Fig. 1: Computational graph for coherent X-ray dynamical diffraction.
From: Unveiling nano-scale crystal deformation using coherent X-ray dynamical diffraction
a Basic geometry of a BCDI experiment. b Schematic of coherent X-ray diffraction from a crystal in BCDI experiments. c Computational graph for the reconstruction. The forward path marked by solid arrows predicts the diffraction pattern measured by the X-ray detector and evaluates the loss function. The backward path marked by dashed arrows computes the gradients with respect to each optimizable variable.
