摘要：
Using full-tensor gradiometers has various advantages over simplified uniaxial gradiometers or even scalar measurements. The full-tensor information is used mainly in geophysical prospecting and in security/military applications. Usually, three or more triaxial probes are combined for the full-tensor measurement. However, in our new design we combined 10 small (20-mm) fluxgate sensors operating in feedback compensated mode into one compact head in the form of 46-mm cube. The sensors are multiplexed in order to save on electronics complexity and power consumption.
