  • Patent number: 11360218
    Abstract: A lidar system includes a laser-source configured to emit laser-beams, and a single movable-mirror positioned to reflect the laser-beams from the laser-source. The movable-mirror is operable to pivot about a single rotation-axis. The system includes a first-optical wedge configured to direct at least a first-laser-beam reflected by the movable-mirror in a first-direction with respect to a bore-axis of the system, and a second-optical-wedge configured to direct at least a second-laser-beam reflected by the movable-mirror in a second-direction with respect to the bore-axis, where the second-direction is different from the first-direction. The system also includes a first-shutter interposed between the first-optical-wedge and the movable-mirror, and a second-shutter interposed between the second-optical-wedge and the movable-mirror.
