Prototype designed to merge Laser-induced breakdown spectroscopy (LIBS), laser-induced fluorescence spectroscopy (LIF), Raman spectroscopy using a single pulsed laser, and reflectance spectroscopy in a multi-spectral characterization system for cultural heritage analysis (SYSPECTRAL). The aim is to analyze cultural heritage materials in their original place, obtaining both elemental and molecular information at such same point that is not always insured with several separated experimental settings.

Optical Coherence Tomography (OCT) is an non-invasive imaging technique that uses light to capture high-resolution, cross-sectional images of translucent or transparent materials at around 880 nm. OCT is a technique that is often described as "optical ultrasound". It uses interferometry to detect light reflections within the sample, enabling detailed visualisation of internal microstructures with axial resolutions of under 10 μm. OCT is an advanced technology that can produce clear 3D reconstructions. It provides live, near-microscopic images without requiring physical contact, sample preparation, or ionizing radiation. Though its imaging depths are limited to 1–2 mm, OCT is highly valuable in cultural heritage diagnostics and research due to its safety, precision and ease of use.
