Figure 7
A 2D slice (same index as Fig. 6) of the alien detection mask for the Bragg peak after 0, 200 and 400 iterations of phase retrieval. The mask, initially covering only the brightest parts of the alien, grows as the reconstruction reaches a consensus on the merits of each measured voxel. In these tests, the mask typically stabilized after approximately 400 iterations and showed little change thereafter. |
