Report

Accurate three dimensional characterization of ultrasonic sound fields (by computer controlled rotational scanning)

By Gundtoft, Hans Erik1; Nielsen, T.1

From

Risø National Laboratory for Sustainable Energy, Technical University of Denmark1

A rotational scanning system has recently been developed at Risø National Laboratory. It allows sound fields from ultrasonic transducers to be examined in 3 dimensions. Using different calculation and plotting programs, any section in the sound field can be plotted. Results from examination of transducers for automatic inspection are presented.
