Abstract :
In this paper, we briefly present two particular experiments based on time-reversal of ultrasonic fields; it shows how the phased array technology can be applied to ultrasonic systems. The method has been widely tested and is robust for defect detection, target location, even in the case of complex or very noisy systems
