Recent works have demonstrated the information potential of spectral imaging applied to complex heterogeneous ancient materials at various length scales from the centimetre to the nanometre [D. Thurrowgood, Sci. Rep., 2016 ; C. Ryan, J. Phys., 2014]. This post-doctoral project will allow deepening the relationship between structure, microenvironment, colour, and long-term behaviour available within the data collected in spectral imaging. The project will focus on archaeological and historical coloured stratified systems (ceramics). Further than mere chemical identification, we hypothesise that a better multiscale description of compound distribution, such as pigments and trace compounds will provide a clearer understanding of past supply of raw materials, manufacturing techniques, and alteration mechanisms [F. Meirer, J. Anal. At. Spectrom., 2014]. Data treatment will particularly be applied to high-definition fluorescence and absorption X-ray images, as well as electron microscopy analyses. Preliminarily, these approaches will be tested on simpler corrosion phases from archaeological copper-based artefacts, for which UV/visible photoluminescence imaging has recently revealed fossilized morphologies [M. Thoury et al., Nat. Comm., 2016]. High-contrast images were collected that show an heterogeneous distribution in crystal defect densities which morphology will be used to implement first developments of the proposed strategy at high spatial dynamics. In parallel to direct imagery indicating the distribution in space, positional correlation of these various signals will be performed. More specifically, this correlative analysis will be developed in the Fourier space in order to probe and filter the distinct length scales of organization.
This postdoctoral project will be carried out at IPANEMA (CNRS, MC, UVSQ) and at the Louvre museum.
The postdoctoral researcher will be member of a multidisciplinary team, including PhD students, interns and young researchers he/she could help supervise.
