    摘要:

    作为新一代陀螺仪的代表,原子陀螺凭借其理论上的超高精度、卓越的长期稳定性以及小型化集成化的巨大潜力,已成为高精度惯性导航领域的研究焦点。其中,原子干涉陀螺作为原子陀螺的一种,引起了惯导领域的广泛关注。本文系统梳理了原子干涉陀螺技术发展脉络,从基本原理出发,阐释原子源制备、干涉环路构建及相位解算等关键技术环节,分析灵敏度、极限精度等关键参数的内在关联与制约机制,并且揭示了数据更新率受限、动态范围窄等工程化瓶颈的物理本质。最后,文章指出原子干涉陀螺的未来发展方向应聚焦于:解决外部干扰问题以提升精度、改进芯片工艺实现小型化和集成化、优化组合惯性传感器、提升数据更新率以及探索扩大动态范围等方面。

    Abstract:

    As a representative of the next generation of gyroscopes , atomic gyroscopes have become a focal point of research in the field of high-precision inertial navigation and has garnered significant attention due to its theoretically ultra-high precision, exceptional long-term stability, and immense potential for miniaturization and integration. Among them, the atom interferometric gyroscope, as a type of atomic gyroscope, had attracted widespread interest in the field of inertial navigation.. The development of atomic interferometric gyroscopes was systematically reviewed. Beginning with fundamental principles, it elaborates on critical technical components including atomic source preparation, interferometric loop construction, and phase resolution. Through rigorous analysis, the paper establishes intrinsic correlations between core performance parameters such as sensitivity and ultimate accuracy while elucidating their mutual constraint mechanisms. Furthermore, it reveals the physical origins of engineering bottlenecks including limited data update rates and narrow dynamic ranges.?Finally, the article outlines future development directions and trends for atomic interference gyroscopes, emphasizing the need for in-depth research in several areas: solving external interference issues to improve accuracy, improving chip processing technology for miniaturization and integration, enhancing combined inertial sensors, increasing data update rates, and exploring ways to expand dynamic range.
