Ensuring cultural heritage protection
Transit exhibitions and artwork loaning may lead to mistreatments or damages of art pieces, exposure to sudden environmental changes and to the risk of fraud.

 

A technology relying on holography, that involves measuring mechanical deformations, as signature of artworks has previously been developed to address the protection of cultural heritage. This technology has now found applications in art conservation. It was adopted for the follow-on cultural heritage EU-funded project SYDDARTA. The project aims to develop aprototype instrument for monitoring the deterioration of works of art and other heritage artefacts. It relies on an optical technique by which hyper-spectral images are acquired while simultaneously scanning the 3D profile of the object.

The original technology stems from MULTIENCODE, a research project funded by EU, involving the National Gallery of Athens and the TATE Gallery, London, UK. Completed in 2008, it led to the development of a hybrid portable device dubbed Impact Detection System-(IDS). This device works by relying on coherent laser metrology principle. It can trace impacts such as aging, effect of exposure to the environment, restoration interventions, and transportation. It can therefore identify an original artwork by retrieving and recording their unique characteristic features.
