Two-dimensional grating interferometric imaging of a near object by computed tomography

The Fourier coefficients of a near object can be obtained by analyzing the interference pattern in an achromatic grating interferometer. Using the projection slice theorem, the Fourier plane can be filled and the spatial irradiance distribution of a 2-D incoherent object can be reconstructed.
