Paper Abstract

A novel technique is presented that allows independent simultaneous remote measurement of temperature and magnetic field, and therefore electric current. This technique is based on interferometric phase measurement of temperature combined with magnetic field induced visibility modulation of the interferometric fringes. The technique is demonstrated using a paramagnetic FR-5 glass sensing element, and it is shown that the measurement of temperature enables compensation of the temperature-dependent Verdet constant.
