Abstract
Electronic Speckle Pattern Interferometry (ESPI) is a well-known tool in cultural heritage diagnostics. It can also reveal cracks and debonding of tiles in ancient mosaics of roman and medieval age. This paper describes a portable electro-optic system (it integrates the ESPI and local speckle correlation techniques) as a diagnostic tool to evaluate the state of conservation of ancient mosaic. Some experiments are been carried out on real, ancient, mosaics in laboratory and in situ.
