Abstract
There is provided a system () for magnetic field detection, comprising a fiber optic interrogator () adapted to interrogate a first length of optical fiber () with interrogating radiation, detect radiation backscattered from said optical fiber and analyze said detected radiation to provide distributed sensing indicative of mechanical disturbances of said optical, wherein the optic fiber is mechanically coupled to a material whose dimensions vary dependent on applied magnetic field. Changes in dimensions of the optic fiber as can be detected by virtue of changes in back-scattering of light from said fiber using the principles of fiber optic distributed acoustic sensing.
