MAGNETIC DETECTION SYSTEM FOR DEVICE DETECTION, CHARACTERIZATION, AND MONITORING

Abstract:

A system for magnetic detection includes a magneto-optical defect center sensor and an analytics system. The magneto-optical defect center sensor has a magneto-optical defect center material comprising at least one magneto-optical defect center that emits an optical signal when excited by an excitation light. The analytics system can be configured to receive a measured magnetic field measured by the magneto-optical defect center sensor and identify a device generating at least a portion of the measured magnetic field based on a plurality of nominal magnetic signatures. In some instances, the analytics system can determine a failure of a component of a device or output data indicative of performance of the device. In some instances, the measured magnetic field can be a vector.
