Mechanical Error Analysis of Grating-Based X-Ray Phase-Contrast Imaging

Grating-based x-ray phase-contrast imaging has attracted increasing attention in recent decades. Regarding practical applications, efforts have been made to develop information extraction methods. In this work, we report quantitative descriptions of grating-based phase-contrast imaging for the mechanical error of different combination information using angular signal radiography. Results show the quality of image in different combination information of grating-based x-ray phase-contrast imaging. Our conclusions provide directions to use grating interferometer for specific and targeted applications.
