This paper proposes a method to measure distribution of refractive index for X-rays. Spatial differentiation of phase of the X-ray transmitted through an object is detected using an X-ray shearing interferometer. From such data for different transmission directions we can reconstruct refractive index distribution inside the object using a modified algorithm for computer tomography. Reconstruction experiment is made with plastics as objects.
