Abstract
Magnetometers disposed as magnetostrictive segments on optical fiber elems are incorporated in multiple order gradiometers to reduce the size, weight and cost thereof. In the preferred embodiments, such reductions are greatly enhanced by consolidating a plurality of magnetometers on individual optical fiber elements, which also serves to decrease the number of devices associated with the magnetometers in the multiple order gradiometers.
