摘要： Embodiments discussed herein refer to an integrated mirror motor galvanometer. The integrated mirror motor galvanometer repurposes a rotor of a motor to include at least one mirror face that redirects the light pulses interfacing therewith. This way, when the rotor oscillates along its range of rotation, the at least one mirror face also oscillates.

摘要： A rotatable optical reflector device of a Light Detection and Ranging (LiDAR) scanning system used in a motor vehicle is disclosed. The rotatable optical reflector device comprises a glass-based optical reflector including a plurality of reflective surfaces and a flange. The rotatable optical reflector device further comprises a metal-based motor rotor body at least partially disposed in an inner opening of the glass-based optical reflector. The rotatable optical reflector device further comprises an elastomer piece having a first surface and a second surface. The first surface of the elastomer piece is in contact with a second mounting surface of the flange. The rotatable optical reflector device further comprises a clamping mechanism compressing the elastomer piece at the second surface of the elastomer piece, wherein movement of the metal-based motor rotor body causes the glass-based optical reflector to optically scan light in a field-of-view of the LiDAR scanning system.

摘要： An embodiment of a motorized optical scanner of a Light Detection and Ranging (LiDAR) system used in a motor vehicle is provided. The scanner includes a reflective piece including a substrate and a reflective surface. The scanner further includes a first shaft and a second shaft attached to a first end and a second end of the substrate respectively. The first end and the second end are opposite ends of the substrate along a longitudinal direction of the substrate. The scanner further includes a first bearing and a second bearing coupled to the first shaft and the second shaft respectively. The first bearing and the second bearing are substantially concentric. Movement of the second shaft causes the reflective surface to optically transmit one or more light beams to a field-of-view.
