Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for tracking fiber optic shaping. In some implementations, a server obtains optical signals reflected through a fiber, the fiber comprising one or more embedded sensors and a nano-magnetometer embedded at a distal location of the fiber. The server determines a frequency shift of each of the reflected optical signals, the frequency shift imparted on the reflected optical signals by the one or more embedded sensors. The server determines a phase shift of each of the reflected optical signals, the phase shift imparted on the reflected optical signals by the nano-magnetometer. The server determines characteristics of the fiber using the determined frequency and the phase shift of each of the reflected optical signals, the characteristics comprises a shape of the fiber and a location of the fiber in relation to an external reference.

Abstract: 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.
