  • Patent number: 12259244
    Abstract: An adjuster performs simultaneous irradiation of M laser beams to an atomic beam, where M is a predetermined integer satisfying 3?M. The course of each of the M laser beams intersects with an approach path of the atomic beam. A component, in a direction perpendicular to the approach path of the atomic beam, of the sum of radiation pressure vectors that the M laser beams respectively have is non-zero. A component, in a direction of the approach path of the atomic beam, of the sum of the radiation pressure vectors that the M laser beams respectively have is negative for atoms having speeds greater than the predetermined speed, and positive for the atoms having speeds smaller than the predetermined speed.

  • Patent number: 12241745
    Abstract: A vertical deflection estimation device usable for inertial navigation includes: a gravity gradiometer (10), a known vertical deflection library part (20), a high frequency extraction part (30), and an estimation part (40). The gravity gradiometer (10) measures vertical deflection in accordance with positional movement of the gravity gradiometer (10). The known vertical deflection library part obtains known coarse information of vertical deflection on map in accordance with the positional movement of the gravity gradiometer (10). The high frequency extraction part (20) extracts, from the measured vertical deflection, a high spatial frequency component of the measured vertical deflection. The estimation part (40) corrects the measured vertical deflection to derive estimated vertical deflection as highly accurate vertical deflection by combining the known coarse information of vertical deflection on map with the extracted high spatial frequency component of the measured vertical deflection.

  • Publication number: 20250044099
    Abstract: An inertial sensor includes a dual atom interferometer. A moving standing light wave generation device in the dual atom interferometer generates M (3?M) moving standing light waves. Each of the M moving standing light waves is generated by a pair of counter-propagating laser beams. The moving standing light wave generation device adjusts two-photon detuning of a pair of counter-propagating laser beams corresponding to each of N (2?N<M) moving standing light waves out of the M moving standing light waves such that the difference between an interferometric phase corresponding to one atomic beam obtained by interfering with the M moving standing light waves and an interferometric phase corresponding to the other atomic beam obtained by interfering with the M moving standing light waves stays constant.

  • Publication number: 20250027770
    Abstract: An atomic beam is quantum-mechanically collimated. The atomic beam is irradiated with a pumping laser beam and a filtering laser beam in this order. The pumping laser beam has a wavelength corresponding to a transition between a ground state and an excited state of atoms in the atomic beam. Irradiation with the pumping laser beam causes atoms to make transition from the ground state to the excited state and further relax from the excited state to a metastable state. The filtering laser beam has a wavelength corresponding to a transition between the ground state and the metastable state. By irradiating the filtering laser beam, atoms in the metastable state having velocity components equal to or smaller than a predetermined velocity component ?v in a traveling direction of the filtering laser beam are caused to make transition to the ground state.
