<p>Technology is disclosed for measuring distances. A measurement device emits a beam that reflects on the surface of an object. The measurement device determines the distance to the object, based on the time of flight of the beam from transmission to capture by the measurement device. The device includes a light source adapted to provide an outgoing reference beam. A detector is aligned to receive a return beam, wherein said return beam results from a reflection of said outgoing reference beam from an object outside of said distance measurement device. A diffuser is provided adjacent to the detector aligned to receive said return beam.</p> |
