Patent number: 11585901Abstract: According to one aspect, an optical transceiver includes a substrate and a laser fixed to a first surface of the substrate, the laser generating output light for transmission along a transmission axis into a region. An optical detection element is fixed to a second surface of the substrate opposite the first surface, the optical detection element receiving input light reflected from the region along a reception axis through an opening in the substrate between the first and second surfaces of the substrate, the transmission axis and the reception axis being substantially parallel.Type: GrantFiled: August 20, 2018Date of Patent: February 21, 2023Assignee: VEONEER US, LLCInventors: Peter Hansson, Emil Hallstig, Bernard De Mersseman

Patent number: 11480659Abstract: A detection system for a vehicle in an environment includes at least one reflective member having a rotational axis and a plurality of reflective sides. Each of the reflective sides slopes towards the rotational axis at a slope angle different than the slope angle of at least one of the others of the reflective sides. The system includes a plurality of LiDAR systems with at least one light transmitter and at least one light receiver, each LiDAR system interacting with a different one of the reflective sides to scan the environment.Type: GrantFiled: August 20, 2018Date of Patent: October 25, 2022Assignee: Veoneer US, LLCInventors: Peter Hansson, Emil Hallstig, Bernard DeMersseman, Mauritz Andersson

Patent number: 11194022Abstract: A detection system for a vehicle in an environment has a reflective member positioned along an x-y plane for rotation around a rotational axis orthogonal to the x-y plane. The reflective member has a plurality of reflective sides, each of the reflective sides sloping towards the rotational axis at a slope angle different than the slope angle of at least one of the others of the reflective sides. At least one detector is positioned offset from the rotational axis and the x-y plane, an active side of the plurality of reflective sides positioned to provide a field of view between the detector and the environment. An actuator is configured to rotate the reflective member around the rotational axis to change the active reflective side to a different one of the plurality of reflective sides.Type: GrantFiled: June 1, 2018Date of Patent: December 7, 2021Assignee: Veoneer US, Inc.Inventors: Bernard de Mersseman, Peter Hansson, Emil Hällstig

Patent number: 11073604Abstract: A LiDAR detection system includes optical sources generating a plurality of output optical signals disposed along a first direction. A modulation circuit applies an output signal from a signal generator to the optical sources to modulate the output optical signals such that the output optical signals are envelope-modulated output optical signals having frequency-modulated modulation envelopes. A scanning device scans the output optical signals into a region over a second direction. A receiver comprising a two-dimensional array of optical detectors receives return optical signals and generates receive signals indicative of the return optical signals. The return optical signals impinge on a mask between the region and the array, the mask comprising a plurality of apertures aligned with a first dimension of the array. The receive signals are generated for a set of detectors in the array disposed along the first dimension of the array and aligned with the mask apertures.Type: GrantFiled: March 5, 2020Date of Patent: July 27, 2021Assignee: VEONEER US, INC.Inventors: Emil Hallstig, Jonas Wihlbeck, Peter Hansson, Bernard de Mersseman, Kenneth Puglia

Publication number: 20200081129Abstract: A detection system for a vehicle in an environment includes a reflective member configured to rotate about a first axis, the reflective member having a plurality of reflective sides. The detection system has a LiDAR system with at least one light transmitter and at least one light receiver. A wedge mirror deflects light between the LiDAR system and the reflective member to change the field of view of the LiDAR system in an elevation direction and in an azimuth direction. The reflective member is positioned such that rotation of the reflective member changes the field of view of the LiDAR system in an azimuth direction.Type: ApplicationFiled: December 21, 2018Publication date: March 12, 2020Inventors: Bernard de Mersseman, Peter Hansson, Emil Hallstig, Olov Von Hofsten
