Research Status and Analysis of Atom Interferometer Gyroscope
【摘要】 自1991年实验演示以来,利用中性原子的物质波干涉进行惯性传感逐渐成为量子精密测量领域的研究热点。其中,光脉冲原子干涉仪在转动角速率测量方面展示了成为超高灵敏度传感器的潜力,在高精度惯性导航、基础物理学和地球物理学研究等领域具有广阔的应用前景。光脉冲原子干涉陀螺仪历经了第一代原理验证与第二代高性能实验室演示的发展,正处于从实验室向工程应用转化的重要阶段。从原子干涉陀螺仪的测量原理出发,对已有的原子干涉陀螺仪进行了分类介绍,并对近年来制约原子干涉陀螺仪动态环境应用的提高数据更新率、带宽和动态范围等问题的研究现状进行了分析和讨论。
【Abstract】 Since its experimental inception in 1991, the inertial sensing using matter-wave interferometers of neutral atoms has become one of research focuses in fields of quantum precision measurement. Among them, the light-pulse atom interferometer(LPAI) has shown its potential as an ultra-high sensitive sensor for measuring rotation rate, and found wide applications in fields of inertial navigation, fundamental physics and geophysics researches. After undergoing the first generation for proof-of-principle and the second generation for demonstration of high performances, LPAI based gyroscope is moving from laboratories into dynamic field environments. In this paper, the measurement principle of the atom interferometer gyroscope is introduced, and then the technical characteristics and development history of the atom interferometer gyroscope is described. Besides, the classification and research status of the current LPAI based gyroscopes are introduced. Finally, the research status of the basic technical problems of improving the data update rate, bandwidth and dynamic range, which restrict the application of the LPAI based gyroscope in the dynamic environment, is analyzed and discussed.
