Attitude-Independent Route Tracking for Subsea Power Cables Using a Scalar Magnetometer under High Sea Conditions

Remote Sensing
To overcome the shortcoming wherein the accuracy of subsea cable detection can be affected by the determination of the bias vector, scale factors, and non-orthogonality corrections of the vector magnetometer, a real-time attitude-independent route ...

An isotropic earth field scalar magnetometer using optically pumped helium 4

, 1994
Optical pumping was originally suggested by Kastler [1] in 1950 and since the early 1960's numerous helium magnetometers based upon that technique have been developed.

Many body effect induced energy gap in an optically pumped graphene system

, 2014
We develop a simple way to investigate the energy gap induced by many body effect in optically pumped graphene at different carrier densities. The exchange self-energy and energy dispersions are obtained analytically at the long wave limit. An energy gap

The effect of sensor-to-source distance on magnetic neuromuscular signals

Scientific Reports
Magnetomyography (MMG) can be used as a contactless modality to study the neuromuscular system. On the one hand, being contactless is a practical advantage as there is no need to prepare skin or attach electrodes as in electromyography (EMG).

Optimizing longitudinal spin relaxation in miniaturized optically pumped magnetometers [PDF]

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 sensitivity to external magnetic signals.

AC susceptibility measurement of magnetic nanoparticles using an optically pumped magnetometer and a flux transformer

Magnetic particle imaging (MPI) is used to detect small magnetic fields in magnetic nanoparticles (MNPs). As a first step in MPI systems, we proposed an AC susceptibility measurement system with an optically pumped magnetometer (OPM) based on a flux ...
