Paper Abstract

A fiber optic magnetic gradiometer has been successfully configured to detect the cardiac magnetic field. The gradiometer is comprised of a Mach Zehnder interferometer, with extremely thin transducers to allow placement of the sensor very near to the chest of a human subject. The sensor detects the cardiac magnetic field in real time, and demonstrates good fidelity in both the time and frequency domains, with only a low pass filter used for signal processing. To our knowledge, this is the first detection of a biomagnetic signal with an optical sensor.
