Title:
MULTI-LINE LASER RADAR
Document Type and Number:
WIPO Patent Application WO/2019/129259
Kind Code:
A1
Abstract:
Provided is a multi-line laser radar (20, 30), comprising a first radar assembly (201, 301), wherein the first radar assembly (201, 301) comprises n lasers (21, 311, 312), an optical collimating unit (22, 315), a scanning rotating mirror (23, 321) and one detector (24, 331), n being greater than 1; each of the lasers (21, 311, 312) is used for emitting a laser beam to the optical collimating unit (22, 315); the optical collimating unit (22, 315) is used for collimating n laser beams, and the n collimated laser beams are emitted to a target reflecting mirror of the scanning rotating mirror (23, 321); the scanning rotating mirror (23, 321) comprises m reflecting mirrors (3211, 3212) rotating around a rotation shaft (3213), and a rotation plane of the rotation shaft (3213) is perpendicular to an arrangement direction of the n collimated laser beams, m being greater than 1; the target reflecting mirror is used for reflecting the n received collimated laser beams to a detection region of the first radar assembly (201, 301); and the detector (24, 331) is used for receiving an echo signal of the n reflected laser beams in the detection region. According to the multi-line laser radar (20, 30), a multi-line laser radar structure of "multiple-emission and single-reception" is provided, so that the signal crosstalk between detectors is avoided, the working performance is improved, and the costs are reduced.
