Abstract

The techniques of stabilizing and linearizing the output of a fiber-optic magnetometer are analyzed both theoretically and experimentally. Results show that the modified phase sensitivity detection system can eliminate the affects of variations due to laser coupling, polarization mixing efficiency, and magnetic feedback and the affects of hysteresis and irregular magnetostrictive response.
