    Abstract: In one embodiment, a lidar system includes a light source configured to emit multiple optical signals directed into a field of regard of the lidar system. The optical signals include a first optical signal and a second optical signal, where the second optical signal is emitted a particular time interval after the first optical signal is emitted. The lidar system also includes a receiver configured to detect a received optical signal that includes a portion of the emitted first or second optical signal that is scattered by a target located a distance from the lidar system. The received optical signal is detected after the second optical signal is emitted. The receiver includes a first detector configured to detect a first portion of the received optical signal and a second detector configured to detect a second portion of the received optical signal.

    Abstract: In one embodiment, a lidar system includes a light source configured to emit a ranging pulse of light that is directed into a field of regard of the lidar system. The lidar system also includes a fiber-optic splitter configured to split off a portion of the ranging pulse of light to produce a trigger pulse of light that is directed to a receiver of the lidar system. The receiver is configured to detect, at a first time, at least a portion of the trigger pulse of light; and detect, at a second time subsequent to the first time, a portion of the ranging pulse of light scattered by a target located a distance from the lidar system. The lidar system further includes a processor configured to determine the distance from the lidar system to the target based at least in part on the first time and the second time.
