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. 在一个实施例中，激光雷达系统包括光源，该光源被配置为发射引导到激光雷达系统的能视域的多个光信号。光信号包括第一光信号和第二光信号，其中在发射第一光信号之后的特定时间间隔发射第二光信号。该激光雷达系统还包括接收器，该接收器被配置为检测接收光信号，该接收光信号包括发射的第一或第二光信号的由位于距激光雷达系统一定距离的目标散射的
