Geometric survey and characterization of artifacts through portable devices: An experience of mobile laboratory inside the Aeolian Museum of Lipari

In the last decade portable devices for analyzes on Cultural Heritage (e.g. laser-scanners, spectroscopes, XRF) has reached levels of reliability such as to be able to replace benchtop instrumentation for survey in situ. One of the most effective application of these devices concerns the digitization and the diagnosis of artworks preserved inside museums. Indeed, moving art objects or finds from its place of preservation to specific laboratories can often result difficult due to several reasons as fragility, big sizes, risk of damage, lack of authorizations etc. The paper shows the results of a collaboration between the IPCF-CNR of Messina and the Archaeological Museum of Lipari aimed at the creation of a mobile laboratory for chemical analysis and 3D digitizing of finds presenting different issues. The activities have been carried out using two performing and contactless tools: a laser-scanner arm by Faro (sometimes in combination with an external camera) and a handheld Raman spectrometer by Brucker.
