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.
