DOI: 10.1016/j.jneumeth.2020.108592
Abstract: BACKGROUND Many magnetoencephalographs (MEG) contain, in addition to data channels, a set of reference channels positioned relatively far from the head that provide information on magnetic fields not originating from the brain. This information is… read more here.

DOI: 10.1063/1.5098088
Abstract: We present an experimental noise characterization of a miniature single-beam absorption-based optically-pumped magnetometer with a noise floor of 7 fT/Hz1/2 operating in the spin-exchange relaxation-free regime. We experimentally evaluate noise arising from the laser intensity, laser… read more here.

DOI: 10.1093/gji/ggaa539
Abstract: Beamforming and backprojection methods offer a data-driven approach to image noise sources, but provide no opportunity to account for prior information or iterate through an inversion framework. In contrast, recent methods have been developed to… read more here.
