Abstract

Research being performed to develop a viable noncontacting NDE technique for measuring the extent of bonding has led to the development of a laser sensor field system. The noncontacting laser sensor has been used to collect data from diffuse surfaces, such as the Thermal Protection System (TPS) tile on the space shuttle orbiter. The bonded material gently excited with an acoustic signal, and the displacement is detected and related to the degree of bond.
