A feedback sensor system (100) is provided. The feedback sensor system (100) includes a first ring (108) rotatable about an axial direction (A) and a second ring (110) also rotatable about the axial direction (A). The first ring (108) includes one or more first ring features (116) and the second ring (110) includes one or more second ring features (120). The feedback sensor system (100) also includes a sensor (112) directed at the surface (118) of the first ring (108) for sensing a parameter influenced by the one or more first ring features (116) and the one or more second ring features (120). The sensor (112) may determine a position of the first ring (108) relative to the second ring (110) by sensing the parameter. |
