AMR Gradiometer for Mine Detection
(Elsevier Science, 2012)
Anisotropic magnetoresistors (AMRs) are used to build an advanced mine detector. The sensing head involves a gradiometric pair of AMR sensors and a continuous-wave driven excitation coil, so the gradiometer is capable of ...
Experimental Comparison of the Low-Frequency Noise of Small-Size Magnetic Sensors
(IEEE, 2017)
Small-size ac magnetic-field sensors are used for nondestructive testing (NDT), magnetic particle detection, and other applications, which require high spatial resolution. Up to now, inductive coils dominated this area, ...
