Abstract: The present application discloses a method and a device for controlling a micro galvanometer of a solid-state LiDAR, and a solid-state LiDAR. The method includes acquiring a vertical angle range of a field of view scanned by the solid-state LiDAR, determining a first vertical angle of the field of view and a second vertical angle of the field of view corresponding to a preset ROI region of the solid-state LiDAR, reducing a slow axis scanning speed of the micro galvanometer to a first preset speed when it is monitored that the micro galvanometer scans the first vertical angle of the field of view, and adjusting the slow axis scanning speed of the micro galvanometer to a second preset speed when it is monitored that the micro galvanometer scans the second vertical angle of the field of view.

Abstract: The present disclosure provides a galvanometer motor, including a stator, a rotor, and a sensor board. The stator includes a housing and a drive coil mounted inside the housing. The rotor includes a rotating shaft and a galvanometer lens. A pair of radially magnetized magnetic poles are at the middle of the rotating shaft, two ends of the rotating shaft are rotatably mounted inside the housing, and one end of the rotating shaft extends outside the housing and is connected to the galvanometer lens. The sensor board is fixed on an inner wall of the housing and is at one end of the housing farther away from the galvanometer lens. The sensor board is mounted with one or more magnetic sensors configured to sense a magnetic field signal generated by the pair of magnetic poles, to obtain absolute positions of the rotating shaft and the galvanometer lens.

Abstract: This application discloses a galvanometer and a LiDAR. The galvanometer includes a first shaft and a second shaft. A first shaft drive voltage is used to control the galvanometer to vibrate around the first shaft, a second shaft drive voltage is used to control the galvanometer to vibrate around the second shaft, and the first shaft drive voltage and the second shaft drive voltage are superimposed to drive the galvanometer. There are N working intervals in a second shaft drive period, and in the N working intervals, the second shaft drive voltage and the first shaft drive voltage jointly drive the galvanometer to form N scanning tracks. The N scanning tracks do not coincide and N is a positive integer.
