Noninvasive full-field physics techniques for innovative violins inspection: first results from “AMATI VI(H)OLIN” project

The analysis of historical violins is very demanding and a holistic diagnostics involving different aspects, from conservation issues to acoustic behaviour, is auspicable. The AMATI VI(H)OLIN project, a Next GenerationEU funded research, gives the proof-of-concept of a novel integrated approach for surface, subsurface, and bulk analysis of violins. A nondestructive testing “suite” of contactless and full-field physics techniques for measuring violins in situ is presented, including laser interferometry techniques (shearography, holography, speckle imaging) coupled to consolidated diagnostic tools (3D scanning, thermography, laser profilometry). Additionally, a set of controlled mockups of historical violins has been realized as ground truth for testing material properties and surface variation. The holistic approach is demonstrated on a genuine ancient instrument. First results from the Project are presented.
