Using non-invasive non-destructive techniques to monitor cultural heritage objects

Cultural heritage plays a significant role in our identities and well-being. The aim of conservation is to manage change to cultural heritage objects. Non-destructive techniques offer an opportunity to quantify deterioration objectively and at an earlier stage than observation. There are limitations for using the techniques on precious artefacts. This paper examines some of the issues and opportunities through case studies with phased pulse thermography, acoustic emission, Fourier transform infrared spectroscopy and optical coherence tomography, applied to a series of mediaeval Limoges enamel plaques from the Werner Collection, displayed at Rangers House, London.
