1. An absolute encoder for determining the position of a movable workpiece including a rotationally driven element, said absolute encoder comprising:

  • a movable transducer element adapted for coupling to said rotationally driven element, said transducer element having a characteristic profile that varies substantially continuously as a function of the angular position of said transducer element;

    a fixed sensor positioned to sense said characteristic profile to produce a substantially continuous output signal representative of the angular position of said transducer element; and

    wherein said characteristic profile varies substantially continuously from a minimum value at a first angular reference position through substantially 360°

    to a maximum value at a second angular reference position.
