Abstract[English]
The present disclosure relates to an optical eye tracking system for a virtual reality display comprising: a light guide; an in-coupling diffractive optical element arranged to receive reflected light from an object and couple the reflected light into the lightguide at a first location, wherein the reflected light propagates around the light guide and exits the light guide at a second location; and a light detector arranged proximal to the second location to receive the reflected light from the light guide, wherein the light guide is arranged in a pancake lens system.[French]
La présente divulgation concerne un système d'oculométrie optique pour dispositif d'affichage de réalité virtuelle, celui-ci comprenant : un guide de lumière ; un élément optique diffractif de couplage conçu pour recevoir une lumière réfléchie par un objet et pour introduire la lumière réfléchie dans le guide de lumière au niveau d'un premier emplacement, la lumière réfléchie se propageant partout dans le guide de lumière et sortant du guide de lumière au niveau d'un second emplacement ; et un détecteur de lumière disposé à proximité du second emplacement afin de recevoir la lumière réfléchie par le guide de lumière, le guide de lumière étant disposé dans un système d'objectif pancake.
