Patent number: 11054489Abstract: A vector magnetometer comprises a cell to be filled with an atomic gas, an optical source and a photo-detection device. The optical source is configured to emit towards the cell: a first and a second optical beam, called probe beams, that are polarised linearly, a third optical beam, called the pump beam, linearly polarised. The polarisation directions of the probe beams and the polarisation direction of the pump beam are not coplanar. The photo-detection device is configured to receive light from the probe beams that have passed through the cell. The probe beams can have the same propagation direction. The polarisation direction of the pump beam can form an angle of 45°±10° with the polarisation direction of each of the probe beams.Type: GrantFiled: July 15, 2019Date of Patent: July 6, 2021Assignee: COMMISSARIAT À L'ÉNERGIE ATOMIQUE ET AUX ÉNERGIES ALTERNATIVESInventors: Augustin Palacios Laloy, François Beato, Gaëtan Lieb

Patent number: 10684130Abstract: A method for detecting rotation of a carrier utilizes a device embedded in said carrier that comprises an enclosure containing a gaseous mixture of an alkali metal and a noble gas. The method includes a step of starting up (DEM-MEOP) the device during which the noble gas is polarised by utilizing metastability exchange optical pumping. The start-up step is followed by a step of acquisition (MES-SEOP) by the device of a signal representative of said rotation during which the noble gas is maintained polarised by utilizing spin exchange optical pumping. The invention extends to the device and to an inertial navigation unit integrating said device and to an inertial navigation method implementing the method for detecting rotation of the carrier.Type: GrantFiled: June 22, 2018Date of Patent: June 16, 2020Assignees: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES, SAFRANInventor: Augustin Palacios Laloy
