The device comprises a gyro rotor shaped as a spherical ball (16) and rotating about a spin axis . The ball is supported in a spherical recess (15) in a housing or seat (14) fixedly connected to the envelope (10). The transmitted or received radiation passes through central parts (23, 20) of the ball and seat. The parts for this purpose are transparent for the radiation. The parts (23, 20) of the ball and seat form an adjustable diffraction prism similar to an 'optical wedge' for the transmitted radiation so that a plane wall (44) of the ball can be set in any desired angle relative to a plane wall (45) of the seat. - The direction (L') of the radiation lobe for outgoing and/or incoming radiation energy is then determined by the refractive index for the parts of the ball and seat, where the radiation passes, possibly in combination with the diffraction produced by a lens (12) arranged in series. The refractive index is so selected that, at an angular change of the gyro rotor or ball (16), the radiation lobe (L') will undergo an equally large angular change so that it always coincides with the spun axis (03). |
