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), a digital micromirror device (6) comprising a matrix of mirrors (7), a lidar detector (8) and a further photo detector (9), and an electronic processing unit (19). Each mirror (7) of the digital micromirror device (6) is controllable by said electronic processing unit (19) to change at least between a first position where light entering the lidar imaging apparatus (30) through said lens objective (11) is directed on said lidar detector (8), and a second position where light entering the lidar imaging apparatus (30) through said lens objective (11) is directed on said further photo detector (9). Said 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), and to perform compressive sensing processing on the signal provided by said further photo detector (9) .
