ABSTRACT:
An ultrasonic driver transducer employs a piezoelectric element excited by pulsed carrier signals and generates a propagating ultrasonic wave focused in acoustically matched relation by a metal plano-concave lens through a liquid medium for collimated flow into a metal coupler output element and then into the external specimen or element that is to be excited by ultrasonic energy. Means are provided for filling internal cavities of the instrument with a liquid medium for propagating only the desired waves, along with means for purging entrapped gas from that interior medium.
