Query: Multi-axis Accelerometry and Rotation Sensing using a Point Source Atom
  Interferometer   A point source atom interferometer (PSI) is a device where atoms are split
and recombined by applying a temporal sequence of Raman pulses during the
expansion of a cloud of cold atoms behaving approximately as a point source.
Unlike a conventional light pulse atom interferometer, the PSI can produce a
signal that corresponds to multi-axis rotation only, independent of
acceleration. In addition, it can be used to measure acceleration along one
direction, independent of rotation. Here, we describe a modified PSI that can
be used to measure multi-axis rotation and multi-axis acceleration.
Specifically, this type of PSI can be used to measure two-axes rotation around
the directions perpendicular to the light pulses, as well as the acceleration
in all three directions, with only one pair of Raman beams. Using two pairs of
Raman beams in orthogonal directions sequentially, such a scheme would enable
the realization of a complete atom interferometric inertial measurement unit.
