Beschreibung
Zusammenfassung:	A photonic proximity sensor and photonic sensor system are provided. The photonic proximity sensor includes a first light source, a second light source, and a magneto-optic device. The magneto-optic device receives light emitted from the first and second light sources, and is responsive to variations of a magnetic field to rotate the light from one of the sources significantly more than the light from the other light source. L'invention concerne un détecteur photonique de proximité et un système de détection photonique. Le détecteur photonique de proximité comprend une première source lumineuse, une seconde source lumineuse et un dispositif magnéto-optique. Le dispositif magnéto-optique reçoit la lumière émise par les première et seconde sources lumineuses et est sensible aux variations d'un champ magnétique faisant tourner davantage la lumière provenant d'une des sources lumineuses que celle provenant de l'autre source.
