In this work,we make a theoretical analysis of X_ray grating phase contrast imaging (XGPCI) and give an equation to show the relationship between the transmittance and the relative shift of the two gratings,which was named as the shift curve.According to this equation,we develop a new method to retrieve phase information from the experimental data in theory.Finally,we analyze the influence of the experimental setup to the resolution of the image.
