Abstract
A TV-holography system is designed to monitor detached plaster areas in historical murals. Defects in the wall respond to sound irradiation by vibrations. These are detected optically. A feature of the system is the enhanced sensitivity obtained by reference wave modulation. Experimental results obtained at a historical site show very good agreement with data gained by the traditional percussion method.
