A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

This report shows the results of a test survey aimed at comparing four different UAV-based (Unmanned Aerial Vehicle) magnetometers and their capabilities to detect various infrastructure utilities.

Fluxgate magnetometers represent a cornerstone technology in magnetic field measurements, utilising a ferromagnetic core excited by an alternating current to gauge weak, quasi‐stationary magnetic ...

This report shows the results of a test survey aimed at collecting reference data using four different UAV-based (Unmanned Aerial Vehicle) magnetometers against UXO (Unexploded Ordnance) surrogate ...

Magnetic fields are everywhere, from the human body to the metal in a buried land mine. Even molecules such as proteins generate their own distinctive magnetic fields. Both magnetic resonance imaging ...

Smartphones have dozens of hidden sensors that power everyday features. From accelerometers and gyroscopes to proximity and ...

The tree diagram shows three perspectives for evaluating the sensitivity limits (green leaves). These perspectives are interconnected (red dashed lines) and are constrained by fundamental principles ...

The researchers fabricated chip-based interferometers (pictured) to measure how light propagating through a magneto-optic material changed in response to a magnetic field. WASHINGTON — Researchers ...
