Abstract

La présente invention concerne un système optique comprenant un guide d'ondes optique, et un premier élément optique configuré pour diriger un premier rayon, ayant une première polarisation circulaire et étant incident sur le premier élément optique à un premier angle d'incidence, dans une première direction de telle sorte que le premier rayon se propage à travers le guide d'ondes optique par l'intermédiaire d'une réflexion interne totale vers un second élément optique. Le premier élément optique est configuré pour diriger également un second rayon, ayant une seconde polarisation circulaire qui est distincte de la première polarisation circulaire et est incident sur le premier élément optique au premier angle d'incidence, dans une seconde direction qui est distincte de la première direction de sorte que le second rayon se propage à l'opposé du second élément optique. Le second élément optique est conçu pour diriger le premier rayon qui se propage à travers le guide d'ondes optique vers un détecteur.
