Most standard MEG systems have gradiometers rather than magnetometers to suppress distant noise sources. Our team
@TheCHBH therefore developed an Optically Pumped Magnetic Gradiometer measuring human brain activity while suppressing e.g. lift artefacts arxiv.org/abs/2402.10113

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...
