    Abstract: A LIDAR system is disclosed. The system may include a laser light projection system that may simultaneously provide at least two laser light beams. The system may also include an optical system, including one or more deflectors to project the at least two laser light beams toward a field of view of the LIDAR system. Each of the laser light beams may have an energy density below an eye safe level. However, a total combined energy density of the laser light beams may exceed an eye safe level. The laser light beams may be projected from the deflector are spaced apart from one another by an angular spacing ranging from 2.5 mrad to 6 mrad.

    Abstract: A LIDAR system is disclosed. The LIDAR system may include at least one light source configured to project laser light toward a field of view of the LIDAR system, at least one sensor configured to detect laser light reflections from objects in the field of view of the LIDAR system, and at least one processor configured to perform operations. The processor may be configured to use the laser light reflections to generate point-cloud representations of an environment of the LIDAR system within the field of view of the LIDAR system, output navigational information based on the generated point-cloud representations to one or more processors associated with a vehicle on which the LIDAR system is mounted, and store at least some of the generated point-cloud representations in a cache memory to provide a point-cloud archive. The processor may further be configured to detect occurrence of a point-cloud archive output triggering event, in response to detection of the point-cloud archive output triggering event, collect from the cache memory two or more point clouds from the point-cloud archive that were generated within a predetermined period of time relative to the detected point-cloud archive output triggering event, and output the two or more point clouds collected from the cache memory.

    Abstract: A LIDAR system includes a light source configured to generate a plurality of laser beams arranged in a beam pattern, a rotatable deflector configured to rotate about a scanning axis, a beam rotator configured to cause rotation of the beam pattern of the plurality of laser beams relative to the scanning axis of the rotatable deflector and at least one sensor configured to receive, via the rotatable deflector and the beam rotator, laser light resulting from one or more of the plurality of laser beams reflected from at least one object in the field of view of the LIDAR system wherein the multibeam array is maintained at a substantially fixed orientation with respect to the optical axis.

    Abstract: A LIDAR system may have a laser emission unit configured to generate a plurality of laser beams. The LIDAR system may also have an optical system configured to transmit the plurality of laser beams from the laser emission unit to a common scanning unit. The common scanning unit may be configured to project the plurality of laser beams towards a first set of spaced apart locations of a field of view of the LIDAR system. The first set of spaced apart locations may be associated with a first plurality of parallel scan lines traversing the field of view. The common scanning unit may also be configured to simultaneously scan the field of view along the first plurality of scan lines by sequentially illuminating non-contiguous segments in a first set of non-contiguous segments of the field of view positioned along the first plurality of scan lines.

    Abstract: A LIDAR system has a laser emission unit configured to generate a plurality of laser beams. The system has a scanning unit configured to receive the plurality of laser beams. The common scanning unit projects the plurality of laser beams toward a field of view of the LIDAR system. The system has at least one processor. The processor is programmed to cause the scanning unit to scan the field of view of the LIDAR system by directing the plurality of beams along a first plurality of scan lines traversing the FOV. The processor is also programmed to displace the plurality of laser beams from a first set of locations associated with the first plurality of scan lines to a second set of locations associated with a second plurality of scan lines. Further, the processor is programmed to direct the plurality of laser beams along the second plurality of scan lines.
