Title (EN) LIDAR SYSTEM
(FR) SYSTÈME LIDAR
(DE) LIDARSYSTEM
Abstract:
(EN) The present invention relates to a lidar system (1) comprising a first light source (2) for emitting first light (4), which is amplitude-modulated with a first frequency, a second light source (3) for emitting second light (5), which is amplitude-modulated with a second frequency different from the first frequency, and a receiving device (6) for detecting a reflection (7), on which the first light (4) and the second light (5) are superimposed.
(FR) La présente invention concerne un système LIDAR (1) comprenant une première source de lumière (2) pour l'émission d'une première lumière (4), qui est modulée en amplitude avec une première fréquence, une deuxième source de lumière (3) pour l'émission d'une deuxième lumière (5), qui est modulée en amplitude avec une deuxième fréquence différente de la première fréquence, et un dispositif de réception (6) pour la détection d'une réflexion (7) dans laquelle la première lumière (4) et la deuxième lumière (5) se superposent.
(DE) Die vorliegende Erfindung betrifft ein Lidarsystem (1) umfassend eine erste Lichtquelle (2) zum Aussenden von erstem Licht (4), das mit einer ersten Frequenz amplitudenmoduliert ist, eine zweite Lichtquelle (3) zum Aussenden von zweitem Licht (5), das mit einer von der ersten Frequenz unterschiedlichen zweiten Frequenz amplitudenmoduliert ist, und eine Empfangsvorrichtung (6) zum Erkennen einer Reflexion (7), an der sich das erste Licht (4) und das zweite Licht (5) überlagern.
