Abstract: A LiDAR transmitter with optical power monitoring includes a laser array positioned in a first plane that generates optical beams that propagate along an optical path. A first projecting optical element positioned in the optical path projects the plurality of optical beams to overlap at a common point. A second projecting optical element projects light from the first projecting optical element in a direction of transmission. A directing optical element positioned at the common point in the optical path of the plurality of beams produces an illumination region with light from each of the plurality of beams in a second plane. A monitor generates a detected signal in response to the collected light. A controller generates the electrical signal in response to the detected signal that controls the laser to achieve a desired operation of the LiDAR system transmitter.

Abstract: A solid-state LIDAR transmitter includes a laser array comprising first and second laser pixels that each generate first and second sub-aperture beams. A first microlens focuses first and second sub-aperture beams generated by the first laser pixel and focuses first and second sub-aperture beams generated by the second laser pixel. A second microlens directs the first and second sub-aperture beams generated by the first pixel such that they overlap at a plane. A lens projects the first sub-aperture beam generated by the first laser pixel and the first sub-aperture beam generated by the second laser pixel with a different angle in the far field in order to achieve a desired spatial resolution of the LIDAR system.

Abstract: A LIDAR system includes an optical transmitter comprising a plurality of lasers, each illuminating a FOV in an illumination region. A transmitter controller has outputs connected to respective laser inputs. The transmitter controller generates electrical pulses at the outputs so that the lasers generate light in a desired pattern in the illumination region. An optical receiver has an input FOV in the illumination region and comprises a plurality of detectors, each having a FOV and being positioned to detect light over the illumination region; and a TOF measurement circuit that measures the TOF from the lasers to the detectors. The receiver calculates range information. An adaptive optical shutter positioned between the optical transmitter and the optical receiver has a transparent or reflected region FOV, where the optical shutter restricts illumination at the input of the optical receiver to a region which is smaller than the optical receiver FOV.

Abstract: A LiDAR receiver includes an optical element configured with an optical power that projects light rays received at an input to a region where the received light rays overlap. An apodized aperture in the region where the received light rays overlap is configured with an optical transmission profile that changes radially across the apodized aperture to provide a desired modulation of the overlapped received light rays. Detector optics positioned adjacent to the apodized aperture focuses the modulated light rays at a detector plane. A two-dimensional pixilated detector array is positioned at the detector plane. The detector optics and desired modulation are chosen so that a ratio of an intensity of modulated light rays on one pixel of the two-dimensional array of pixels to an intensity of modulated light rays on an adjacent pixel of the two-dimensional array of pixels is a desired value.

Abstract: A LIDAR system includes a plurality of lasers that generate an optical beam having a FOV. A plurality of detectors are positioned where a FOV of at least one of the plurality of optical beams generated by the plurality of lasers overlaps a FOV of at least two of the plurality of detectors. The lens system collimates and projects the optical beams generated by the plurality of lasers. An actuator is coupled to at least one of the plurality of lasers and the lens system to cause relative motion between the plurality of lasers and the lens system in a direction that is orthogonal to an optical axis of the lens system so as to cause relative motion between the FOVs of the optical beams generated by the plurality of lasers and the FOVs of the detectors.
