We used 204 gradiometer
signals among the 306 channels for data analysis because the characteristics of the gradiometer
and magnetometer sensors differ and the signal-to-noise ratio (SNR) of the gradiometers
is better than that of the magnetometers .
Within the same area, sensitive gradiometers detected magnetic signs of cooking hearths and pot fragments.
That's why he and his colleagues sought permission from the American Battle Monuments Commission to investigate the site with radar carts, metal detectors, and gradiometers.
The MEG system had 102 triple-sensor elements, each comprising two orthogonal planar gradiometers
and one magnetometer.
Methods: Magnetocardiographic mapping is performed with a 36-channel unshielded mapping system, based on DC-SQUID sensors coupled to second-order axial gradiometers
(pick-up coil 19 mm and 55-70 mm baselines; sensitivity of 20 fT/[square root of Hz] in above 1 Hz), as part of the electrophysiologic investigation protocol, tailored to the diagnostic need of each arrhythmic patient.
Researchers around the world are also pursuing the promise of quantum improvements for other instruments, including gyroscopes used in navigation systems, atomic clocks, and gravity-measuring devices, or gradiometers
, that guide oil exploration and geophysical research.
is manufacturing three microprocessor-controlled fluxgate gradiometers
The Navy already uses precision-machined electromechanical gravity gradiometers
to help submarines navigate without noisy sonar.
This increased sensitivity may lead to new technologies, such as ultra-sensitive gravity gradiometers
for the detection of mineral reserves, as well as important applications to fundamental physics, such as tests of fundamental theories beyond the standard model.
