Abstract
La présente invention concerne un capteur de glucose qui comprend une source d'énergie optique ayant un émetteur avec un motif d'émission ; un premier polariseur coupant le motif d'émission ; un deuxième polariseur espacé à une distance du premier polariseur et coupant le motif d'émission, le deuxième polariseur étant tourné par rapport au premier polariseur d'une première quantité de rotation T ; un premier détecteur optique coupant le motif d'émission ; un deuxième détecteur optique positionné à proximité du deuxième polariseur, le premier polariseur et le deuxième polariseur étant positionnés entre la source d'énergie optique et le deuxième détecteur optique, le deuxième détecteur optique coupant le motif d'émission ; un circuit de compensation couplé au deuxième détecteur optique ; et un circuit soustracteur couplé au circuit de compensation et au premier détecteur optique.
