Hard X-ray Microscopy Enhanced by Coherent Image Reconstruction.

The article focuses on designing of Fresnel zone plate optics for photon energies and demonstrates X-ray holography limited by the numerical aperture of probing beam. Topics discussed include attempts of x-ray microscopes based on concept of optical imaging system, propagation of x-ray wave fields using finite-differences propagation method, and showing holographic X-ray imaging based on illumination of cone-beam.
