Paper Abstract

A balancing procedure for a fiber optic magnetic gradiometer is presented. The gradiometer is a Mach-Zehnder interferometer with both arms configured as measurement arms. The procedure describes the nulling of DC environmental fields at each of the transducers without the difficulties associated with hysteresis when a previously nulled transducer is re-energized. The use of an additional AC signal at a frequency small compared with the dither is discussed, and balancing data are presented demonstrating the procedure.
