpected age resulting from 14C analysis suggests the need to reconsider previous assumptions regarding the period of production of the Fayum corpus. Furthermore, our multi-analytical, non-invasive approach yields further details regarding the fragment’s pictorial technique and constituting materials, based on spectral and morphological analysis and cross-sectional examination.

“…The multispectral scanner [ 36 ] developed at CNR-INO operates in the range 395–2550 nm providing simultaneously 32 narrow-band images (16 VIS + 16 NIR) and pointwise spectral information. The simultaneous movement of both the lighting system and collecting optics, placed in a 45°/0° illumination/detection geometry, allows for uniform illumination and minimal heating of the surface.…”

Reflectance Spectroscopy as a Novel Tool for Thickness Measurements of Paint Layers

A major challenge in heritage science is the non-invasive cross-sectional analysis of paintings. When low-energy probes are used, the presence of opaque media can significantly hinder the penetration of incident radiation, as well as the collection of the backscattered signal. Currently, no technique is capable of uniquely and noninvasively measuring the micrometric thickness of heterogeneous materials, such as pictorial layers, for any painting material. The aim of this work was to explore the possibility of extracting stratigraphic information from reflectance spectra obtained by diffuse reflectance spectroscopy (DRS). We tested the proposed approach on single layers of ten pure acrylic paints. The chemical composition of each paint was first characterised by micro-Raman and laser-induced breakdown spectroscopies. The spectral behaviour was analysed by both Fibre Optics Reflectance Spectroscopy (FORS) and Vis-NIR multispectral reflectance imaging. We showed that there is a clear correlation between the spectral response of acrylic paint layers and their micrometric thickness, which was previously measured by Optical Coherence Tomography (OCT). Based on significant spectral features, exponential functions of reflectance vs. thickness were obtained for each paint, which can be used as calibration curves for thickness measurements. To the best of our knowledge, similar approaches for cross-sectional measurements of paint layers have never been tested.

“…The maximum scanned area was 1 m 2 (carried out in 3 h) with 250 μm of spatial sampling; mosaicking was needed for bigger areas. 28 In the cases of “The Holy Family with St. Anne and the Young St. John” (0.92 × 1.16 m 2 ) and of “The Child with the Lamb” (0.28 × 0.25 m 2 ), a single set of images of 3690 × 4645 and 2074 × 2298 pixels, respectively, was acquired. The 16 images in the VIS range were combined (using the standard D65 illuminant and 1931 observer) in order to obtain the red-green-blue (RGB) images (Figs.…”
