Title (EN) ANGULAR POSITION ROTARY DETECTOR WITH DIGITAL OUTPUTS
(FR) CAPTEUR ROTATIF DE POSITION ANGULAIRE A SORTIES NUMERIQUES
Abstract:
(EN) The detector comprises a rotary disk provided with a plurality of circular concentric reading tracks each having two alternated series of sectors of two different types. Said tracks are read out by appropriate sensors (1, 2, A, B, C, D). One of said tracks is associated with Z1 sensors (A, B, C, D) allowing to define Z1 relative decoding bits, the other track or tracks using Z2 sensors (1, 2) allowing to determine high-order bits of the angular position of the disk as well as the relative order of bits issued from Z1 sensors. The invention allows to make detectors of reduced size and high resolution.
(FR) Le capteur fait intervenir un disque rotatif muni de plusieurs pistes de lecture circulaires concentriques comportant chacune deux séries alternées de secteurs de deux types différentes. Ces pistes sont lues par des détecteurs (1, 2, A, B, C, D) appropriées. L"une des pistes est associée à Z1 détecteurs (A, B, C, D) permettant de définir Z1 bits de décodage relatif, l"autre ou les autres pistes font intervenir Z2 détecteurs (1, 2) permettant de déterminer les bits de poids fort de la position angulaire du disque ainsi que le poids relatif des bits issus des Z1 détecteurs. L"invention permet de réaliser des capteurs de petites dimensions à haute résolution.
