(a) Au hemispherical crystal (500 nm radius) reconstructed in three dimensions using the kinematical model and viewed along the axis perpendicular to the diffraction plane (defined by the incident and diffracted directions). The Au 002 reflection at 7.5 keV is assumed. (b) Optical path difference along the incident and diffracted beam directions inside the crystal, which determines the attenuation and the amount of phase shift the X-ray wave experiences as a result of a non-unity complex refractive index. (c) and (d) are the cross-sectional views of the reconstructed amplitude and phase in the central diffraction plane obtained from the K-M (Δn = 0) data set, respectively. (e) and (f) are the reconstructed amplitude and phase in the same plane obtained from the K-M (Δn [\ne] 0) data set, and (g) and (h) are the corresponding images after absorption/refraction correction. (i) and (j) are the reconstructed amplitude and phase obtained from the D-M data set, and (k) and (l) are the corresponding images after absorption/refraction correction.
