ABSTRACT:
A sector scanner having an oscillating transducer element includes a motor and rotating shaft, a crank attached to an end of the shaft, and a linkage connecting the crank and the oscillating transducer element whereby rotation of the shaft is translated to oscillation of the transducer element. Vibration from the oscillating transducer element is minimized by reducing the mass of the oscillating element and employing harmonic motion of the transducer element.
