ABSTRACT:
An ultrasonic transducer for generating an apodized beam of ultrasonic energy. A piezoelectric crystal element mounted in a housing generates on ultrasonic signal when electrically energized. A tungsten-epoxy layer mounted on the outer surface of the piezoelectric crystal element has a greater thickness at the periphery of the element than at the center, thus yielding an outwardly concave surface. The tungsten-epoxy layer provides a more uniform beam pattern.
