Abstract
Object detection and distance measurement using a scanning device is provided. The beam deflection device for light detection and ranging (LiDAR) includes a base, permanent magnets, a maglev reflector attached to the permanent magnets, and control coils mounted on the base. The maglev reflector may be configured to levitate due to an electromagnetic interaction of the permanent magnets and the control coils, and the control coils may consist of horizontal (H)-control coils defining a position of the maglev reflector in a horizontal direction and vertical (V)-control coils defining a position of the maglev reflector in a vertical direction.
