Title
(EN) Laser radar optical system
(ZH) 一种激光雷达光学系统
Abstract
(EN)
The utility model discloses a laser radar optical system. The laser radar optical system comprises a transmitting unit, a first reflecting unit, a second reflecting unit and a receiving unit. The transmitting unit, the first reflecting unit, the second reflecting unit and the receiving unit are sequentially arranged along a light propagation path; the emitting unit is used for emitting laser beams; the relative positions of the transmitting unit and the receiving unit are fixed; the first reflection unit comprises a first reflection surface, and the relative position relation between the first reflection surface and the emission unit is variable, so that the laser beam completes scanning in the first direction; the second reflection unit comprises a second reflection surface, and the relative position relation between the second reflection surface and the emission unit is variable, so that the laser beam completes scanning in the second direction; wherein the first direction and the second direction are crossed. The laser radar optical system provided by the utility model can achieve the purposes of enlarging a scanning area and simplifying a processing circuit.
