Optical Coherence Tomography for Non-Destructive Investigations of Structure of Objects of Art

NDT Database & The e Oct 14 2008 Art

In this contribution the Optical Coherence Tomography (OCT), as a novel tool for non-invasive structural imaging of selected objects of cultural heritage, will be reviewed. This technique relies on multispectral interference o f infrared light and therefore is well suited for investigation of transparent and semi-transparent structures. The technique originates from medical imaging and has been present in conservation science since 2004. Until now it has been successfully utilized in imaging of varnishes, glazes and underdrawings of paintings, glazes on porcelain and faience, structure of archaic jades, stained and archeological glass, parchment and recently for revealing the surface details of ...
