Title
(EN) DIFFERENTIAL ABSORPTION LIDAR FOR PROFILING TEMPERATURE
(FR) LIDAR À ABSORPTION DIFFÉRENTIELLE POUR PROFILAGE DE TEMPÉRATURE
Abstract
(EN)
A beam transmitter, a receiver, and a LIDAR, along with methods to operate each are provided. The beam transmitter comprises a first and a second transmission channel (201a, 201b), each transmission channel including a first online laser, a first offline laser, and a first laser transmission selection switch operable to toggle between including the first online laser signal and the first offline laser signal in a first transmission beam. The beam transmitter further includes at least one light redirection device operable to coalign the first transmission beam with the second transmission beam. The receiver comprises a first splitter (402a, 402b), a first filter (404a, 404b), a first detector channel (406a, 406b), a second splitter (408a, 408b), a second filter (410a, 410b), and a second detector channel (412a, 412b). The LIDAR includes the beam transmitter, the receiver, and a shared telescope.

L'invention concerne un émetteur de faisceau, un récepteur et un LIDAR, ainsi que des procédés pour faire fonctionner chacun d'entre eux. L'émetteur de faisceau comprend un premier et un second canal de transmission (201a, 201b), chaque canal de transmission comprenant un premier laser en ligne, un premier laser hors ligne, et un premier commutateur de sélection d'émission laser utilisable pour basculer entre l'inclusion du signal du premier laser en ligne et du signal du premier laser hors ligne dans un premier faisceau d'émission. L'émetteur de faisceau comprend en outre au moins un dispositif de redirection de lumière utilisable pour co-aligner le premier faisceau d'émission avec le second faisceau d'émission. Le récepteur comprend un premier séparateur (402a, 402b), un premier filtre (404a, 404b), un premier canal de détecteur (406a, 406b), un second séparateur (408a, 408b), un second filtre (410a,410b), et un second canal de détecteur (412a, 412b). Le LIDAR comprend l'émetteur de faisceau, le récepteur et un télescope partagé.
