Title
(EN) Laser radar optical system and scanning method
(ZH) 一种激光雷达光学系统及扫描方法
Abstract
(EN)
The invention discloses a laser radar optical system and a scanning method. The laser radar optical system includes an emitting unit, a first reflecting unit, a second reflecting unit and a receivingunit. The emitting unit, the first reflecting unit, the second reflecting unit and the receiving unit are arranged in sequence along the propagation path of light. The emitting unit is used for emitting a laser beam. The relative positions of the emitting unit and the receiving unit are fixed. The first reflecting unit includes a first reflecting surface, and the relative position relation betweenthe first reflecting surface and the emitting unit is changeable, so that the laser beam can complete scanning in a first direction. The second reflecting unit includes a second reflecting surface, and the relative position relation between the second reflecting surface and the emitting unit is changeable, so that the laser beam can complete scanning in a second direction. The first direction andthe second direction intersect with each other. The laser radar optical system provided by the invention can realize the purposes of enlarging the scanning area and simplifying the processing circuit.
