Facial magnetomyography using an array of optically pumped magnetometers. [PDF]
Clin Neurophysiol PractMeasuring facial muscle activity is crucial in the diagnosis of facial palsy. This study investigated whether contactless Magnetomyography (MMG) using optically pumped magnetometers (OPM) is feasible for visualizing facial muscle activity.An anatomically shaped mask featuring eleven OPM was arranged on one side of the face of five healthy subjects. MMG

High Sensitivity Optically Pumped Quantum Magnetometer [PDF]
The Scientific World Journal, 2013 Quantum magnetometers based on optical pumping can achieve sensitivity as high as what SQUID‐based devices can attain. In this paper, we discuss the principle of operation and the optimal design of an optically pumped quantum magnetometer. The ultimate intrinsic sensitivity is calculated showing that optimal performance of the magnetometer is attained ...
