  Recent improvements to spatial resolution in angle-resolved photo-emission
spectroscopy (ARPES) have made it common to perform measurements with a very
brief dwell time, for the purpose of mapping the spectral function over large
surface regions. However, rapid measurement modalities can suffer a grid-like
intensity modulation due to a wire mesh that is typically placed in front of
the ARPES detector to block stray electrons. Here, we explore Fourier-based
methods that can effectively remove this artifact, and improve the quality of
ARPES images obtained in rapid scanning modes. An open source software package
is provided containing implementations of demonstrated algorithms.
