Paper Abstract

Sandwich holography has been just used in artwork conservation; its capability in detecting incipient faults or cracks in wooden panel paintings and statues has been tested successfully on models and ancient artifacts under restoration; a part from its ability to render significant services in non destructive inspection, sandwich hologram is expected to find application in other problems having considerable interest as displacement derivative measurement. The purpose of this paper is to extend this simple method of measurement to the study of lining canvas behaviour under a slight mechanical stress, in order to characterize the material employed to line painted canvases, both for improving the existing techniques and for selecting new materials. Some preliminary experimental results on models of lining canvases are presented.
