Claim 18:
19. An inertial point-source matter-wave atom interferometer gyroscope comprising:
an analyzer that receives a plurality of fringe images of gyroscope atoms, the fringe images comprising: a first fringe image that comprises a first fringe phase, a second fringe image that comprises a second fringe phase; and a third fringe image that comprises a third fringe phase, a fourth fringe image that comprises a fourth fringe phase, wherein the first fringe phase, the second fringe phase, the third fringe phase, and the fourth 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 comprising an acceleration, a rotation direction, and a rotation rate of the inertial point-source matter-wave atom interferometer gyroscope relative to the gyroscope atoms.
