Figure 3
Amorphous Au particle. (a) Achievable resolution for various photon statistics, where the solid line is the theoretical model described by equation (2)[link] and circles are reconstructions using CXDI from simulated photon statistics. The horizontal dashed line indicates the pixel size below which the current simulations cannot reach, and the dashed line which follows much of the theoretical curve indicates the expected [\delta x^{\,{-5}}] fall-off for a uniform particle. To show local resolution, a subset of recovered atomic positions at the center (b)–(e) and edge (f)–(k) of the particle are shown, where atomic position ME and MAE (a) are also given. The actual atomic position at the center (b) and edge (f) of the particle are fully recovered by 1.5 × 1017 photons µm−2 (c) and (g). At 1017 photons µm−2 (d) and (h), all but one atom matches the known solution for the center and edge, respectively. Finally, at 6 × 1016 photons µm−2 (e) and (k) a large number of atomic positions are incorrect.
