Abstract

We have developed a field-deployable vector magnetometer using a small rubidium vapor cell, which is capable of measuring the magnitude and direction of the earth's magnetic field with high accuracy and sensitivity. The magnetometer measures Larmor precession of rubidium atoms using the phenomenon, called synchronous coherent population trapping (SCPT). This gives the advantage of producing a high contrast and narrow linewidth resonance needed for measuring the magnetic field with high accuracy and sensitivity. The magnetometer exhibits sub-nT/√Hz sensitivities in measuring the field components along the three directions.
