Title (EN) A SOLID STATE LIGHT DETECTION AND RANGING (LIDAR) SYSTEM
(FR) SYSTÈME DE DÉTECTION ET TÉLÉMÉTRIE DE LA DISTANCE PAR LA LUMIÈRE (LIDAR) À SEMI-CONDUCTEURS
Abstract:
(EN) A sensor system can comprise a light source configured to emit a light beam. Furthermore, the sensor system comprises one or more optical elements that is configured to homogenize the emitted light beam, which is directed toward a field of view (FOV) of the sensor system. Additionally, the sensor system comprises a detector with a plurality of photo detection devices, wherein each photo detection device of the plurality of photo detection devices is configured to receive at least a portion of photon energy of the light beam that is reflected back from one or more objects in the FOV of the sensor system and generate at least one electrical signal based on the received photon energy.
(FR) L'invention concerne un système de capteur pouvant comprendre une source de lumière conçue pour émettre un faisceau lumineux. En outre, le système de capteur comprend un ou plusieurs éléments optiques conçus pour homogénéiser le faisceau lumineux émis qui est dirigé vers un champ de vision (FOV) du système de capteur. De plus, le système de capteur comprend un détecteur comprenant une pluralité de dispositifs de photodétection, chaque dispositif de photodétection de la pluralité de dispositifs de photodétection étant conçu pour recevoir au moins une partie d'une énergie photonique du faisceau lumineux réfléchi par un ou plusieurs objets dans le FOV du système de capteur et générer au moins un signal électrique en fonction de l'énergie photonique reçue.
