Phase retrieval in the holographic regime. (a) Hologram. (b) RAAR with support- and maximum-phase constraint. (c) CTF without constraints; parameters: lim1 = 5 × 10−4, lim2 = 1 × 10−2, β/δ = 0. (d) CTF with support- and maximum-phase constraint. Data are supplied in the generators folder and can be loaded via . The scale bar represents 5 µm. Data taken from the work of Bartels et al. (2015). |
