The effect of spatial sampling on the resolution of the magnetostatic inverse problem
Jussi Nurminen, Andrey Zhdanov, Wan Jin Yeo +6
In magnetoencephalography, linear minimum norm inverse methods are commonly employed when a solution with minimal a priori assumptions is desirable. These methods typically produce…
Effects of head modeling errors on the spatial frequency representation of MEG
Wan-Jin Yeo, Eric Larson, Joonas Iivanainen +5
Optically-pumped magnetometers (OPM) -- next-generation magnetoencephalography (MEG) sensors -- may be placed directly on the head, unlike the more commonly used superconducting qu…
Calibration and localization of optically pumped magnetometers using electromagnetic coils
Joonas Iivanainen, Amir Borna, Rasmus Zetter +6
In this paper, we propose a method to estimate the position, orientation and gain of a magnetic field sensor using a set of (large) electromagnetic coils. We apply the method for c…
Intrinsic Pulsed Magnetic Gradiometer in Earth's Field
Kaleb Campbell, Ying-Ju Wang, Igor Savukov +3
We describe a novel pulsed magnetic gradiometer based on the optical interference of sidebands generated using two spatially separated alkali vapor cells. The sidebands are produce…
Measurement and Simulation of the Magnetic Fields from a 555 Timer Integrated Circuit using a Quantum Diamond Microscope and Finite Element Analysis
P. Kehayias, E. V. Levine, L. Basso +12
Quantum Diamond Microscope (QDM) magnetic field imaging is an emerging interrogation and diagnostic technique for integrated circuits (ICs). To date, the ICs measured with a QDM we…
A Compact Cold-Atom Interferometer with a High Data-Rate Grating Magneto-Optical Trap and a Photonic-Integrated-Circuit-Compatible Laser System
Jongmin Lee, Roger Ding, Justin Christensen +16
The extreme miniaturization of a cold-atom interferometer accelerometer requires the development of novel technologies and architectures for the interferometer subsystems. Here we…
