BCDI phase retrieval. (a) A comparison between reconstructed object phases using data acquired with (top) the Maxipix detector (1 s exposure) and (bottom) the CITIUS detector (0.1152 s exposure). (b) The quality of phase retrieval is compared by quantifying the edge resolution of the reconstructed nanoparticles. Time refers to the acquisition time of each point in the rocking curve. Resolution is estimated as the width of the first derivative of the particle amplitude at each edge, being averaged across the x, y and z directions. (c) Slices across the y axis of the reconstructed objects. The amplitude, phase and out-of-plane strain of the Pt particles are reconstructed using reduced data frames (from the CITIUS detector) to simulate reduced acquisition times. The quality of the reconstructions remains high above 5 ms per point.
