| 摘 要： | 原子作为一种微观粒子,具有波粒二象性.利用粒子的波动性,可以产生类似于光波的Sagnac效应,由此实现基于原子波干涉的原子干涉陀螺仪.其中原子干涉有内态干涉和物质波干涉两种.在围成相同面积的情况下,原子干涉陀螺仪的灵敏度将比光学陀螺仪高出10个量级以上,适宜于水下和空间等长时间惯性导航的应用.本文详细地论述了原子干涉陀...

| Abstract: | Atom, as a kind of particulates, has nature properties of duality of wave and particle. Sagnac effect can be demonstrated by an interferometer, so atom interferometric gyroscope can be obtained by atomic state interferometer and matter-wave interferometer with atom guide. The sensitivity of atom interferometric gyroscope will be 1010 higher than optical gyroscope under the same enclosed area. It can be applied in the navigation of underwater and space. The principle, significant technology and development of atom interferometric gyroscopes will be discussed in this paper. |
