Quantitative analysis of pigment mixtures on paper using fiber-optic reflectance spectroscopy and advanced optical modeling

Ricardo P. Vicente Rojas, Silvia Sotgiu, Véronique Cachia, Eugenio DelRe et autres

Non-invasive methods are essential for studying materials in cultural heritage artworks. Among them, Fiber Optic Reflectance Spectroscopy (FORS) is widely employed for in situ analysis due to its portability and direct relationship with the optical properties governing color. However, FORS remains largely …

Terahertz imaging super-resolution for documental heritage diagnostics

Danae Antunez-Vazquez, Laura Pilozzi, Eugenio Del Re, Claudio Conti et autres

Terahertz (THz) imaging is a non-invasive tool for cultural heritage diagnostics, but its spatial resolution is limited by diffraction. This study presents a super-resolution technique using structured illumination with a knife-edge (KE) in a reflective THz time-domain spectroscopy (THz-TDS) setup. By modulating …

Advancing fiber optics reflectance spectroscopy with remote detection

Mauro Missori, Chiara Casarin, Renata Codello, Guido Caldarelli

Non-invasive methods are essential for studying materials in cultural heritage artworks. Fibre Optic Reflectance Spectroscopy (FORS) is widely used for in situ analysis of opaque materials in reflectance mode. However, traditional FORS requires direct contact or close proximity to the artwork, limiting …
