Abstract

A lidar imaging apparatus (30) for a motor vehicle comprises an emitting section (23) adapted to emit a pulsed light beam (3) and to change the direction of the light beam (3) in two dimensions perpendicularly to the light beam (3), a receiving section (24) having a lens objective (11) and a lidar detector (8), and an electronic processing unit (19). Light entering the lidar imaging apparatus (30) through said lens objective (11) is directed on said lidar detector (8). The electronic processing unit (19) is adapted to determine the time-of-flight of a laser pulse from said emitting section (23) to said lidar detector (8). The receiving section (24) comprises a beam splitter (60) arranged in the light path from said lens objective (11) to said lidar detector (8), and a further photo detector (61). The beam splitter (60) is adapted to split off a part of the light beam from said lens objective (11) and to direct the split-off part of said light beam to said further photo detector (61).
