A novel optical field probe is described for the precision measurement of high magnetic fields. The advantages over traditional field probes are two-fold. First, there is no electromagnetic interference with the other parts of the MRI system such as the RF coil. Secondly, the setup allows for a continuous and long readout of the magnetic field during an MRI sequence, where traditional NMR probes typically operate in a pulsed mode.
