Abstract

一种激光雷达(10)及具有激光雷达(10)的设备，激光雷达(10)包括探测组件(110)，探测组件(110)包括第一激光发射装置(1111)，第二激光发射装置(1112)，及激光接收装置(112)，位于第一激光发射装置(1111)与第二激光发射装置(1112)之间，以接收经第一探测区域反射的第一激光束、以及经第二探测区域反射的第二激光束；其中，第一激光发射装置(1111)的发射功率大于第二激光发射装置(1112)的发射功率。通过将激光雷达(10)设置成包括发射功率不同的多个激光发射装置(111)，既能够使每个激光发射装置(111)的发射功率与探测区域的能量需求相匹配，从而提升系统探测距离以及降低系统总功耗，又能够增大激光雷达(10)的探测视场角，实现广角探测功能。
