Nodal-line dynamics via exact polynomial solutions for coherent waves traversing aberrated imaging systems
David M. Paganin, Mario A. Beltran, Timothy C. Petersen
We obtain exact polynomial solutions for two-dimensional coherent complex scalar fields propagating through arbitrary aberrated shift-invariant linear imaging systems. These are us…
Phase-and-amplitude recovery from a single phase contrast image using partially spatially coherent X-ray radiation
Mario A. Beltran, David M. Paganin, Daniele Pelliccia
A simple method of phase-and-amplitude extraction is derived that corrects for image blurring induced by partially spatially coherent incident illumination using only a single inte…
Propagation of fully-coherent and partially-coherent complex scalar fields in aberration space
David M. Paganin, Timothy C. Petersen, Mario A. Beltran
We consider the propagation of both fully coherent and partially coherent complex scalar fields, through linear shift-invariant imaging systems. The state of such imaging systems i…
On the "unreasonable" effectiveness of Transport of Intensity imaging and optical deconvolution
T. E. Gureyev, Ya. I. Nesterets, A. Kozlov +2
The effectiveness of reconstructive imaging using the Homogeneous Transport of Intensity equation may be regarded as "unreasonable", because it has been shown to significantly incr…
On the van Cittert - Zernike theorem for intensity correlations and its applications
Timur E. Gureyev, Alexander Kozlov, David M. Paganin +3
A reciprocal relationship between the autocovariance of the light intensity in the source plane and in the far-field detector plane is presented in a form analogous to the classica…
