Specifically, the performance of Visible-Near Infrared (VIS-NIR) Reflectance Imaging Spectroscopy (RIS) synchronized with three-dimensional (3D) acquisition is demonstrated in the study of a detached mural painting by Alessandro Botticelli. Synchronized sensing generates georeferenced data for simplified data treatment and interpretation. We show how such output data can provide key information to interpret important fresco surface and subsurface features (e.g., painting technique, material composition, pentimenti).<\/jats:p>","DOI":"10.3390\/s21041287","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T18:45:00Z","timestamp":1613155500000},"page":"1287","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Synchronized Hardware-Registered VIS-NIR Imaging Spectroscopy and 3D Sensing on a Fresco by Botticelli"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0790-4689","authenticated-orcid":false,"given":"Jana","family":"Striova","sequence":"first","affiliation":[{"name":"National Institute of Optics of the National Research Council of Italy, INO-CNR, Largo Enrico Fermi 6, 50125 Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9354-4055","authenticated-orcid":false,"given":"Luca","family":"Pezzati","sequence":"additional","affiliation":[{"name":"National Institute of Optics of the National Research Council of Italy, INO-CNR, Largo Enrico Fermi 6, 50125 Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enrico","family":"Pampaloni","sequence":"additional","affiliation":[{"name":"National Institute of Optics of the National Research Council of Italy, INO-CNR, Largo Enrico Fermi 6, 50125 Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raffaella","family":"Fontana","sequence":"additional","affiliation":[{"name":"National Institute of Optics of the National Research Council of Italy, INO-CNR, Largo Enrico Fermi 6, 50125 Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1711","DOI":"10.1364\/AO.7.001711","article-title":"Infrared Reflectography: A Method for the Examination of Paintings","volume":"7","year":"1968","journal-title":"Appl.
