Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>An adaptive orientation reconstruction algorithm is developed for near‐field high‐energy X‐ray diffraction microscopy. When combined with a spatially adaptive extension the algorithm results in a factor of 10–1000 speed‐up over the existing forward modeling reconstruction method while preserving most of the spatial and orientation resolution characteristics. Tests of the reconstruction code based on simulated structures and real data on a complex microstructure are presented. Simulated structures include intra‐granular orientation gradients and noisy detector images. It is shown that resolution in both real space and orientation space degrades gracefully as complexity and detector noise increase.</p> </abstract>
