Optically-Modulated Miniature Magnetometer (OMMM)

Completed Technology Project

Project Introduction

Design, fabricate, and calibrate a compact helium magnetometer for high-accuracy measurements of Earth’s magnetic field
Provide vector and scalar measurements from a single instrument
Utilize scalar measurements to self-calibrate the vector component measurements
Intended for surface, sub-orbital, and orbital platforms
Achieve superior calibrated vector accuracy (±1 nT per component) not possible with fluxgate magnetometers
