Abstract

一种激光雷达，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)和分束模组(102)之间还设置有至少一个缩束模组(106)，缩束模组(106)用于减小出射光信号的光束直径。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)后固定在基座上；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；缩束模组(106)用于减小出射光信号的光束直径，经过缩束模组(106)的出射光信号，在至少一个方向上光束直径减小，相当于提高了出射光信号的出射能量密度，提高出射光信号的发射效率，提高探测距离和探测效果。
