Abstract
We present two methods to achieve real-time inertial phase compensation in atom interferometers. Both methods, based on jumping of the position of the retroreflection mirror or frequencies of Raman lasers, demonstrate similar state-of-the-art performance on our cold-atom gyroscope, comparable to that of the reference method, based on optical phase jumping. These alternative approaches broaden the scope of applications for real-time inertial phase compensation methods in atomic interferometers, particularly for space applications.
