{"product_id":"jixi-lu-optically-pumped-magnetometer-and-its-application-9783725846931","title":"Optically Pumped Magnetometer and Its Application","description":"The optically pumped magnetometer (OPM) is a class of atomic devices that rely on the measurement of Larmor precession of an atomic spin ensemble in a magnetic field. They need the specific frequency light to complete the pumping and detection process. OPMs typically work under the Earth's magnetic field or a limited field. When operating in near-zero field, they can realize the spin-exchange relaxation-free (SERF) regime, thereby promoting a substantial increase in sensitivity. At present, OPMs have been widely used in magnetoencephalography, magnetocardiography, geomagnetic detection, and inertia measurement (comagnetometer). There are a large number of researchers engaged in the study of relevant mechanisms, devices, technologies, and applications. More importantly, supported by MEMS technology and micro\/nano optics, OPMs have the potential to move toward chip-scale sensors. This special issue contains some latest developments in OPMs and related areas. We hope the reprint can provide valuable references for researchers in the related field.","brand":"MDPI AG","offers":[{"title":"Default Title","offer_id":53711824617814,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9783725846931_1.jpg?v=1778873406","url":"https:\/\/www.momoxbooks.com\/products\/jixi-lu-optically-pumped-magnetometer-and-its-application-9783725846931","provider":"momoxbooks","version":"1.0","type":"link"}
