Abstract
一种测距模组(30)和测距装置(100)。测距模组(30)包括光源(32)、光路改变元件(33)和探测器(35)。光路改变元件(33)位于光源(32)的出射光路上并用于将光源(32)的出射光路和探测器(35)的接收光路合并。光路改变元件(33)包括基材(331)和形成在基材(331)上的反射膜(333)。反射膜(333)上开设有通光孔(3332)。基材(331)对应通光孔(3332)处的区域设置为透光区(3312)。光源(32)发射的光脉冲序列穿过透光区(3312)及通光孔(3332)后出射。经探测物反射回的光脉冲序列被反射膜(333)反射后由探测器(35)接收。探测器(35)用于根据接收的光脉冲序列确定探测物相对测距模组(30)的距离和/或方向。
