A recent study, “Spatially registered 3D and sequentially shifted Raman mapping for painted surface characterization“, presents a new platform that integrates 3D surface scanning with SSETM Raman mapping to analyse painted surfaces non-invasively and with high spatial accuracy.
Designed for hardware-registered data acquisition, the system enables automated macro-Raman acquisition, ensuring precise focus and co-registration even on uneven surfaces. Using SSETM enables the suppression of fluorescence, a common limitation when analyzing modern or synthetic pigments.
Tested first on acrylic mock-ups and then on a painting, the platform demonstrated improved data quality, accurate material mapping, and reliable performance in high-fluorescence areas.
Designed with a modular architecture, the system can be expanded to integrate additional imaging techniques, making it a promising tool for advanced analysis in conservation science.
