COMBINED ELECTRON PARAMAGNETIC RESONANCE (EPR) AND NUCLEAR MAGNETIC RESONANCE (NMR) MAGNETOMETER SYSTEM |
摘要 |
One embodiment of the invention includes a magnetometer system. The system includes a sensor cell comprising alkali metal particles and a probe laser configured to provide a probe beam through the sensor cell. The system also includes a detection system configured to implement nuclear magnetic resonance (NMR) detection of a vector magnitude of an external magnetic field in a first of three orthogonal axes based on characteristics of the probe beam passing through the sensor cell and to implement electron paramagnetic resonance (EPR) detection of a vector magnitude of the external magnetic field in a second and a third of the three orthogonal axes based on the characteristics of the probe beam passing through the sensor cell. The system further includes a controller configured to calculate a scalar magnitude of the external magnetic field based on the magnitude of the external magnetic field in each of the three orthogonal axes. |

1. A magnetometer system comprising:
a sensor cell comprising alkali metal particles; a probe laser configured to provide a probe beam through the sensor cell; a detection system configured to implement nuclear magnetic resonance (NMR) detection of a vector magnitude of an external magnetic field in a first of three orthogonal axes based on characteristics of the probe beam passing through the sensor cell and to implement electron paramagnetic resonance (EPR) detection of a vector magnitude of the external magnetic field in a second and a third of the three orthogonal axes based on the characteristics of the probe beam passing through the sensor cell; and a controller configured to calculate a scalar magnitude of the external magnetic field based on the detected magnitude of the external magnetic field in each of the three orthogonal axes.
