Abstract

See full text

The present disclosure provides a cuboid magnetometer with high fluorescence collection efficiency, used for cardiac magnetic field measurement, and based on nitrogen-vacancy (NV) centers in diamond, and a cardiac magnetic field measurement system. The cardiac magnetic field measurement system includes a magnetic shielding chamber, a non-magnetic bed, an array probe for cardiac magnetic field measurement, a three-axis displacement platform, a high-speed data collection card, a fiber laser source, a microwave source, and a computer. The array probe for cardiac magnetic field measurement includes a non-magnetic shell, a stepping motor, a porous rotary fiber coupling apparatus, a fiber bundle set, a special photodetector (PD) set, a filter set, a ring-shaped antenna, and special diamond.
