本文讨论了光机械惯性传感器与冷原子干涉仪后向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提供了冷原子干涉仪的绝对和高精度测量，同时利用光学机械惯性传感器在频率高于原子干涉仪的重复率。这提高了整体测量带宽，以及这些系统的鲁棒性和现场部署能力。我们评估了哪些参数产生最佳的加速度灵敏度，从中我们预测了从DC到1 kHz的纳米g级的噪声底。(C) 2020美国光学学会
We discuss the design of quantum hybrid inertial sensor that combines an optomechanical inertial sensor with the retroreflector 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. (C) 2020 Optical Society of America
