Abstract
Point source atom interferometry measures a rotation vector projected onto a plane by extracting the phase gradient arising from the mapping of velocity-dependent interferometer phases onto the imaging plane. To extract the phase gradient, spatially-resolved imaging of the fi nal cold-atom cloud is required. In this work, we propose and demonstrate a simple and efficient experimental scheme that calculates the phase gradient from four population ratio images. With this technique, we demonstrate unambiguous two-dimensional measurements of a rotation vector projected onto a plane with applied rotation magnitude ranging from 0.045 deg/s to 5.1 deg/s.Citation
