  • Using doppler techniques to measure non-uniform rotation of an ultrasound transducer
    Patent number: 5989191
    Abstract: According to one embodiment, an apparatus for measuring rotational velocity includes a support member, a transducer, and a Doppler shift measurement module. The transducer, which is supported by the support member, emits a first wave and detects a corresponding second wave reflected by matter intercepted thereby as the support member rotates continuously about an axis of rotation. The Doppler shift measurement module measures frequency shifting between the first wave and the second wave as the support member rotates about the axis of rotation, the frequency shifting being indicative of a rotational velocity of the support member relative to the matter.
