(EN)Systems and methods for implementing an absolute encoder are disclosed. A system can include a plurality of tracks (12, 14), each having a plurality of track elements (20, 22). Track elements (22) for at least one of the tracks (14) are configured with a nonlinear modulation, such that an absolute position can be determined without requiring a reference marker.
