Method of phase extraction between coupled atom interferometers using ellipse-specific fitting

Not Accessible

Your library or personal account may give you access

Abstract

We present a method of analysis involving ellipse-specific fitting of sinusoidally coupled data from two gravimeters in a gradiometer configuration. This method permits rapid extraction of induced gradient phase shifts in the presence of common-mode vibrational phase noise. Gravity gradients can be accurately measured in the presence of large vibrational accelerations.
