Abstract

一种激光雷达(10)及自动驾驶设备(1)，包括：旋转设备，包括第一旋转部(100)以及第二旋转部(200)，第一旋转部(100)与第二旋转部(200)之间可产生绕旋转轴线(20)的相互转动；激光收发组件(300)与第一旋转部(100)连接，且配置成可发射出射激光以及接收反射激光；反射组件(400)与第二旋转部(200)连接，反射组件(400)包括至少两个反射镜(410)，各反射镜(410)绕旋转轴线(20)布置，且至少两个反射镜(410)与垂直于旋转轴线(20)的平面的夹角不同。该方案中由被探测物反射回的反射激光能够由同一个反射镜反射回，使得同一个反射镜既能够反射出射激光，又能够反射反射激光。该方案具有至少两个布置角度不同的反射镜，从而使得上述两个反射镜行程的视场为两个平面，增大了激光雷达的探测视场。
