Abstract
Abstract An apparatus and a method of providing runout compensation for wobble present in the measurements made of the orientation of a rotary body relative to at least a pair of planes, and including at least a pair of sensors for providing measurements angularly related to each other and with the sensors coupled to the body for providing signals representative of the measurements of the rotary body relative to at least the pair of planes at a particular angular relationship. The body is rotated through a plurality of positions for providing signals representative of the measurement of the body relative to the pair of planes at the different positions. A first output signal is produced and is representative of the orientation of the body relative to one of the planes in accordance with the measurements at the different positions in the one plane and with the measurements in the one plane used to provide a runout compensation for wobble present in the measurements. A second output signal is produced and is representative of the orientation of the body relative to the other of the planes in accordance with the measurements at the different positions in both planes and with the measurements in the one plane used to provide a runout compensation for wobble present in the measurements in the other plane.
