原子干涉测量代表了超精确监测加速度和旋转技术的巨大飞跃，因此也代表了依赖这些量的科学的飞跃。这些传感器是从一种基于物质波而不是光波的新型光学器件发展而来的，可能会导致基本检测极限提高几个数量级。本文介绍了欧洲航天局资助的空间原子干涉仪项目 (SAI) 的现状。 SAI 旨在通过多管齐下的方式，从实验和理论上研究在太空中放置原子干涉仪的各个方面：考虑到量子、相对论和计量科学的各个方面，微重力环境中的设备需求、实际预期的性能限制和潜在的科学应用。落塔兼容原子干涉加速度传感器样机已经设计完成，并已开始其子系统的制造。用于冷却和捕获铷原子的紧凑型模块化激光系统已经组装完成。实现了具有极低相位噪声的紧凑型拉曼激光模块。在原子干涉仪中实现相干原子源的可能方案已经通过实验得到了证明。
Atom interferometry represents a quantum leap in the technology for the ultra-precise monitoring of accelerations and rotations and, therefore, for the science that relies on these quantities. These sensors evolved from a new kind of optics based on matter-waves rather than light-waves and might result in an advancement of the fundamental detection limits by several orders of magnitude. This paper describes the current status of the Space Atom Interferometer project (SAI), funded by the European Space Agency. In a multi-pronged approach, SAI aims to investigate both experimentally and theoretically the various aspects of placing atom interferometers in space: the equipment needs, the realistically expected performance limits and potential scientific applications in a micro-gravity environment considering all aspects of quantum, relativistic and metrological sciences. A drop-tower compatible atom interferometry acceleration sensor prototype has been designed, and the manufacturing of its subsystems has been started. A compact modular laser system for cooling and trapping rubidium atoms has been assembled. A compact Raman laser module, featuring outstandingly low phase noise, has been realized. Possible schemes to implement coherent atomic sources in the atom interferometer have been experimentally demonstrated.
