Abstract: Abstract: The invention relates to a test system for testing a LIDAR device (1), comprising a controller (5) for generating LIDAR information relating to a simulated LIDAR object based on a real object to be reproduced for a test process, wherein the LIDAR information includes at least one item of two-dimensional contour information and an item of depth information relating to a virtual distance of the simulated LIDAR object; comprising a LIDAR image generation device (6) for generating the simulated LIDAR object based on the LIDAR information, and comprising a LIDAR projection device (7) for projecting the simulated LIDAR object (9) onto a projection surface (8). The depth information is determined on the basis of a time component between the projection surface (8) and the LIDAR device (1) to be tested, which is defined by the controller (5).
