Abstract
The design of a magnetic field sensor system based on clad-etched fiber Bragg grating (FBG) sensors is presented in this chapter. When magnetic field monitoring is performed in electronically harsh environments, conventional measurement systems may not be reliable due, for example, to the effects of high levels of ionizing radiation or electromagnetic fields. Fiber Bragg gratings (FBGs) have features that lend these devices suitable to operate in harsh environments, but an appropriate design of the optoelectronic device is needed in order to work as a magnetic field sensor, since FBGs are natively insensitive to magnetic fields. Using magnetic fluids as sensing materials, FBGs can be used to detect magnetic field.
