Title (EN) LIDAR WITH CO-ALIGNED TRANSMIT AND RECEIVE PATHS
(FR) LIDAR À TRAJETS D'ÉMISSION ET DE RÉCEPTION COALIGNÉS
Abstract:
(EN) One example system includes a light source that emits light. The system also includes a waveguide that guides the emitted light from a first side of the waveguide toward a second side of the waveguide opposite the first side. The waveguide has a third side extending between the first side and the second side. The system also includes a mirror that reflects the guided light toward the third side of the waveguide. At least a portion of the reflected light propagates out of the waveguide toward a scene. The system also includes a light detector, and a lens that focuses light from the scene toward the waveguide and the light detector.
(FR) L'invention concerne un système illustratif qui comprend une source de lumière qui émet de la lumière. Le système comprend également un guide d'ondes qui guide la lumière émise d'un premier côté du guide d'ondes vers un deuxième côté du guide d'ondes opposé au premier côté. Le guide d'ondes présente un troisième côté s'étendant entre le premier côté et le deuxième côté. Le système comprend également un miroir qui réfléchit la lumière guidée vers le troisième côté du guide d'ondes. Au moins une partie de la lumière réfléchie se propage hors du guide d'ondes vers une scène. Le système comprend également un détecteur de lumière, et une lentille qui concentre la lumière de la scène vers le guide d'ondes et le détecteur de lumière.
