Fig. 5: Comparison of simulated 2d magnetic encoding signals for different types of density distributions.
From: Neutral beam microscopy with a reciprocal space approach using magnetic beam spin encoding
a, b The original input spatial distributions \({{\rho }\left(x,y\right)}_{{\rm {{smooth}}}}\) and \({{\rho }\left(x,y\right)}_{{{\rm {sharp}}}}\) respectively. c, d The corresponding calculated signals \(S\left({k}_{x},{k}_{y}\right)\) demonstrating how smooth/wide features in real space appear as signals concentrated near the origin of \({k}_{x},{k}_{y}\), whereas sharp/narrow features in real space extend throughout the \({k}_{x},{k}_{y}\) space. For clarity, just the real part of \({S}\left({k}_{x},{k}_{y}\right)\) is shown. e, f show the \({S}\left({k}_{x},{k}_{y}\right)\) plotted above them after adding random noise to mimic their appearance in the presence of shot noise in an experiment.
