COAXIAL SETUP FOR LIGHT DETECTION AND RANGING, LIDAR, MEASUREMENTS

摘要

A LIDAR system for ranging an object using primary and secondary light reflected at the object, includes a laser, arranged to emit the primary light along a transmit beam towards a scanning element of the system, wherein at least a part of the transmit beam adjacent to the scanning element defines a center line, a detector, arranged to detect the secondary light along a receive beam, wherein the receive beam includes a first part aligned with the center line and a second part having an inclination with respect to the center line, wherein the second part of the receive beam is in-between the first part and the detector, and a segmented lens, positioned on the center line in-between the first part of the receive beam and the second part of the receive beam, wherein the receive lens segment is designed to focus the receive beam onto the detector.
