Paper Abstract

Fluorescence lidar imaging can be regarded as an effective tool for early diagnostics and documentation of the outdoor cultural heritage, with the aim of a correct planning of conservation and restoration of monuments. In this paper we present the latest advancements on fluorescence hyperspectral lidar imaging recently achieved at IFAC-CNR in terms of instrumentation and novel applications. In particular, the paper focuses on the upgrading of some key technical features, such as: the scan speed of the sensor, spatial resolution at the surface and field of view of the instrument. The upgrading of these technical characteristics has also made it possible to successfully extend the applicability of the technique to the diagnostics on wall paintings, which requires an improved spatial resolution. Finally, we outline the potential of a new concept of fluorescence lidar imaging system, based on the integration of hyperspectral and fluorescence lifetime spectroscopy, which enhances the capabilities of the technique for the characterization of the materials to be investigated in cultural heritage assets.
