The subject of X-ray microscopy (high-resolution X-ray imaging of general nonperiodic structures), an area in which much progress has been made in recent years, is reviewed. The main techniques are briefly described. Achievable performance levels, which for many years were highly speculative, can now be understood with fair accuracy in terms of basic X-

SummaryThe science of wave‐field phase retrieval and phase measurement is sufficiently mature to permit the routine reconstruction, over a given plane, of the complex wave‐function associated with certain coherent forward‐propagating scalar wave‐fields.

Diffraction Microscopy with X-Rays
Nature, 1952IN a recent communication, A. V. Baez1 predicts the practical resolution obtainable by diffraction microscopy using X-rays. His prediction is based on the required conditions for making the hologram. Similar derivations were described by us at the International Conference on Electron Microscopy in Paris, September 1950, though unfortunately we are ...

Annual Review of Condensed Matter Physics, 2010
X-ray diffraction phenomena have been used for decades to study matter at the nanometer and subnanometer scales. X-ray diffraction microscopy uses the far-field scattering of coherent X-rays to form the 2D or 3D image of a scattering object in a way that resembles crystallography.

Science, 1979
Soft x-ray contact microscopy, utilizing single-shot exposures of ∼60 nanoseconds duration in polymethyl methacrylate, has been realized with a resolution of 300 angstroms. The radiation spectrum is intense in the "window" between 23 and 44 angstroms where water is transparent compared to biological materials, and therefore permits viewing of wet ...

Owing to the short wavelengths of X-radiation X-ray microscopes allow higher resolution than optical microscopes. In contrast to electron microscopes, X-radiation can be used to study relatively thick aqueous specimens in their natural environment. X-ray microscopes require intense X-radiation, which is best provided by electron storage rings, as well ...

X-Ray Microscopy of the Prostate Gland
Journal of Urology, 1988Summary— A technique is described for investigating the internal structure of the prostate gland (including calcification) by projection X‐ray microscopy (microradiography). The results show that the technique can be used in conjunction with the corresponding histological ...

Trends in Cell Biology, 1999
Soft x-ray microscopes are beginning to provide information to complement that obtained from optical and electron microscopy. Soft x-ray microscopy can deliver 30-nm resolution images of hydrated cells up to approximately 10 microns thick, and efforts towards obtaining higher resolution are under way. Although living specimens cannot be studied readily
