- 요약In this thesis, I describe the development of a novel approach to atomic vector magnetometry that utilizes the directional information contained in microwave-driven Rabi oscillations between the hyperfine manifolds of 87Rb. These measurements take place in a heated microfabricated vapor cell embedded within a microwave cavity with a single optical axis. By utilizing a complete model for the atom-microwave coupling and collisional decoherence, I show how nontrivial spin dynamics during Rabi oscillations from spin-exchange collisions in the strong-driving limit characterizes basic properties of the atomic vapor. Additionally, I illustrate how this theoretical framework enables the in-situ correction of heading errors in free induction decay (FID) signals, operating under realistic conditions of imperfect pumping and high buffer gas pressures that often hinder other methods of heading error-free measurements. Finally, I demonstrate vector magnetometry by referencing Rabi measurements from multiple hyperfine transitions against calibrated microwave polarization ellipses (MPEs). I further show how to accurately reference an intrinsic magnetometer frame to the attitude of a probe beam from the magnetic field orientation where the Rabi oscillation signal zeroes. This Rabi Amplitude Nulling to determine Beam Attitude (RANBA) technique could be applied to calibrate a vector gradiometer and to monitor overall drifts in the intrinsic magnetometer frame. While state-of-the-art vector magnetometers calibrate systematic errors arising from drifts through sensor or bias field rotations, this research lays the groundwork towards achieving practical vector calibration by only leveraging electromagnetic field manipulations; thereby circumventing the need for intricate mechanical rotations or the application of large bias fields.
