The C2RMF has acquired a imaging system of thermally stimulated luminescence (TL) and optically stimulated luminescence (OSL) for heritage materials. The use of TL/OSL imaging is challenging due to the low light intensity and the fast kinetics of the observed phenomena.

Conclusion
The main hardware parameters have been optimized. Binning, time exposure, temperature cooling being sample dependent. The next step is to improve image processing for low-intensity measurements (sample irradiated around 1 Gy).
The system can already be used for qualitative studies of polymineral samples in various forms C2RMF
