title: X-ray shearing interferometer and generalized grating imaging.
abstract: X-ray shearing interferometers with three gratings are analyzed on the basis of generalized grating imaging theory. The result of this analysis is applied to an already proposed interferometer. The contrast of the imaging fringes in the interferometer is calculated quantitatively. It is also applied to explain the spatial resolution of the image.
