Ultimate parameters of an all-optical MX resonance in Cs in ultra-weak magnetic field
, 2023 We present the results of studying the parameters of the magnetic MX resonance in an all-optical sensor built according to the two-beam Bell-Bloom scheme in nonzero ultra-weak magnetic fields in which the effects of spin-exchange broadening suppression ...

Source imaging method based on diagonal covariance bases and its applications to OPM-MEG
NeuroImageMagnetoencephalography (MEG) is a noninvasive imaging technique used in neuroscience and clinical research. The source estimation of MEG involves solving a highly underdetermined inverse problem, which requires additional constraints to restrict the solution space. Traditional methods tend to obscure the extent of the sources.

An optically pumped magnetic gradiometer for the detection of human biomagnetism [PDF]
We realise an intrinsic optically pumped magnetic gradiometer based on non-linear magneto-optical rotation. We show that our sensor can reach a gradiometric sensitivity of 18 fT cm−1√Hz−1 and can reject common mode homogeneous magnetic field noise with ...

Exploring Directed Connectivity Patterns of OPM-MEG with Multivariate Transfer Entropy
AbstractWe explored the directed connectivity of magnetoencephalography data recorded via Optically Pumped Magnetometers (OPM-MEG). Ten healthy adult participants were scanned twice while watching a movie in an OPM-MEG system. Beamformer source localisation was employed to obtain source time series within 62 cortical brain regions.

Benchmarking OPM-MEG using Auditory Evoked Responses
Magnetoencefalografi (MEG), som icke-invasivt mäter det magnetfält som genereras från neuronkluster, har potential att användas i kliniska miljöer för diagnos och prediktion av behandlingssvar. Konventionell MEG använder supraledande kvantinterferensdetektorer (SQUIDs) som kräver kryogen kylning.

Noise Reduction Algorithms for OPM-MEG data
Magnetoencephalography (MEG) using optically pumped magnetometers (OPM) offerssuperior spatial resolution and flexibility compared to the conventional MEG-systems.However OPM-MEG is highly vulnerable to interference such as environmental noiseand muscle movements which provides a need for noise reduction techniques.
