Spectroscopy and imaging of ancient materials (ISMA)
Manager : Mathieu THOURY
Synchrotron experiments provide morphological, structural, chemical and elemental information, thanks to the energy resolution, low divergence and tunability of the beams produced. These features enable the use of high-resolution spectro-microscopy and tomography techniques to understand the multi-scale heterogeneity of ancient materials.
This axis focuses on :
- the development of new 2D and 3D analysis methodologies;
- the design of specific analytical couplings with the ambition of complete sample characterization;
- sample and sample population handling, and their analysis environments (particularly for in situ studies of re-created objects with a view to establishing model systems);
- sample location using non-invasive techniques.

To fully exploit the vast amounts of data produced by these experiments, the IPANEMA team is conducting original research into data processing, focusing on: :
- multivariate analysis of spectro-microscopy data, with a view to improving the quality of estimates made from this data ;
- the systematisation and automation of processing, to enable the characterisation of object corpora and achieve the reproducibility required for inter-corpus comparisons ;
- the combination of a priori information with measurement results to improve the quality of the models generated, particularly in tomography ;
- the development of algorithms enabling the combination of measurements taken in different modalities.
