TV-Holography in Artwork Diagnostics

抄録

TV-holography can hold a great potential in non-destructive diagnostics of the state of conservation and preservation of artworks. Its use in revealing debonds, cracks, voids, delaminations or residual stress in both ancient paintings on wooden panels, statuaries and mural supports has been proven. The method is easy to apply and very functional for the basic objectives of conservation; its compactness enables detection of microdisplacements even in non laboratory environments. Measurements in field of microcracks and subsurface detachments on ancient frescoes and panel paintings are reported.
