论文摘要
我们讨论了将光力惯性传感器与冷原子干涉仪的复古反射器相结合的量子混合惯性传感器的设计。这种传感器融合方法可通过冷原子干涉仪提供绝对和高精度的测量，同时以高于原子干涉仪重复速率的频率利用光力学惯性传感器。这可以提高这些系统的整体测量带宽以及鲁棒性和现场部署能力。我们评估哪些参数产生最佳的加速度灵敏度，我们预计从DC到1 kHz的纳米-G水平下有噪声底。
We discuss the design of quantum hybrid inertial sensor that combines an optomechanical inertial sensor with the retro-reflector of a cold atom interferometer. This sensor fusion approach provides absolute and high accuracy measurements with cold atom interferometers, while utilizing the optomechanical inertial sensor at frequencies above the repetition rate of the atom interferometer. This improves the overall measurement bandwidth as well as the robustness and field deployment capabilities of these systems. We evaluate which parameters yield an optimal acceleration sensitivity, from which we anticipate a noise floor at nano-g levels from DC to 1 kHz.
