Apparatus and method for lower magnetometer drift with increased accuracy

摘要

The present disclosure relates to apparatuses and methods for stimulating a magneto-optical defect material with defect centers in a magnetic detection system using a stimulation process to significantly increase magnetic sensitivity of the detection system. The system utilizes a Ramsey pulse sequence pair or a shifted magnetometry adapted cancellation (SMAC) pair to detect and measure the magnetic field acting on the system. Utilizing a pair of magnetic measurements that are approximately in quadrature improves the dynamic range and accuracy of the magnetic detection.
