LIDAR TEST SYSTEMS

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.
