AIR-COUPLED ULTRASONIC SYSTEM: A NEW TECHNOLOGY FOR DETECTING FLAWS IN PAINTINGS ON WOODEN PANELS

ALISON MURRAY, MARION F. MECKLENBURG, C. M. FORTUNKO, & ROBERT E. GREEN


ABSTRACT—Air-coupled ultrasound, a noncontact, nondestructive testing technique, has detected splits, checks, delaminations, cleavage, and voids in various materials. The system has inspected highly anisotropic and inhomogeneous materials such as wood and wood products, with surfaces layers of gesso, gesso and linen, paper, and wood veneer. Two paintings were tested; one was an oak-cradled panel painting and the other was illustration board mounted on hardboard. The air-coupled ultrasound technique yielded information additional to that provided by visual examination, xeroradiography, and infrared thermography.
