Abstract

一种激光雷达及其装调方法，激光雷达包括至少一个收发组件(10)，收发组件(10)包括：发射模组(101)、分束模组(102)、接收模组(103)；发射模组(101)发出的出射光信号在穿过分束模组(102)之后，发射到探测区域内，在探测区域内被目标物体(11)反射得到反射光信号，反射光信号在经过分束模组(102)偏转之后，由接收模组(103)接收。该激光雷达的收发组件(10)装调过程中，将发射模组(101)、接收模组(103)依次对准分束模组(102)后固定在基座(100)上；获取接收模组(103)接收的反射光信号，并与预设的光信号阈值进行对比后调节接收模组(103)的位置。激光雷达整机组装时，只需要将多个收发组件(10)进行拼接即可，其装调过程简单快速，探测效果好，后期维护方便。
