Abstract

To obtain the high performances requested by the safety authorities for ultrasonic inspections, in term of sizing, characterization and on-line monitoring, it is needed to vary the refracted angles, focusing depths and the size of the ultrasonic beams rapidly and over a wide range. This is not possible with conventional techniques which allow only fixed focusing. The F.A.U.S.T. (Focusing Adaptive UltraSonic Tomography) system, which is described in this paper, is an open and powerful tool designed to overcome the difficult problems in flaw assessment and monitoring.
