Abstract
(EN)
A distance detection device (100). The distance detection device (100) comprises a light source (103), a scanning module (102) and a detector (105); the light source (103) is used for emitting a light beam; the scanning module (102) comprises a first optical module (130), a second optical module (140) and driving devices (150, 151), the first optical module (130) and the second optical module (140) being sequentially located on the optical path of the light beam emitted from the light source (103), and the driving devices (150, 151) driving the first optical module (130) and the second optical module (140) to move, such that the light beam emitted from the light source (103) is sequentially projected towards different directions, and forms a strip-shaped scanning range after exitting from the scanning module (102); and the detector (105) is used for converting at least part of return light (112) reflected by a detection object (101) into an electrical signal, the electrical signal being used for measuring the distance between the detection object (101) and the distance detection device (100).
