Abstract: A distance measuring device that measures a distance to an object. The distance measuring device includes: a light source that emits pulsed light; a reflector that reflects and radiates, as radiation light, the pulsed light emitted from the light source, and reflects object light that is the radiation light reflected by the object and returning; and an imager that captures the object light reflected by the reflector. The pulsed light emitted from the light source is diffused light. The light source and the imager are located to face the reflector. The reflector radiates, as the radiation light, light in a shape with a long axis and a short axis. The imager performs exposure in synchronization with the pulsed light to image the object light.
