| titleOfInvention | DEVICE AND METHOD FOR LOCATING THE DIRECTION OF AN ATOMIC JET. |
| abstract | Systems and methods for determining the angular direction of an atomic beam (2) with respect to the reference axis (4) of the beam. For an atomic beam of non-relativity, a pair of laser beams of equal frequency and opposite propagation (6 and 8) intersects the atomic beam at a known angle with respect to the reference axis (4), preferably perpendicular. The direction of the atomic beam is deduced from the frequency difference between the resonant peaks in the fluorescence of the laser beam by scanning the laser frequency. For a relativity atomic beam, a pair of laser beams (46 and 48) intersects the atomic beam at different locations at equal predetermined angles. The direction of the atomic beam is determined by observing the difference between the resonant absorption peaks in the intensities of the transmitted laser beam (38), the frequencies or the angles of the laser beam (38) between the atomic beam and the laser beam ( 38) being preferably selected to minimize the widths of the resonance peaks. In both cases of relativity and non-relativity, an FM derivative spectroscopy technique is used, whereby the derivatives of the intensity signals of the laser beam are obtained, and the zero point crossings of the derivative signal are used from so as to precisely locate the peaks of resonance intensity. |
