简要介绍了基于冷原子干涉技术的陀螺仪与重力仪的特点以及国内外研究现状,重点介绍冷原子制备、冷原子分束、反射以及原子内态探测等冷原子干涉关键技术的基本原理及其实现方法。结合深空探测特点,冷原子干涉技术在深空探测领域潜在的应用有两个方面:一方面可应用于深空探测器在飞行、交互、对接以及着陆过程中的自主导航;另一方面可应用于深空探测器引力助推过程中的重力以及加速度的精密测量。
The characteristics of gyroscopes and gravimeters based on cold atomic interferometry and the research status at home and abroad are briefly introduced. The basic principles of key technologies of cold atomic interference such as cold atomic preparation, cold atomic beam splitting, reflection and atomic internal state detection are introduced. Implementation. Combined with the characteristics of deep space exploration, the potential application of cold atomic interference technology in deep space exploration has two aspects: on the one hand, it can be applied to autonomous navigation of deep space probes in flight, interaction, docking and landing; on the other hand, It is applied to the precise measurement of gravity and acceleration in the process of gravitational boosting of deep space detectors.
