Patent number: 11947039Abstract: A light detection and ranging (LiDAR) system includes light emitters that emit beams of light of substantially equal intensities. The light emitters form a beam polarization pattern with beams having varying polarizations. The LiDAR system also will include a receiver to receive light reflected from the object. An analyzer will determine characteristic differences between the beam polarization pattern of the beams emitted toward the object and an intensity pattern of the light reflected from the object, determine a reflection position that is associated with the light reflected from the object, and use the determined characteristic differences to determine whether the reflection position is a position of the object or a position of a ghost.Type: GrantFiled: May 19, 2022Date of Patent: April 2, 2024Assignee: LG INNOTEK CO., LTD.Inventors: Gary W. Kamerman, Christopher John Trowbridge, Viorel C. Negoita

Publication number: 20210011162Abstract: A light detection and ranging (LiDAR) system includes a light emitter and a light detector comprising a photodetector. The light detector is configured to receive and detect one or more characteristics of light emitted by the light emitter. The system also includes a polarization filter that is configured to limit polarization of light that is received by the light detector to a single polarization, and thus filter noise and/or certain retroreflected light from reaching the light detector.Type: ApplicationFiled: July 11, 2019Publication date: January 14, 2021Inventors: Gary W. Kamerman, Christopher John Trowbridge, Viorel C. Negoita

Patent number: 9690107Abstract: A device for wavelength coupling of laser beams (2a, . . . 2n) with different wavelengths (?1, . . . ?n), comprising: at least one laser source for generating a plurality of laser beams (2a, . . . , 2n), and an overlapping device for spatial overlapping of the plurality of laser beams (2a, . . . , 2n) for forming an overlapped laser beam with a plurality of wavelengths (?1 . . . ?n). The device has a feedback device arranged between the laser source and the overlapping device for feeding a radiation proportion of the laser beams (2a, . . . , 2n) to be overlapped back to the laser source, the feedback device comprising a partially reflecting angle-dispersive optical element, in particular a partially reflecting diffraction grating. The overlapping device may, for example, be configured as a transmitting or reflecting diffraction grating whose optical properties are adapted to the optical properties of the partially reflecting diffraction grating to overlap the laser beams (2a, . . .Type: GrantFiled: March 15, 2013Date of Patent: June 27, 2017Assignee: TRUMPF LASER GMBHInventors: Viorel C.

Patent number: 7936799Abstract: A laser system includes at least two sources configured to provide at least two spatially separated laser beams, and a mount configured to mount the at least two sources along an arc, the arc defining an angular coordinate and a radial coordinate, wherein an axial coordinate is orthogonal to the angular coordinate and the radial coordinate, and the spatially separated laser beams are separated in the axial coordinate. The mount is further configured to mount the at least two sources providing thereby an offset of the laser beams in the axial coordinate such that the laser beams interleave in the axial direction at a center region of the arc.Type: GrantFiled: October 27, 2008Date of Patent: May 3, 2011Assignee: Trumpf Photonics Inc.Inventors: Ulrich Bonna, Martin Liermann, Viorel C.
