  • Automated lidar target simulation scanning systems and methods
    Patent number: 12174296
    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.
    Type: Grant
    Filed: February 16, 2021
    Date of Patent: December 24, 2024
    Assignee: KEYSIGHT TECHNOLOGIES, INC.

  • AUTOMATED LIDAR TARGET SIMULATION SCANNING SYSTEMS AND METHODS
    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.
