Title
(EN) OPTICAL SWITCHING FOR TUNING DIRECTION OF LIDAR OUTPUT SIGNALS
(FR) COMMUTATION OPTIQUE PERMETTANT LA DIRECTION DE SYNTONISATION DE SIGNAUX DE SORTIE DE LIDAR
Abstract
(EN)
An optical system has a LIDAR chip that includes a switch configured to direct an outgoing LIDAR signal to one of multiple different alternate waveguides. The system also includes a redirection component configured to receive the outgoing LIDAR signal from any one of the alternate waveguides. The redirection component is also configured to redirect the received outgoing LIDAR signal such that a direction that the outgoing LIDAR signal travels away from the redirection component changes in response to changes in the alternate waveguide to which the optical switch directs the outgoing LIDAR signal.
(FR)
L'invention concerne un système optique comportant une puce de LIDAR qui contient un commutateur conçu pour diriger un signal LIDAR sortant vers l'un des guides d'ondes parmi de multiples guides d'ondes alternatifs différents. Le système comprend également un composant de redirection, conçu pour recevoir le signal LIDAR sortant à partir de l'un quelconque des guides d'ondes alternatifs. Le composant de redirection est également conçu pour rediriger le signal LIDAR sortant reçu, de sorte qu'une direction dans laquelle le signal LIDAR sortant s'éloigne du composant de redirection varie en réponse à des variations dans le guide d'onde alternatif vers lequel le commutateur optique dirige le signal LIDAR sortant.
