论文摘要
基于原子干涉法的重量表具有在建立重力网络，地球物理学以及重力辅助导航方面具有广泛的应用。在这里，我们在实验上展示了在嘈杂的城市环境中运行的便携式原子重量表。尽管嘈杂的外部振动受到影响，但我们的便携式原子重量表的灵敏度良好，高达65 ugal/\ sqrt {hz}，在4000 s的整合时间后的分辨率为1.1 ugal，与最新的原子量化物相当。我们的成就为将便携式原子重量表带入现场应用铺平了道路，例如在移动平台上的重力调查。
The gravimeter based on atom interferometry has potentially wide applications on building the gravity networks, geophysics as well as gravity assisted navigation. Here, we demonstrate experimentally a portable atom gravimeter operating in the noisy urban environment. Despite the influence of noisy external vibrations, our portable atom gravimeter reaches a sensitivity as good as 65 uGal/\sqrt{Hz} and a resolution of 1.1 uGal after 4000 s integration time, being comparable to state-of-the-art atom gravimeters. Our achievement paves the way for bring the portable atom gravimeter to field applications, such as gravity survey on a moving platform.
