1. An apparatus for automated positioning of an optical test module relative to a Lidar sensor during a target simulation test of the Lidar sensor, the apparatus comprising:
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 a Lidar sensor under test;
a vertical actuator configured to convey the test module platform relative to a 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 Lidar sensor 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.
