Abstract

L'invention concerne un système de détection et de télémétrie de lumière. Le système comprend un miroir galvanométrique; un dispositif de direction de lumière à facettes multiples; et un dispositif de commande comprenant un ou plusieurs processeurs, une mémoire et des instructions exécutables par processeur stockées en mémoire. Les instructions exécutables par processeur comprennent des instructions pour: recevoir un premier profil de mouvement du miroir galvanométrique du système de balayage LiDAR; recevoir des données d'étalonnage du dispositif de direction de lumière à facettes multiples du système de balayage LiDAR; générer un second profil de mouvement du miroir galvanométrique sur la base des données d'étalonnage et du premier profil de mouvement; et fournir un ou plusieurs signaux de commande pour ajuster le mouvement du miroir galvanométrique sur la base du second profil de mouvement.
