Abstract
An optical encoder for which improved robustness is sought comprises: a movable part bearing a scattering zone and an absorbing zone, a light emitter that is positioned to emit light radiation in the direction of the movable part, a sensor that is sensitive to the light emitted by the emitter, the sensor being positioned to detect light radiation that is reflected by the scattering zone, the movement of the movable part making it possible to place either the scattering zone or the absorbing zone on an optical path between the emitter and the sensor, and an optical waveguide that is transparent to the light radiation and that is passed through by the optical path.
