23 June 1995 Monitoring of plaster detachments in historical murals using TV holography
Author Affiliations +
Deterioration of historical murals often leads to partial detachments of the paint carrying plaster layers. To identify such regions an acousto-optical method is described. Loose portions of the plaster are excited by sound waves and the resulting vibrations are detected by sensitized analog TV-holography.
