Title (EN) SHARED WAVEGUIDE FOR A LIDAR TRANSMITTER AND RECEIVER
(FR) GUIDE D'ONDES PARTAGÉ POUR ÉMETTEUR ET RÉCEPTEUR LIDAR
Abstract:
(EN) One example system includes a light source that emits a light beam. The system also includes a waveguide that guides the emitted light beam toward an aperture. The system also includes a lens that directs the light beam, guided by the waveguide and transmitted through the aperture, toward a scene. The lens also receives light propagating from the scene toward the lens. The lens focuses the received light into the aperture. The waveguide also guides the focused light transmitted through the aperture. The system also includes a light detector. The waveguide transmits at least a portion of the focused light out of the waveguide and toward the light detector.
(FR) L'invention concerne un système illustratif qui comprend une source de lumière qui émet un faisceau de lumière. Le système comprend également un guide d'ondes qui guide le faisceau de lumière émis vers une ouverture. Le système comprend également une lentille qui dirige le faisceau de lumière, guidé par le guide d'ondes et transmis à travers l'ouverture, vers une scène. La lentille reçoit également la lumière se propageant à partir de la scène vers la lentille. La lentille focalise la lumière reçue dans l'ouverture. Le guide d'ondes guide également la lumière focalisée transmise à travers l'ouverture. Le système comprend également un détecteur de lumière. Le guide d'ondes transmet au moins une partie de la lumière focalisée hors du guide d'ondes et vers le détecteur de lumière.
