The recently developed magnetic encoding beam microscopy approach to imaging with neutral atomic beams has a spatial resolution that is limited by the spread of velocities within the beam. Here we present a solution for overcoming this restriction which is based on adding a homogeneous magnetic field and resolving both the spatial resolution and the de Broglie wavelength of the particles using sequential Fourier transforms. Numerical simulations are used to demonstrate the enhanced resolution obtained with this approach, and how features which were lost in the spatial reconstruction due to the spread of velocities can be recovered. Wavelength/velocity resolved profiles that were reconstructed from experimental data are presented, demonstrating how the scheme can be applied in practice.
