Coriolis effect due to laser beam tilting in an atom interferometer
Abstract:
The Coriolis effect can introduce significant systematic errors in atom interferometers. This study examines the coupling effect between the Coriolis effect and the Raman beams-orientation in a fountain atomic gravimeter. Theoretical analysis indicates that the Coriolis effect is correlated with the orientation of the Raman beams, and tilt modulation experiments were conducted to substantiate this correlation. Furthermore, by aligning the orientations of the atomic fountain, the vacuum chamber, and the Raman mirror, we achieved simultaneous suppression of both the Coriolis effect and the tilt effect to sub-μGal levels in a high-precision atomic gravimeter. This work offers guidance on assessing systematic errors in high-precision atomic gravimeters.
