Description
| - We used anisotropic magnetoresistors (AMR's) 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 detection ferromagnetic materials as well as diamagnetic metals. The sensors are specially arranged to suppress the large AC-excitation field, so the mine detector senses both DC and AC field gradient responses of the object of interest. Being limited by the sensor noise of 214 pTrms/sqrtHz at 1 kHz, we were able to detect an 50 mm x 50 mm x 1.5 mm aluminum test object in a 20 cm-depth using a 300uT, 1kHz excitation field.
