Abstract: A multi-pole annular encoder having 2N poles distributed irregularly is positioned facing a sensor that detects transitions between the poles. Times corresponding to the detected transitions are stored and the times that have elapsed between each transition and the previous transition of order 2N, which constitute durations for a complete revolution of a rotating member, are calculated. When the durations thus calculated are stable, a time that has elapsed between a tested transition and the previous transition is calculated, and a characteristic angle of the tested transition is deduced therefrom, this being proportional to a ratio between a time that has elapsed since the previous transition and a stabilized duration for a complete revolution. An index transition is identified and is used to ascertain absolute position of the encoder with respect to the sensor.
