Measurement and origin of magnetostrictive noise limitation in magnetic fiber-optic sensors.
Fiber-optic magnetic sensors based on magnetostriction yield l/f-type noise, which has typically been limiting the sensors' resolution at frequencies below 1 Hz. To study the origin of this noise, we devised a new experimental technique that discriminates between the transducer self-noise and various other noise sources and determines under which conditions the limiting noise source is the material's self-noise.
