Optically Pumped Nuclear Magnetometer

Review of Scientific Instruments, 1963
A continuous recording total earth's field magnetometer has been demonstrated which utilizes optical pumping in He3 and the resultant polarization of the nuclear spins. The device operates as a ``self-oscillator'' at the Larmor frequency of the ground state atoms. The oscillator has a ``Q'' of 104 in a 0.5-G field.

Reducing crosstalk in optically-pumped magnetometer arrays

Physics in Medicine & Biology, 2019
Optically pumped magnetometers (OPMs) operating in the spin-exchange relaxation-free regime are emerging as alternative sensors to superconducting quantum interference devices (SQUIDs) for magnetoencephalography (MEG). As the number of OPMs in a single imaging system increases to rival SQUID MEG systems, cross-talk between nearby sensors limits the ...
