Lidar system
First Claim
1. A lidar system comprising:
- a light source configured to emit pulses of light as an output beam;
an overlap mirror comprising a reflecting surface with an aperture through which the output beam passes;
a scanner comprising one or more mirrors driven by a galvanometer scanner, a resonant scanner, a microelectromechanical systems (MEMS) device, or a voice coil motor, the one or more mirrors being configured to direct the output beam toward a light source field of view within a field of regard and to move the light source field of view to different locations within the field of regard, the one or more mirrors being further configured to receive reflected or scattered portions of the output beam as an input beam and to direct the input beam toward the reflecting surface of the overlap mirror; and
a receiver configured to receive the input beam from the reflecting surface of the overlap mirror, the receiver having a receiver field of view that moves synchronously with, and at least partially overlaps, the light source field of view, whereinthe light source field of view and the receiver field of view are scanned along a scanning direction; and
the receiver field of view is offset from the light source field of view in a direction opposite the scanning direction.

Abstract
A lidar system having a light source to emit an output beam and an overlap mirror having a reflecting surface with an aperture through which the output beam passes. The lidar system may include mirrors driven by a galvanometer scanner, a resonant scanner, a microelectromechanical systems device, or a voice coil motor. The mirrors may direct the output beam toward a light source field of view (FOV) and may move the light source FOV to different locations within a field of regard. The mirrors may receive reflected portions of the output beam as an input beam and direct the input beam toward the reflecting surface of the overlap mirror. The lidar system may include a receiver to receive the input beam from the reflecting surface of the overlap mirror. The receiver may have a receiver FOV that moves synchronously with, and at least partially overlaps, the light source FOV.
