  • All-optical and isotropic magnetometer
    Patent number: 10371764
    Abstract: An optical pumping and isotropic measurement magnetometer. The magnetometer is all-optical in the sense that resonance between Zeeman sub-levels is induced by modulating the intensity or the frequency of the pump beam. Resonance is detected either using the pump beam itself or an unmodulated probe beam. The pump beam is linearly polarised and its polarisation direction is kept constant relative to the direction of the magnetic field to be measured, so that a measurement independent of the orientation of the field can be made.
    Type: Grant

  • Isotropic and integrated optical pumping magnetometer
    Patent number: 9709642
    Abstract: A magnetic resonance optical pumping isotropic magnetometer including a laser, a gas filled cell, a HF discharge circuit, RF magnetic field generating coils surrounding the cell, a first frequency regulating mechanism of an RF generator, a second polarization regulating mechanism of the laser beam, and a third regulating mechanism of the direction of the RF magnetic field. The direction of polarization of the laser beam at an inlet of the cell is orthogonally aligned with the magnetic field to be measured by virtue of a liquid crystal polarization rotator. The magnetometer is well-adapted to an integrated arrangement.
