Title
(EN) A LEVER SYSTEM FOR DRIVING MIRRORS OF A LIDAR TRANSMITTER
(FR) UN SYSTÈME DE LEVIER POUR COMMANDER DES MIROIRS D'UN ÉMETTEUR LIDAR
Abstract
(EN)
A lever is used to rotate a microelectromechanical systems (MEMS) mirror. The lever can be used to provide more torque from a vertical comb drive. The MEMS mirror can be part of an array of micro mirrors used for beam steering a laser in a Light Detection and Ranging (LiDAR) system for an autonomous vehicle.
(FR)
L'invention concerne un levier qui est utilisé pour faire tourner un miroir de systèmes microélectromécaniques (MEMS). Le levier peut être utilisé pour fournir plus de couple à partir d'une commande verticale en peigne. Le miroir MEMS peut faire partie d'un réseau de micro-miroirs utilisés pour diriger un faisceau laser dans un Système de Détection de Lumière et de Télémétrie (LiDAR de l'anglais "Light Detection and Ranging") pour un véhicule autonome.
