Publication number: 20240036180Abstract: A lidar test system includes a lensed fiber collector for receiving light pulses generated by a lidar sensor. A splitter is configured to split the light pulses received from the lensed fiber collector. A first optical fiber having a first length receives one of the split light pulses. A second optical fiber having a second length also receives one of the split light pulses. The second length of the second optical fiber is longer than the first length of the first optical fiber. A switch is configured to select light transmitted through one of the optical fibers to an optical output. A variable optical attenuator (“VOA”) is configured to regulate the intensity of the light received from the switch. The lidar test system also includes a diffuser target positioned to receive light from the VOA which may be imaged by a focal plane array of the lidar assembly.Type: ApplicationFiled: July 31, 2023Publication date: February 1, 2024Applicant: Continental Autonomous Mobility US, LLCInventors: Nan Luo, Barton M.

Publication number: 20230004160Abstract: A vehicular collision avoidance system comprising a system controller, pulsed laser transmitter, a number of independent ladar sensor units, a cabling infrastructure, internal memory, a scene processor, and a data communications port is presented herein. The described invention is capable of developing a 3-D scene, and object data for targets within the scene, from multiple ladar sensor units coupled to centralized LADAR-based Collision Avoidance System (CAS). Key LADAR elements are embedded within standard headlamp and taillight assemblies. Articulating LADAR sensors cover terrain coming into view around a curve, at the crest of a hill, or at the bottom of a dip. A central laser transmitter may be split into multiple optical outputs and guided through fibers to illuminate portions of the 360° field of view surrounding the vehicle. These fibers may also serve as amplifiers to increase the optical intensity provided by a single master laser.Type: ApplicationFiled: September 9, 2022Publication date: January 5, 2023Applicant: Continental Autonomous Mobility US, LLCInventors: Patrick Gilliland, Roger Stettner, Laurent Heuhebaert, Barton M Goldstein

Publication number: 20190317196Abstract: An apparatus for reducing crosstalk between cathodes of detector diodes of an imager detector array includes a capacitor and voltage switch coupled into a detector bias network to virtually isolate a detector diode from a common cathode power plane while simultaneously ‘powering’ the diode for image acquisition, e.g., photo current detection. A method includes a timing sequence wherein during non-acquisition time intervals, the capacitor is charged through the voltage switch by turning the switch on to allow charge to flow into the capacitor from a common supply plane. The method further includes disconnecting the capacitor before an acquisition timer interval such that during the acquisition time interval, the current through the detector diode, caused by incident flux, comes from the capacitor and not from the common cathode power plane.Type: ApplicationFiled: April 17, 2019Publication date: October 17, 2019Applicant: Continental Automotive Systems, Inc.Inventors: Martin Denham, Patrick B.
