Abstract
A fiber-optic magnetic gradiometer capable of measuring both ac and dc magnetic-field gradients has been designed and demonstrated. An approach using real-time magnetic balancing and trimming has been deployed. A device sensitivity of 0.1 gamma (10-6Oe) per centimeter of sensor head separation for 1 m of magnetically active fiber is achievable.Keywords
