We demonstrate an atom interferometer measurement protocol compatible with operation on a dynamic platform. Our method employs two open interferometers, derived from the same atomic source, with different interrogation times to eliminate initial velocity dependence while retaining precision, accuracy, and long term stability. We validate the protocol by measuring gravitational tides, achieving a precision of 4.5 μGal in 2000 runs (6.7 h), marking the first demonstration of inertial quantity measurement with open atom interferometry that achieves long-term phase stability.
我们展示了一种与动态平台操作兼容的原子干涉仪测量协议。我们的方法采用了两个源自同一原子源的开放式干涉仪,它们具有不同的询问时间,以消除初始速度依赖性,同时保持精度、准确性和长期稳定性。我们通过测量引力潮汐来验证该协议,在2000次运行(6.7小时)中实现了4.5微伽的精度,这标志着首次使用开放式原子干涉测量法进行惯性量测量并实现了长期相位稳定性。
