An Accurate Vector Magnetometer via Zeeman Rabi Oscillations
Thanmay S. Menon, Dawson P. Hewatt, Christopher Kiehl +3
Accurate magnetic field direction sensing in compact platforms is critical in applications spanning magnetic navigation, space science, and biomedical imaging. We demonstrate a sin…
Accurate vector optically pumped magnetometer with microwave-driven Rabi frequency measurements
Christopher Kiehl, Thanmay S. Menon, Svenja Knappe +2
Robust calibration of vector optically pumped magnetometers (OPMs) is a nontrivial task, but increasingly important for applications requiring high-accuracy such as magnetic naviga…
Investigating the hyperfine systematic error and relative phase in low spin-polarization alkali FID magnetometers
D. P. Hewatt, M. Ellmeier, C. Kiehl +4
Alkali-metal optically-pumped magnetometers are prone to inaccuracies arising from the overlap of the average F = I + 1/2 and F = I - 1/2 ground-state Zeeman resonances. We employ…
Correcting heading errors in optically pumped magnetometers through microwave interrogation
Christopher Kiehl, Thanmay S. Menon, Dawson P. Hewatt +3
We demonstrate how to measure in situ for heading errors of optically pumped magnetometers (OPMs) in the challenging parameter regime of compact vapor cells with imperfect optical…
