Title (EN) COMPACT OPTICAL SYSTEM WITH MEMS SCANNERS FOR IMAGE GENERATION AND OBJECT TRACKING
(FR) SYSTÈME OPTIQUE COMPACT À DISPOSITIFS DE BALAYAGE MEMS POUR UNE GÉNÉRATION D'IMAGES ET UN SUIVI D'OBJET
Abstract:
(EN) An optical system that deploys micro electro mechanical system (MEMS) scanners to contemporaneously generate CG images and to scan a terrain of a real-world environment (112). An illumination engine (502) emits a first spectral bandwidth and a second spectral bandwidth into an optical assembly (500) along a common optical path (1). The optical assembly then separates the spectral bandwidth by directing the first spectral bandwidth onto an image-generation optical path (2) and the second spectral bandwidth onto a terrain-mapping optical path (7). The optical system deploys the MEMS scanners (214, 218) to generate CG images by directing the first spectral bandwidth within the image-generation optical path and also to irradiate a terrain by directing the second spectral bandwidth within the terrain-mapping optical path. Accordingly, the disclosed system provides substantial reductions in both weight and cost for systems such as, for example, augmented reality and virtual reality systems.
(FR) L'invention concerne un système optique qui utilise des dispositifs de balayage à microsystème électromécanique (MEMS) pour simultanément générer des images infographiques (CG) et balayer un terrain d'un environnement du monde réel (112). Un moteur d'éclairage (502) émet une première largeur de bande spectrale et une seconde largeur de bande spectrale dans un ensemble optique (500) le long d'un trajet optique commun (1). L'ensemble optique sépare ensuite la largeur de bande spectrale en dirigeant la première largeur de bande spectrale sur un trajet optique de génération d'images (2) et la seconde largeur de bande spectrale sur un trajet optique de cartographie de terrain (7). Le système optique utilise les dispositifs de balayage MEMS (214, 218) pour générer des images CG en dirigeant la première largeur de bande spectrale dans le trajet optique de génération d'images et également pour exposer un terrain à un rayonnement en dirigeant la seconde largeur de bande spectrale dans le trajet optique de cartographie de terrain. En conséquence, le système décrit offre des réductions importantes à la fois de poids et de coût pour des systèmes tels que, par exemple, des systèmes de réalité augmentée et de réalité virtuelle.
