Abstract
Removing diffraction effects in a tomographic image includes: obtaining an empirical image of a sample; producing an initial wave at a radiation source; forward propagating the initial wave from the radiation source toward a detector; receiving by a sample the initial wave; forward propagating the initial wave through the sample and accumulating phase and amplitude information to produce a phase accumulated wave; back propagating the phase accumulated wave; and forward propagating the phase accumulated wavewhile treating Fresnel diffraction, such that the empirical image is reconstructed by projections and diffraction via maximum likelihood, a Bayesian prior probability distribution, and a Fresnel propagator.
