Steel wire ropes are the vital load-bearing element in many rope transport devices, such as
mine hoists, personal lifts, bridges and cableways. Non-destructive fault detection is a …

This article is designed as a step-by-step guide to optically pumped magnetometers based
on alkali atomic vapor cells. We begin with a general introduction to atomic magneto-optical …

State-of-the-art magnetic field measurements performed in shielded environments under
carefully controlled conditions rarely reflect the realities of those applications envisioned in …

We present a portable optically pumped magnetometer instrument for ultrasensitive
measurements within the Earth's magnetic field. The central part of the system is a sensor …

Research on quantum sensors for the detection of magnetic fields (quantum
magnetometers) is one of the fast-moving areas of Quantum Technologies. Since there exist …

We demonstrate an alignment-based Rb 87 magnetometer that is immune to nonlinear
Zeeman (NLZ) splitting, addressing an important problem in alkali-metal atomic …

Atomic vapour magnetometers sense the local magnetic field strength by measuring the
resulting precession rate of a well-defined quantum state. An essential prerequisite for this …

The detection dead zones and heading errors induced by light shifts are two important
problems in optically pumped scalar magnetometry. We introduce an atomic-orientation …

Compensating the magnetic interference related to airplane maneuvers is essential to high-
precision aeromagnetic measurement. In estimating the compensation coefficients …

Magneto-optical double-resonance magnetometers are attractive candidates for sensitive
measurements of magnetic fields but suffer from a fundamental problem known as the “dead …
