MULTI-LINE LASER RADAR

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 is configured to reflect the received collimated n laser beams to a detection area of the first radar component. The detector is configured to receive echo signals of the reflected n laser beams in the detection area. This application provides a multi-line laser radar structure of "multiple transmit and single receive", so as to avoid a signal crosstalk between detectors, improve working performance, and reduce costs.
