1. A method for producing misalignment information as to centerlines of first and second in-line stationary shafts, said method comprising:

  • maintaining the shafts substantially stationary;

    rotating a sensed point through a plurality of first angular positions around the first shaft while maintaining the sensed point at a substantially constant radial distance away from the centerline of the second shaft;

    rotating a sensor through a plurality of second angular positions around the first shaft while maintaining the sensor at a substantially constant radial distance away from the centerline of the first shaft;

    coordinating the rotation of the sensed point and the sensor so that a plurality of the first angular positions correspond to a plurality of the second angular positions at corresponding times;

    sensing the sensed point with the sensor at a plurality of the corresponding angular positions around the first shaft;

    producing an output corresponding to radial distances along lines through the sensed point and perpendicular to the centerline of the first shaft when the sensed point is at each corresponding angular position; and

    producing information as to the misalignment of the centerlines of the shafts based upon the output at each corresponding angular position.
