Robust Compensation of Magnetic Field Perturbations for Localized Spectroscopy Applications

caixia Fu¹, GuoBin Li¹

In this abstract, factors affecting the results of the sideband cancellation in opposite-gradient acquisition scheme are analyzed. Based on this scheme, a robust and simple compensation method is presented, in which optimized cancellation is achieved by carrying out eddy-current phase correction for positive-gradient and negative-gradient acquisitions respectively.
