From: High-precision speckle-tracking X-ray imaging with adaptive subset size choices
Simulated sample: the (a) horizontal and (b) vertical phase gradients and (c) the dark field for the subset size of 7 × 7; the (d) horizontal and (e) vertical phase gradients and (f) dark field for the subset size of 25 × 25; the (g) horizontal and (h) vertical phase gradients and (i) dark field for the ASC; (j) speckle patterns with a sample; the (k) horizontal and (l) vertical side length of the subset.
