Programma dettagliato e risultati di apprendimento attesi

Course objectives

Non destructive techniques are becoming more and more important in the monitoring and characterization of complex systems. The course presents a remote sensing approach for the imaging of the subsurface and the identification of specific targets. Different physical domains are studied from the basic principles up to the data collection and processing. The common framework is the generation and recording of a non destructive analysis signal (acoustic, elastic, electromagnetic) that propagates within the medium collecting information about its properties. Particular attention is posed on the identification of the observable parameters, on the resolution and reliability of the final image, on the potentiality of multi domain data integration (“big data”).

The course shows also current case histories and applications (identification of contaminant plumes, pipeline integrity monitoring, exploration for fluids, rescue of survivors under ruins, automatic tracking of acoustic sources).
