Abstract[English]
The disclosed LiDAR systems and methods are for object detection. The LiDAR method comprising: i) transmitting a light signal x (t) towards a region of interest (ROI); ii) receiving a reflected light signal and ambient noise signal, the reflected light signal including reflected light pulses reflected from at least one object in the ROI and the ambient noise signal including light signals that are not generated by the light source; iii) detecting one or more photons in the reflected light signal and/or the ambient noise signal and generating a SPAD output signal; iv) converting the SPAD output signal to a digital signal; v) determining a location of the at least one object based on the digital signal; and vi) varying a diameter of an opening defined by the tunable aperture in accordance with the ambient noise signal and operational parameters associated with the LIDAR system.[French]
Les procédés et systèmes LiDAR de l'invention sont destinés à la détection d'objets. Le procédé LiDAR consiste à : i) transmettre un signal lumineux x (t) vers une région d'intérêt (ROI) ; ii) recevoir un signal lumineux réfléchi et un signal de bruit ambiant, le signal lumineux réfléchi comprenant des impulsions lumineuses réfléchies réfléchies par au moins un objet dans la ROI et le signal de bruit ambiant comprenant des signaux lumineux qui ne sont pas générés par la source lumineuse ; iii) détecter un ou plusieurs photons dans le signal lumineux réfléchi et/ou le signal de bruit ambiant et générer un signal de sortie SPAD ; iv) convertir le signal de sortie SPAD en un signal numérique ; v) déterminer un emplacement du ou des objets sur la base du signal numérique ; et vi) faire varier un diamètre d'une ouverture définie par l'ouverture accordable en fonction du signal de bruit ambiant et des paramètres opérationnels associés au système LIDAR.
