    摘要: La présente invention concerne un capteur rotatif optique de mesure de position angulaire absolue destiné à être utilisé en combinaison avec des moteurs miniatures tournant à des vitesses de plusieurs centaines de milliers de tours/minute. La plupart des capteurs de position rotatifs actuels utilisent un disque fixé au rotor, sur lequel est marqué un code, ainsi qu'un capteur qui lit la valeur du code à un ou plusieurs endroits particuliers du disque. Contrairement à ces capteurs, le système proposé utilise la totalité du marquage du disque pour le calcul de la position absolue. Cette particularité confère à l'invention plusieurs avantages, dont certains sont cumulables :
    • dimension très faible du capteur,
    • possibilité d'atteindre des vitesses de rotation de l'ordre de 600'000 tours/min,
    • augmentation de la résolution par interpolation si le flou de mouvement est négligeable, c.à.d. à des vitesses de rotation réduites (max 20'000 tours/min),
    • compensation automatique du décentrage de l'axe,
    • calibration adaptative en fonction de la non-uniformité de l'éclairage et du fixed-pattern du capteur d'image.

    摘要: The present invention concerns a method for working out at least the angular position of a rotating element which is mounted in a fixed frame, consisting in using at least one fixed light source emitting a beam of light in the direction of a fixed sensor, arranging the light source with respect to the rotating element and of the sensor in a way so as to induce an interaction between the beam of light and the sensor, which depends on the angular and the radial position of the rotating element and using computing and processing means for providing a value of the angular position dependent of the output signal of the sensor, characterized in that it consists in:
    a) arranging on the path of the beam of light a code-disc which presents a regular two dimensional pattern of transparent and opaque areas and an absolute code and which is integral in rotation with the rotating element,
    b) using the image casted by the code-disc on the sensor for determining the eccentricity of the code-disc in dependence of the angular position of the rotating element,
    c) using the eccentricity for compensating the value of the computed angular position,
    d) and computing a corrected angular position of the rotating element.
