Abstract

一种测距装置(100)，包括：发射组件(110)出射光脉冲序列，接收组件(150)接收经物体反射回的至少部分光脉冲序列；光路改变元件(120)将发射组件(110)的出射光路和接收组件(150)的接收光路合并，准直元件(130)对发射组件(110)的出射光束进行准直，以及将经物体反射回的至少部分光脉冲序列汇聚至接收组件(150)；固定组件(140)将发射组件(110)、接收组件(150)、光路改变元件(120)和准直元件(130)相互固定；其中，发射组件(110)和/或接收组件(150)通过至少第一固定方式和第二固定方式与固定组件(140)相互固定，第一固定方式的固定速度高于第二固定方式，第二固定方式的固定强度高于第一固定方式。该测距装置(100)，不仅提供了充足的空间多自由度调节，而且提高了测距装置(100)的组成部分固定的可靠性。
