Abstract: A beam scanning apparatus with arrayed rotating mirrors is provided. The beam scanning apparatus includes a motor, a worm, a wormgear, a mounting rack, and a rotating mirror, where the worm and the wormgear are located on the mounting rack, and engage with each other by using a gear for a linkage connection; the rotating mirror is located in the mounting rack, and is coaxially connected to the wormgear; and the motor is configured to drive the worm to rotate, to drive the wormgear and the rotating mirror to rotate coaxially. The rotating mirror may be replaced with another rotating mirror with a different structure and a different optical parameter, to adjust output performance of the beam scanning apparatus, thereby improving extensibility.

Abstract: A multi-line laser radar includes a first radar component, where the first radar component includes n lasers, an optical collimating unit, a scanning rotating mirror, and a detector, where n is greater than 1. Each laser is configured to emit one laser beam to the optical collimating unit. The optical collimating unit is configured to collimate n laser beams, where the collimated n laser beams are incident on a target reflector of the scanning rotating mirror. The scanning rotating mirror includes m reflectors rotating around a rotation axis, where a rotation plane of the rotation axis is perpendicular to an arrangement direction of the collimated n laser beams, and m is greater than 1. The target reflector reflects the received collimated n laser beams to a detection area of the first radar component. The detector receives echo signals of the reflected n laser beams in the detection area.
