波前像差是目前原子干涉仪中最大的不确定因素之一。我们给出了一个详细的数值和实验分析的基础上，测量像差从光学窗口。通过在原子重力仪的拉曼光束路径中放置窗口，我们首次验证了诱导偏置与理论非常吻合。该方法可将原子重力仪的不确定度降低一个数量级，误差小于3 × 10(-10)g，适用于各种热原子或超冷原子干涉仪。我们讨论了我们的方法的局限性，潜在的改进，以及它在未来一代实验中的作用。
Wavefront aberrations are one of the largest uncertainty factors in present atom interferometers. We present a detailed numerical and experimental analysis of this effect based on measured aberrations from optical windows. By placing windows into the Raman beam path of our atomic gravimeter, we verify for the first time the induced bias in very good agreement with theory. Our method can be used to reduce the uncertainty in atomic gravimeters by one order of magnitude, resulting in an error of < 3 x 10(-10)g, and it is suitable in a wide variety of atom interferometers with thermal or ultracold atoms. We discuss the limitations of our method, potential improvements, and its role in future generation experiments.
