Abstract:
A light detection and ranging (LIDAR) device that scans through a scanning zone while emitting light pulses and receives reflected signals corresponding to the light pulses is disclosed. The LIDAR device scans the scanning zone by directing light toward a rotating mirror to direct the light pulses through the scanning zone. The rotating mirror is driven by a conductive coil in the presence of a magnetic field. The conductive coil is coupled to the rotating mirror and arranged in a plane perpendicular to the axis of rotation of the mirror. The axis of rotation of the mirror is oriented substantially parallel to a reflective surface of the mirror and passes between the reflective surface and the conductive coil.
