Abstract
We describe the operation and results of our first generation zero field optically pumped magnetometer (OPM) developed for biomedical applications. The OPM technology is one of the most promising non-cryogenic candidates to replace superconducting quantum interference device (SQUID) magnetometers in key areas of biomagnetism. The first-generation sensors are designed to transition OPM technology from a physics laboratory to researchers in the medical community. The laser and optical components are tightly integrated inside the sensor package, and the sensor is tethered to a dedicated electronics signal processing unit that enables automated and standalone operation inside a magnetically shielded room.
