WIDE FIELD-OF-VIEW LIDAR OPTICAL ASSEMBLY AND SYSTEM

A lidar system (10) includes a laser-source (18) configured to emit a plurality of laser-beams (20), and a single movable-mirror (22) positioned to reflect the plurality of laser-beams (20) from the laser-source (18). The movable-mirror (22) is operable to pivot about a single rotation-axis (24), Th...

Beschreibung
Zusammenfassung:	A lidar system (10) includes a laser-source (18) configured to emit a plurality of laser-beams (20), and a single movable-mirror (22) positioned to reflect the plurality of laser-beams (20) from the laser-source (18). The movable-mirror (22) is operable to pivot about a single rotation-axis (24), The system (10) includes a first-optical wedge (26) configured to direct at least a first-laser-beam (28) of the plurality of laser-beams (20) reflected by the movable-mirror (22) in a first-direction (30) with respect to a bore-axis (32) of the system (10), and a second-optical-wedge (34) configured to direct at least a second-laser-beam (36) of the plurality of laser-beams (20) reflected by the movable-mirror (22) in a second-direction (38) with respect to the bore-axis (32) of the system (10), where the second-direction (38) characterized as different from the first-direction (30). The system (10) also includes a first-shutter (40) interposed between the first-optical-wedge (26) and the movable-mirror (22), and a second-shutter (42) interposed between the second-optical-wedge (34) and the movable-mirror (22). The first-shutter (40) and the second-shutter (42) are independently and alternately operable to a transmissive-state and a blocking-state.
