Kang, Seji — Inertial sensing using an expanding atomic point source

Point source atom interferometry (PSI) provides a compact tool to measure rotation and acceleration from phase differences between two atomic states. In an expanding laser-cooled atomic source within the π/2–π–π/2  Raman pulses, rotation in the perpendicular plane to the Raman beams generates interferometer phases leading to spatial fringes in the atomic state populations. The acceleration along the Raman beam determines the phase offset to the fringes. Here, we introduce our recent methods for extracting rotation and acceleration from fringes and discuss about its sensitivity and stability.
