摘要：
When transiently-excited, thick ultrasonic source transducers are used in NDE applications, such as broadband measurements of attenuation or of directivity and frequency responses of receiving transducers, the pulser must provide an excitation pulse that is very short and of high voltage and current Also, it is desirable that the pulser be of simple and stable design. Features of several designs, including modem FET pulser circuits, are discussed.
