Double-resonance OPM operation is well suited to unshielded magnetometry, due to high sensor dynamic range. However, sensor response is highly anisotropic with variation in the orientation of the magnetic field. We present data quantifying these effects and discuss implications for the design of practical sensors.","authors_text":"Aidan S. Arnold, Carolyn O'Dwyer, Erling Riis, Iain C. Chalmers, Paul F.
