Development of a Micro-Fabricated Total-Field Magnetometer

摘要

Magnetometers are one of the basic instruments used for the detection and discrimination of unexploded ordnance (UXO). Cesium vapor atomic magnetometers are commonly used since their readings are independent of the orientation of the sensor, which eliminates the noise problems due to rotation or even vibration of other types of sensors. In order to better discriminate UXO from clutter or scrap, a high spatial density of readings is desirable. In order to efficiently make such measurements, and to position such measurements accurately, arrays of sensing elements would be highly desirable. However, existing cesium vapor sensors are extremely large and consume a lot of power.
