Abstract

In this work we investigate how the MPI resolution changes as a function of signal harmonics. Based on a simulation study that models a lock-in measurement of the point spread function we apply our findings to actual measurement data obtained from NIST's MPI instrument. In both cases we show that the image resolution improves by a factor of more than two between the 3rd and 7th harmonic.
