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: A system comprising: two or more tracking sensors that are configured to provide pose information, wherein the two or more tracking sensors include: a first tracking sensor configured to provide a reference coordinate system; and a second tracking sensor that resides in the reference coordinate system relative to the first tracking sensor; one or more segments of optical fiber affixed to the second tracking sensor, wherein the one or more segments of optical fiber are tracked relative to the second tracking sensor; an interrogator that is configured to read measurements from the one or more segments of optical fiber; and a computing device configured to execute an algorithmic method on data from the one or more segments of optical fiber, wherein measurements taken from the one or more segments of optical fiber are placed in the context of pose information from the two or more tracking sensors.
