Abstract

L'invention concerne un module de détection de profondeur de TOF (600) et un procédé de génération d'image. Le module de détection de profondeur de TOF (600) comprend : une source de lumière laser (610), un élément optique (620), un diviseur de faisceau (630), une unité de réception (640) et une unité de commande (650), l'élément optique (620) étant disposé dans la direction dans laquelle la source de lumière laser (610) émet un faisceau. La source de lumière laser (610) sert à générer un faisceau laser ; l'élément optique (620) sert à commander la direction du faisceau laser, de façon à obtenir un premier faisceau sortant et un deuxième faisceau sortant ; le diviseur de faisceau (630) sert à propager, vers différentes régions de l'unité de réception (640), un troisième faisceau réfléchi obtenu par une réflexion du premier faisceau sortant par un objet cible et un quatrième faisceau réfléchi obtenu par une réflexion du deuxième faisceau sortant par l'objet cible. La perte de chaleur du module de capteurs de profondeur de TOF (600) est réduite.
