Remote fluorescence lidar imaging of monuments: the Coliseum and the Lateran baptistery in Rome

On site remote laser induced fluorescence measurements have been performed with application towards non-movable objects. This paper gives an overview of the results obtained from the application of non-invasive hyperspectral fluorescence imaging to two masonry monuments, the Coliseum and the Lateran Baptistery in Rome, during a joint Italian-Swedish experiment. The mobile systems of Lund Institute of Technology, Sweden, and CNR-IFAC, Italy, were placed at the distance of 18-65 m from the façades for the documentation and characterization of surfaces, including materials, protective treatments, biodeteriogens and historic layers.
