Title
(EN) STEERABLE HYBRID DISPLAY USING A WAVEGUIDE
(FR) AFFICHAGE HYBRIDE ORIENTABLE UTILISANT UN GUIDE D'ONDES
Abstract
(EN)
A system including a steerable mirror, a waveguide, first optics, intermediate optics, and final optics. The system includes a first light path for a foveal image element, the first light path including the first optics, the steerable mirror to steer a position of the foveal image element to a particular orientation, intermediate optics, and the final optics to direct the foveal image element to an in-coupling region of the waveguide. The system further includes a second light path for a field image element, the second light path including final optics.

Le système comprend un premier trajet de lumière pour un élément d'image fovéal, le premier trajet de lumière comprenant la première optique, le miroir orientable pour diriger une position de l'élément d'image fovéal vers une orientation particulière, l'optique intermédiaire et l'optique finale pour diriger l'élément d'image fovéal vers une région de couplage dans le guide d'ondes. Le système comprend en outre un second trajet de lumière pour un élément d'image de champ, le second trajet de lumière comprenant une optique finale.
