A fiber-optic magnetic gradiometer
Journal of Lightwave Technology, 1983A 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.

Differential readout for a magnetic gradiometer
Sensors and Actuators A: Physical, 2009Abstract A magnetic gradiometer system being developed by the authors uses a vibrating string as its sensing element. The next generation of sensor will use a wide ribbon instead of a string. In order to precisely measure the displacement of the ribbon we have designed a new differential capacitive readout with displacement noise below 1 0 −

Magnetic gradiometer with self compensation of offset drift
2016 IEEE SENSORS, 2016In this paper we present a magnetic gradiometer based on a single core orthogonal fluxgate in fundamental mode. Contrarily to similar gradiometers based on detached sensor heads the use of a single core strongly reduces the offset instability of the output.

The Magnetic Field Gradiometer
1983Abstract : This report has two principal goals. First, to present a general review of magnetic field gradiometers and, second, to provide new data concerning these gradiometers, including new information about their response to magnetic dipole fields.

Use of a superconductive magnetic gradiometer near magnetic objects
Journal of Applied Physics, 1983We present a technique for orienting a superconductive magnetic gradiometer, formed by two coplanar pickup loops, to suppress gradient fluctuations originating from nearby magnetic objects. We developed the technique to quiet fluctuations coming from the steel structure of an oceanographic research tower that impressed gradients of about 200 nT/m at ...

GMSPPF for Magnetic Ellipsoid Tracking with a Magnetic Gradiometer Tensor
Advanced Materials Research, 2013Magnetic ellipsoid tracking problem is characterized by high nonlinearity. In this study, the determination of target position, magnetic moment, and velocity is formulated as a Bayesian estimation problem for dynamic systems, a recursive approach is proposed to estimate the trajectory and magnetic moment component of the target using data collected ...

Magnetic gradiometer for underwater detection applications
SPIE Proceedings, 2006We have designed and constructed a magnetic gradiometer for underwater mine detection, location and tracking. The United States Naval Surface Warfare Center (NSWC PC) in Panama City, FL has conducted sea tests of the system using an unmanned underwater vehicle (UUV).
