A position sensing apparatus and method, motion control system, and integrated circuit are provided that include a plurality of sensors and a tracking processor. The plurality of sensors includes a linear array of sensors that sense a plurality of features of an object. A spacing between two of the plurality of sensors is substantially smaller than a spacing between two of the plurality of features. The tracking processor samples signals from the sensors, compares the samples to previous samples and calculates a position of the object. The plurality of sensors may include a second linear array of sensors. Centers of the sensors of the second linear array may be offset from centers of the sensors of the first linear array along a longitudinal axis of the plurality of sensors.
