Field validation of GNSS-independent positioning enhancement using a wearable ultra-stable quantum magnetometer
Stirling Scholes, Dominic Hunter, Courtney Dyer +8
Increasing the resilience of positioning systems that currently rely on Global Navigation Satellite System (GNSS) signals can be achieved by incorporating stable and sensitive meas…
Spatial dealiasing of classical geomagnetic survey data through use of a microfabricated wearable quantum magnetometer
Stirling Scholes, Alissa Forsythe, Courtney Dyer +6
Geomagnetic surveys provide insight into the subsurface for a range of applications, from fundamental understanding of geological processes, to mineral exploration and locating une…
Intrinsic atomic calibration of oscillating magnetic fields in ULF and VLF bands
Zak Johnston, Paul F. Griffin, Erling Riis +3
We present a method for absolute calibration of received radio-frequency in the ultra low frequency (ULF), and very low frequency (VLF) range. This is achieved with the use of a ra…
High-Resolution Atomic Magnetometer-Based Imaging of Integrated Circuits and Batteries
Dominic Hunter, Marcin S. Mrozowski, Stuart J. Ingleby +7
Optically pumped magnetometers (OPMs) have emerged as a powerful technique for high-resolution magnetic field imaging. However, achieving sub-millimeter spatial resolution at sub-p…
A triaxial vectorization technique for a single-beam zero-field atomic magnetometer to suppress cross-axis projection error
Rach Dawson, Marcin S. Mrozowski, Dominic Hunter +4
Zero-field optically pumped magnetometers (OPMs) have emerged as an important technology for biomagnetism due to their ulta-sensitive performance, contained within a non-cryogenic…
Distributed network of optically pumped magnetometers for space weather monitoring
M. S. Mrozowski, A. S. Bell, P. F. Griffin +6
Spatial variation in the intensity of magnetospheric and ionospheric fluctuation during solar storms creates ground-induced currents, of importance in both infrastructure engineeri…
Longitudinal spin-relaxation optimization for miniaturized optically pumped magnetometers
A. P. McWilliam, S. Dyer, D. Hunter +7
The microfabrication of cesium vapor cells for optically pumped magnetometry relies on optimization of buffer gas pressure in order to maximize atomic coherence time and sensitivit…
Optical pumping enhancement of a free-induction-decay magnetometer
Dominic Hunter, Marcin S. Mrozowski, Allan McWilliam +4
Spin preparation prior to a free-induction-decay (FID) measurement can be adversely affected by transverse bias fields, particularly in the geophysical field range. A strategy that…
A Digital Alkali Spin Maser
Stuart Ingleby, Paul Griffin, Terry Dyer +2
Self-oscillating atomic magnetometers, in which the precession of atomic spins in a magnetic field is driven by resonant modulation, offer high sensitivity and dynamic range. Phase…
