Numerical Analysis of Antiphase Domain Boundaries in a FeAl Alloy Using X-Ray Bragg Coherent Diffractive Imaging
TL;DR: In this paper, the modulus homogenization (MH) constraint was used to obtain a reliable APD reconstruction in coherent X-ray diffractive imaging (CDI) images.
The influence of strain on image reconstruction in Bragg coherent X-ray diffraction imaging and ptychography.
TL;DR: In this paper, the phase maps of objects with strong step-like phase changes are more precisely retrieved than the corresponding modulus values, by employing a modulus homogenization (MH) constraint.
