Abstract

An apparatus automatically positions an optical test module relative to a Lidar sensor during a target simulation test of the Lidar sensor. The apparatus includes a sensor platform configured to support a Lidar sensor, and a test module platform configured to support an optical test module such that an optical window of the optical test module faces in a direction towards the Lidar sensor supported by the sensor platform. The apparatus further includes a vertical actuator configured to convey the test module platform relative to the sensor platform such that the optical test module moves in a vertical arc while the optical window of the optical test module faces the Lidar sensor, a horizontal actuator configured to convey the test module platform relative to the sensor platform such that the optical test module moves in a horizontal arc while the optical window of the optical test module faces the Lidar sensor, and a rotational actuator configured to rotate the optical test module about a vertical axis of the test module platform.
