要約
(EN) The present disclosure describes a system and method for a binocular LiDAR system. The system includes a light source, a beam steering apparatus, a receiving lens, a light detector. The light source is configured to transmit a pulse of light. The beam steering apparatus is configured to steer the pulse of light in at least one of vertical and horizontal directions along an optical path. The lens is configured to direct the collected scattered light to the light detector. The electrical processing and computing device is electrically coupled to light source and the light detector. The light detector is configured to minimize the background noise. The distance to the object is based on a time difference between transmitting the light pulse and detecting scattered light.
(FR) La présente invention concerne un système et un procédé pour un système de lira binoculaire. Le système comprend une source lumineuse, un appareil d'orientation de faisceau, une lentille de réception, un détecteur de lumière. La source lumineuse est conçue pour émettre une impulsion de lumière. L'appareil d'orientation de faisceau est conçu pour orienter l'impulsion de lumière dans au moins l'une des directions verticale et horizontale le long d'un trajet optique. La lentille est conçue pour diriger la lumière diffusée collectée vers le détecteur de lumière. Le dispositif de traitement et de calcul électrique est électriquement couplé à la source lumineuse et au détecteur de lumière. Le détecteur de lumière est conçu pour réduire au minimum le bruit de fond. La distance à l'objet est basée sur une différence de temps entre la transmission de l'impulsion de lumière et la détection de lumière diffusée.
