  • Publication number: 20190376790
    Abstract: Disclosed is a hybrid inertial measurement system including a cold atom interferometric inertial sensor having a laser source generating a sequence of laser pulses towards a cold atom burst and a conventional inertial sensor attached to the inertial reference frame of the interferometric inertial sensor. The hybrid system includes a signal processing system suitable for receiving an inertial measurement signal from the conventional inertial sensor and for generating in real time a non-linear frequency modulation signal, the feedback loop electronic system being configured to modulate in real time the central optical frequency of the laser according to the modulation signal, such that the cold atom interferometric inertial sensor generates a first hybrid inertial measurement signal by atomic interferometry corrected for the relative movements of the inertial reference frame.

  • Patent number: 9134450
    Abstract: A cold atom gravity gradiometer system includes a laser source that generates a laser beam that propagates along a propagation direction. The system further includes a reflector that reflects a portion of the laser beam and transmits another portion of the laser beam (the transmitted portion). A second reflector spatially separated from the first reflector along the propagation direction reflects the transmitted portion of the laser beam.

  • Patent number: 8373112
    Abstract: The disclosure relates to a cold atom interferometry sensor that includes: a source of atoms; a dual-frequency laser capable of generating a first Raman dual-frequency laser beam; a reflector arranged so as to reflect the first Raman dual-frequency laser beam in order to generate a second Raman dual-frequency laser beam, the first laser beam and the second laser beam propagating in different directions in order to obtain atomic interference fringes from the emission of cold atoms obtained from the atom source; characterized in that the reflector is further arranged so as to enable multiple reflections of the first beam on surfaces of the reflector, so that the first beam and the multiple reflections thereof allow the capture of atoms from the atom source in order to obtain the cold atoms.

  • Patent number: 6548809
    Abstract: An electromagnetic device for producing cold neutral atoms having a ferromagnetic structure with four poles disposed in the same plane XOY excited by main coils (the quadrupole) supplying the main excitation, and two additional poles (the dipole) oriented along an axis Z and perpendicular to the plane of said four poles, the poles being magnetically coupled by one or more yokes.
