Abstract

Tune-out wavelengths measured with an atom interferometer are sensitive to laboratory rotation rates because of the Sagnac effect, vector polarizability, and dispersion compensation. We observed shifts in measured tune-out wavelengths as large as 213 pm with a potassium atom beam interferometer, and we explore how these shifts can be used for an atom interferometer gyroscope.

摘要

由于萨格纳克效应、矢量极化率和色散补偿，用原子干涉仪测量的失谐波长对实验室旋转速率敏感。我们用钾原子束干涉仪观察到测量的失谐波长偏移高达213皮米，并且我们探索了如何将这些偏移用于原子干涉仪陀螺仪。
