摘    要:原子干涉重力仪凭借高精度小型化的优势,在高精度重力测量方面具有良好的发展前景。目前原子干涉重力仪在使用过程中,通常使用传统拉曼三脉冲方法对原子团进行分束合束的干涉操控,但不同的干涉操控方法会导致最终原子干涉条纹的测量精度的不同。介绍了几种原子干涉的操控方法,在传统原子干涉操控方法的基础上,增大原子干涉闭合回路的干涉面积,进而能够提高原子干涉条纹的分辨率。对这几种方法进行了比较,分析了每种方法需要的实验条件,得出了几种原子干涉操控方法对原子干涉重力仪的测量的影响。提出了提高原子干涉重力仪测量精度的建议,为后续更高精度的原子干涉重力仪的研究提供了参考。

关 键 词:原子干涉重力仪  干涉操控  干涉面积  原子干涉条纹分辨率  闭合回路

Review on Atomic Interference Manipulation Methods for Gravity Acceleration Measurement
Abstract:Atomic interference gravimeter has good development prospects in high-precision gravity measurement with the advantages of high-precision and miniaturization.At present,during the use of atomic interference gravimeters,the traditional Raman three-pulse method is usually used in the interference manipulation of the splitting and combining on the atomic masses,but different interference control methods will lead to different measurement accuracy of the final atomic interference fringe.Several methods of atomic interference manipulation are introduced.These new methods of atomic interference manipulation are based on the traditional atomic interference manipulation method,but the interference area of the atomic interference closed loop is increased,thus the resolution of the interference fringes can be improved.Finally,these atomic interference manipulation methods are compared,and the experimental conditions required for each method are analyzed.The contribution of several atomic interference manipulation methods to the measurement of atomic interference gravimeter is obtained.Some suggestations for improving the measurement accuracy of the atomic interference gravimeter are put forward,which provides a reference for further research on atomic interference gravimeter with higher accuracy.
Keywords:atomic interference gravimeter  interference manipulation  interference area  atomic interference fringe resolution  closed loop
