Diffraction characteristics of square zone plates
TLDR
In this paper, the diffraction wave field and irradiance distribution for the case of Fresnel diffraction of a square zone plate were studied, and the authors showed that the irradiance distributions of the diffracted wave field were similar to those of the irradiated wave field.Abstract:

Diffractive ophthalmic lens for correcting astigmatism
TL;DR: In this article, an artificial eye lens such as a contact lens or intra-ocular lens corrects astigmatism by two sets of substantially linear parallel zones arranged to diffract light predominantly into one order at one orientation.
Journal ArticleDOI
X-ray microscopy
TL;DR: The main advances have been in intense sources, principally synchrotron radiation and plasma sources and in X-ray optical components such as grazing incidence reflectors, multilayer mirrors and zone plates as mentioned in this paper.

Fresnel Zone Plate for Optical Image Formation Using Extreme Ultraviolet and Soft X Radiation
TL;DR: In this article, a new Fresnel zone plate was constructed which can focus ultraviolet radiation of any wavelength down to the soft x-ray region, using a set of thin circular gold bands made self supporting by radial struts.

On the Theory of Diffraction by Concentric Arrays of Ring-Shaped Apertures
TL;DR: In this article, the authors extended Lommel's problem to the case of a concentric array of ring-shaped apertures with arbitrary distribution of circle radii, and derived new expansions in complex power series for the amplitude diffracted by the annular array.

Variations on the Fresnel Zone Plate
TL;DR: In this paper, the effects of contrast in the Fresnel zone plate on the amplitude in the focal point due to a normally incident plane wave are obtained by direct evaluation of the FK diffraction integral.

Diffraction Characteristics of a Linear Zone Plate
TL;DR: In this paper, the focusing, resolving, and diffracting properties of a linear zone plate in the neighborhood of the principal positive focus were examined theoretically and experimentally using both elementary and Kirchhoff diffraction theory.
