Visible cone-beam tomography with a lensless interferometric camera

Digital processing of optical coherence functions can reconstruct three-dim ensional objects illuminated by incoherent light. It is shown that Fourier analysis of the mutual intensity of the field produces projections that are mathematically identical to the projections of x-ray cone-beam tomography. A lensless interferometric camera that captures planes of mutual intensity data is described and used to reconstruct an incoherently illuminated visi ble object in three dimensions.
