Magneto-optic coupling coefficient for fiber interferometric sensors.
The magneto-optic sensitivity (coupling coefficient) has been measured as a function of frequency from 15 Hz to 3 kHz for a fiber interferometer incorporating a magnetostrictive nickel toroid. The frequency response of the coupling coefficient was found to be essentially flat from 15 Hz to approximately 600 Hz, where eddy-current losses become significant for the sample tested.
