Konferensbidrag (refereegranskat)abstract
- Remote imaging measurements of laser-induced fluorescence have been performed, with application towards cultural heritage. Measurement campaigns have been performed at, e.g., the Coliseum in Rome. Differences in fluorescence spectra from different points were found and images corresponding to different features could be produced for thematic mapping.

Konferensbidrag (refereegranskat)abstract
- Laser-induced fluorescence for remote imaging of historical monuments is an established technique, which in this work has been used in measurement campaigns at the Coliseum and the Baptistery of San Giovanni in Laterano in Rome, Italy. The results presented here are examples that show that biodeteriogens can be monitored and that. materials can be identified. Also, cleaned and soiled areas on the stone can be localized and differences between soiling can be found, which may be useful in the sustainable conservation for mapping and evaluation.

Konferensbidrag (refereegranskat)abstract
- On site remote laser-induced fluorescence measurements have been performed with application towards non-movable objects. This paper describes 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.
