Description
Abstract:
Distributed sensing is an unique ability of optical fiber sensors, which enables to continuously map the physical field of interest (temperature, strain, magnetic field, etc.) along the fiber. Distributed fiber optic sensors are based on the scattering processes that take place in silica fibers; depending on the exploited technology, spatial resolutions ranging from few centimeters to some meters can be achieved over fiber lengths up to several tens of kilometers. After an introduction about the general principles of distributed fiber optic sensing and a survey of the current state of art, the seminar will focus on a recently developed polarization-sensitive technique that allows mapping intense magnetic fields in the area spanned by the optical fiber.
