Optically-Pumped Magnetometers for MEG

  title={Optically-Pumped Magnetometers for MEG},
  author={Svenja Knappe and Tilmann Sander and Lutz Trahms},
Optically-pumped magnetometers (OPMs) have seen rapid progress over the last decade in terms of performance and technology development. As highly sensitive room-temperature magnetometers they present several advantages over superconducting quantum interference device (SQUID) sensors, such as the possibility for conformal geometries and low-maintenance systems. We review the state of the art and different types of low-field OPMs, as well as the first magnetoencephalography (MEG) demonstrations… CONTINUE READING
