Title (EN) LIGHT-GUIDE-BASED LIDAR SYSTEM
(FR) SYSTÈME LIDAR À BASE DE CONDUITS DE LUMIÈRE
(DE) LICHTLEITER-BASIERTES LIDAR-SYSTEM
Abstract:
(EN) The present invention relates to a lidar system (1), comprising a beam source (2) configured to produce a scanning beam, a detector (3) configured to receive a reflection of the scanning beam, said reflection having been cast back to the lidar system (1) after the scanning beam was reflected in surroundings of the lidar system (1), a light guide bundle (4) which comprises at least one first light guide (5) and one second light guide (6), wherein the first light guide (5) is coupled to the beam source (2) at a first end of the first light guide (5) and the second light guide (6) is coupled to the detector (3) at a first end of the second light guide (6), and a sensor head (7), in which a second end of the first light guide (5) and a second end of the second light guide (6) are merged, wherein the sensor head (7) further has a deflection apparatus in order to steer the scanning beam guided by the first light guide (5) to the sensor head (7) in a changing direction during a scanning process.
(FR) L'invention concerne un système LIDAR (1) comprenant une source de rayonnement (2) conçue pour produire un faisceau de balayage, un détecteur (3) conçu pour recevoir une réflexion du faisceau de balayage, laquelle est renvoyée au système LIDAR (1) lorsque le faisceau de balayage a été réfléchi dans un environnement du système LIDAR (1), un faisceau de fibres optiques (4) qui comprend au moins un premier conduit de lumière (5) et un second conduit de lumière (6), le premier conduit de lumière (5) étant couplé, à une première extrémité du premier conduit de lumière (5), à la source de rayonnement (2), et le second conduit de lumière (6) étant couplé, à une première extrémité du second conduit de lumière (6), au détecteur (3), et une tête de capteur (7), dans laquelle une seconde extrémité du premier conduit de lumière (5) et une seconde extrémité du second conduit de lumière (6) sont réunies, la tête de capteur (7) comportant en outre un dispositif de déviation pour dévier dans une direction variable le faisceau de balayage, guidé jusqu'à la tête de capteur (7) par l'intermédiaire du premier conduit de lumière (5), pendant un processus de balayage.
(DE) Die vorliegende Erfindung betrifft ein LiDAR-System (1), umfassend eine Strahlquelle (2), welche dazu eingerichtet ist, einen Scanstrahl zu erzeugen, einen Detektor (3), welcher dazu eingerichtet ist, eine Reflektion des Scanstahls zu empfangen, welche zu dem LiDAR-System (1) zurückgeworfen wird, wenn der Scanstrahl in einer Umgebung des LiDAR-Systems (1) reflektiert wurde, ein Lichtleiterbündel (4), welches zumindest einen ersten Lichtleiter (5) und einen zweiten Lichtleiter (6) umfasst, wobei der erste Lichtleiter (5) an einem ersten Ende des ersten Lichtleiters (5) mit der Strahlquelle (2) gekoppelt ist und der zweite Lichtleiter (6) an einem ersten Ende des zweiten Lichtleiters (6) mit dem Detektor (3) gekoppelt ist, und einen Sensorkopf (7), in dem ein zweites Ende des ersten Lichtleiters (5) und ein zweites Ende des zweiten Lichtleiters (6) zusammengeführt werden, wobei der Sensorkopf (7) ferner einer Ablenkvorrichtung aufweist, um den über den ersten Lichtleiter (5) zu dem Sensorkopf (7) geführten Scanstrahl während eines Scanvorgangs in eine wechselnde Richtung zu lenken.
