  • Inertial point-source matter-wave atom interferometer gyroscope and extracting inertial parameters
    Patent number: 11940276
    Abstract: An inertial point-source matter-wave atom interferometer gyroscope includes an analyzer that receives fringe images of gyroscope atoms and includes: a first fringe image that includes a first fringe phase, a second fringe image that includes a second fringe phase; and a third fringe image that includes a third fringe phase, wherein the first fringe phase, the second fringe phase, and the third fringe phase are different; a phase mapper of the analyzer that produces a interferometric phase map for the gyroscope atoms from the fringe images of the gyroscope atoms; and a fitter of the analyzer in communication with the phase mapper and that receives the interferometric phase map from the analyzer and determines inertial parameters of the gyroscope atoms from the interferometric phase map, the inertial parameters including an acceleration and a rotation rate of the inertial point-source matter-wave atom interferometer gyroscope relative to the gyroscope atoms.
