Abstract
Various technologies described herein pertain to multiple beam, single mirror lidar. A multiple beam, single mirror lidar system can include a 2D MEMS mirror and a photonic integrated circuit. The photonic integrated circuit includes a plurality of lidar channels, each including a transmitter and a receiver. In the photonic integrated circuit, the lidar channels are directed at a common point on the 2D MEMS mirror. The lidar channels are oriented with relative offset angles. Thus, the lidar channels output beams that are directed at the common point on the 2D MEMS mirror and are oriented with relative offset angles.
