COAXIAL SETUP FOR LIGHT DETECTION AND RANGING, LIDAR, MEASUREMENTS

摘要

A LIDAR system (100) for ranging an object (110) using primary light and secondary light reflected at the object (110), includes a laser (200), arranged to emit the primary light along a transmit beam (210) towards a scanning element (800) of the LIDAR system, wherein at least a part of the transmit beam adjacent to the scanning element defines a center line (300), a detector (400), arranged to detect the secondary light along a receive beam (500), wherein the receive beam includes a first part (510) aligned with the center line and a second part (520) having an inclination (530) with respect to the center line (300), wherein the second part (520) of the receive beam is in-between the first part of the receive beam (520) and the detector (400), and a segmented lens (600), positioned on the center line (300) in-between the first part of the receive beam (510) and the second part (520) of the receive beam, the segmented lens (600) including a transmit lens segment (610) associated with the transmit beam and a receive lens segment (620) associated with the receive beam, wherein the receive lens segment (620) is designed to focus the receive beam onto the detector.
