Abstract

Point-source atom interferometry (PSI) with cold atoms in a centimeter-scale vacuum cell has applications in inertial navigation. PSI uses light pulses in a Raman configuration to interfere atomic wavepackets in an expanding cloud of laser-cooled atoms. The measurement is inherently multi-axis in a single experimental run, measuring the component of the rotation vector of the system in the plane perpendicular to the Raman beam axis and the acceleration along that axis. A key difference between PSI and conventional atom interferometry is that instead of minimizing the thermal expansion of the cold-atom cloud, PSI exploits the expansion to probe these three quantities simultaneously.
