本文描述了一种光脉冲原子干涉仪，它适用于任何种类的原子，甚至电子和质子及其反粒子，特别是用于检验爱因斯坦等效原理与反氢。该设计通过远离谐振布拉格分束器消除了对谐振激光器的需要，并通过磁约束和原子再循环有效地利用了稀缺的原子。我们希望达到一个初始精度优于1%的反氢的自由落体的加速，这可以提高到百万分之一的水平。
We describe a light-pulse atom interferometer that is suitable for any species of atom and even for electrons and protons as well as their antiparticles, in particular, for testing the Einstein equivalence principle with antihydrogen. The design obviates the need for resonant lasers through far-off resonant Bragg beam splitters and makes efficient use of scarce atoms by magnetic confinement and atom recycling. We expect to reach an initial accuracy of better than 1% for the acceleration of the free fall of antihydrogen, which can be improved to the part-per million level.
