Abstract

A system that employs a stainless steel wire mesh to produce a high-contrast structured illumination pattern reduces the need for source coherence and complex alignments in x-ray phase imaging. Phase is reconstructed from distortions in this pattern due to phase-based x-ray deflection. A computational model of this system has been developed. Accurately assessing detector performance significantly improves the accuracy of the phase reconstruction.
