Closed-Loop Atomic Interferometric Inertial Sensor for Dynamic Measurement

This paper presents progress toward a closed-loop atomic interferometric inertial sensor. We propose a method for independent closed-loop feedback control of atomic interfero-metric phase shifts induced by acceleration and angular velocity through precise manipulation of Raman lasers' two-photon frequency detunings. By employing counter-propagating continuous atomic beams and a dual-loop control scheme, we demonstrate stable operation and rapid re-locking following perturbations. Our approach represents a significant step toward the practical deployment of atomic interferometric inertial sensors in dynamic environments.
