Abstract: A distance measuring device for measuring the distance to an object is provided, including a light-emitting module, a driving assembly disposed in the light-emitting module, and a light-receiving module. The light-emitting module has a housing, a light source disposed in the housing, a light grating element, and an optical path adjuster. The light source emits a measuring light through the optical path adjuster and the light grating element. The driving assembly can drive the optical path adjuster or the light grating element to move relative to the housing. The light-receiving module receives the measuring light which is reflected by the object to obtain distance information of the object.
