  • Patent number: 11686818
    Abstract: A LiDAR system includes a first optical lens, and one or more first optoelectronic packages spaced apart from the first optical lens along the optical axis of the first optical lens. Each respective first optoelectronic package includes a first plurality of optoelectronic components positioned on the respective first optoelectronic package such that a surface of each respective optoelectronic component lies substantially on the first surface of best focus. The LiDAR system further includes a second optical lens, and one or more second optoelectronic packages spaced apart from the second optical lens along the optical axis of the second optical lens. Each respective second optoelectronic package includes a second plurality of optoelectronic components positioned on the respective second optoelectronic package such that a surface of each respective optoelectronic component lies substantially on the second surface of best focus.

  • Patent number: 11150348
    Abstract: A LiDAR system includes one or more light sources configured to emit a set of light pulses in a temporal sequence with randomized temporal spacings between adjacent light pulses, one or more detectors configured to receive a set of return light pulses, and a processor configured to: determine a time of flight for each return light pulse of the set of return light pulses; and obtain a point cloud based on the times of flight of the set of return light pulses. Each point corresponds to a respective return light pulse. The processor is further configured to, for each respective point of the set of points in the point cloud: analyze spatial and temporal relationships between the respective point and a set of neighboring points in the set of points; and evaluate a quality factor for the respective point based on the spatial and temporal relationships.

  • Publication number: 20210302543
    Abstract: A LiDAR sensor includes a first lens, a first laser source configured to emit a plurality of first light pulses to be collimated by the first lens, a flood illumination source configured to emit a plurality of second light pulses as diverging light rays, a second lens configured to receive and focus (i) a portion of any one of the plurality of first light pulses and (ii) a portion of any one of the plurality of second light pulses that are reflected off of the one or more objects, a detector configured to detect (i) the portion of any one of the plurality of first light pulses and (ii) the portion of any one of the plurality of second light pulses, and a processor configured to construct a three-dimensional image of the one or more objects based on the detected portions of first light pulses and second light pulses.
