Atomic Magnetometry for Biological Imaging In Earth's Native Terrain (AMBIIENT)
Abstract
The Atomic Magnetometry for Biological Imaging In Earth's Native Terrain (AMBIIENT) program developed a novel magnetic sensor capable of providing high-sensitivity signal measurements in the presence of ambient magnetic fields. The AMBIIENT program exploited novel physical architectures that are resistant to the impact of common noise sources. The AMBIIENT sensor itself detected the gradient of a local magnetic field while subtracting the much larger ambient signal. This capability enabled low-cost, portable, high-sensitivity measurements for in-the-field applications. In addition to medical research and clinical diagnosis, AMBIIENT sensors enabled diverse sensing applications including magnetic gradient navigation, anomaly detection, perimeter monitoring, and ultra-low frequency communications.
