Scale factor corrections for point source atom interferometry

ORAL

Abstract

Point source atom interferometry (PSI) is a promising candidate for realizing compact, high-sensitivity inertial sensors. Here, we present results on a magneto-optical trap-based PSI atom interferometer using 87Rb and methods to improve the scale factor stability for rotation sensing. Scale factors in PSI are dependent on the initial cloud shape and size, and analytic corrections to the scale factor exist for Gaussian density profiles. We present work developing corrections for arbitrary initial cloud shapes and discuss the relative benefits for overall gyroscope stability.
