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; a second optical signal emitted a first time period τ1 after the first optical signal; and a third optical signal emitted a second time period τ2 after the second optical signal, where τ2 is different from τ1. The lidar system also includes a receiver configured to detect a first input optical signal and a second input optical signal. The first and second input optical signals each include light from one of the emitted optical signals that is scattered by a target located a distance from the lidar system.
