摘要： The pulsed pump magnetometer (PPM) is a new type of magnetometer with much higher dynamic range, linearity, and sensitivity than all other types of magnetometers. These features allow more faithful subtracting and cancelling sources of magnetic noise, enabling high quality biomagnetic measurements. Using an array of PPM sensors enables high quality measurements of biomagnetic signals even in magnetically noisy, real-world conditions like medical offices. Arrays of PPM sensors improve upon pulsed magnetic gradiometers in providing higher sensitivity per sensor and superior noise rejection through noise decorrelation and covariance modeling. Arrays of PPM sensors enable localization and imaging of biomagnetic sources.
