Non-iterative solution of the phase retrieval problem using a single diffraction measurement
Non-iterative solution of the phase retrieval problem using a single diffraction measurement is a scholarly work, published in 2008 in ''Optics Express''. The main subjects of the publication include Phase retrieval, cryogenic electron microscopy, digital image processing, optics, sample, phase, ptychography, Phase-contrast imaging, radiography, image, X-ray absorption spectroscopy, algorithm, physics, iterative numerical method, computer science, Phase problem, Fresnel diffraction, Coherent diffraction imaging, iterative reconstruction, and diffraction. The authors employ methods borrowed from density functional theory to show that an image can be recovered in a single non-iterative step for a finite sample subject to phase-curved illumination.
