Abstract:Nowadays, optically pumped magnetometers (OPMs) are gaining popularity in magnetoencephalography (MEG). However, like all sensors that work with biomagnetic signals, they are highly demanding to a low level of external magnetic field in the experimental environment. In the current paper, we proposed the experimental comparison of OPMs signal quality by recording their signal in two different magnetically-shielded rooms (MSRs) with different types of active suppression. Firstly, we conducted experiments in MSR … Show more
