1. A multiple beam, single mirror lidar system, comprising:
a two-dimensional (2D) micro-electro-mechanical systems (MEMS) mirror; and
a photonic integrated circuit, comprising:
a first lidar channel, the first lidar channel comprises a first transmitter and a first receiver; and
a second lidar channel, the second lidar channel comprises a second transmitter and a second receiver;
wherein the first lidar channel and the second lidar channel are directed at a common point on the 2D MEMS mirror and are oriented with a relative offset angle.
