Abstract of the Disclosure The device comprises a lens and a source for emitting a beam of parallel light rays or ultrasonic rays at right angles to a flat dioptric element. The lens surface which is located opposite to the radiation-emitting source is flat and the lens surface located opposite to the dioptric is element is such that the refracted rays are incident upon the dioptric element at a constant angle. The wave which is incident upon the dioptric element and corresponds to the beam refracted from the lens and the wave refracted from the dioptric element and corresponding to the incident wave are in phase along a predetermined path on the surface of the dioptric element. -1-
