Description

The air-coupled ultrasonic transducers and their applications to ranging, robotic vision and nondestructive testing etc. have been widely studied in recent years. Further studies should be concentrated on (1) the improvement of the sensitivity and bandwidth of the transducers, (2) the prediction and measurement method of the radiation pattern. Much attention has been paid to the former problem about the transduction. However, the second problem, related to the measurement techniques of acoustic pressure distribution, is not well studied.
