Abstract
In order to improve ultrasonic inspection, in terms of detection, sizing and characterization of defects, the French Atomic Energy Commission (CEA) has developed a dynamic adaptive focusing system called FAUST: Focusing Adaptive UltraSonic Tomography. This sytem is based on ultrasonic phased array transducers connected to a multi-channel acquisition system, which provides the delay and amplitude laws, allowing one to control dynamically the ultrasonic beam. This paper presents the general architecture of the system and some applications of it for defect characterization and improvement of the ultrasonic inspections.
