Research on ultrasonic standards at ETL - ultrasonic power measurement system by using radiation force method

摘要

In this paper, the authors have proposed a conical absorbing target for ultrasonic power measurements by using the radiation force balance method. We have compared three types of targets, i.e., a conical reflecting target, a plane absorbing target and a conical absorbing target. As results of experiments, the conical absorbing target showed some good characteristics for the precise ultrasonic power measurement system.
