  • Publication number: 20230132855
    Abstract: An apparatus for testing a Lidar sensor includes a Lidar sensor platform, a target board including at least one vertically elongate surface facing in a direction of the Lidar sensor platform, and a base unit configured to position the target board to obtain a desired reflective property of the target board relative to an incident light scan emitted by a Lidar sensor mounted to the Lidar sensor platform during a target emulation test of the Lidar sensor.

  • Publication number: 20220260714
    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.

  • Publication number: 20210373137
    Abstract: Systems and components for testing a light detection and ranging (LIDAR) device under test (DUT) are described. In one example, an ellipsoid is adapted to receive the LIDAR DUT at a first focal point, where light transmitted from the LIDAR DUT is incident on the second focal point. In another example a plurality of optical waveguides arranged in at least a portion of a circle, and the plurality of optical waveguides are adapted to receive light from the LIDAR DUT. In another example, a LIDAR distance simulator is adapted to receive an optical input, and includes optical switches that are selectively connected to one of a plurality of optical delay devices to an input of the one of a plurality of optical input channels. Illustrative delay elements may be realized through optical delay elements or a combination of optical and electrical delay elements.
