Diffraction characteristics of the ring zone plate as a representative of curvilinear zone plates
Pure and Applied Optics: Journal of the European Optical Society Part A, 1998It is shown that curvilinear zone plates can be constructed as phase representatives of plane curvilinear light sources. The ring zone plate is one representative of this type of diffracting optical element. At the same time, it is an optical device which can be used as a lens substitute for ring lenses, especially in the UV region. The diffracted wave

Zone Plates Produced Optically
Applied Optics, 1969The nature of optically produced zone plates is briefly discussed in contrast to the conventional type of Fresnel zone plate. A rather simple method for generating zone plates is described, and some of the experimental results are given.

Supplementary Zones-surrounded Fresnel Zone Plate
JSAP-OSA Joint Symposia 2014 Abstracts, 2014The supplementary zones surround an ordinary Fresnel Zone Plate (FZP) are used to improve the optical resolution at focus. Based on the Fresnel-Kirchhoff diffraction formula, an optimization model is used to design the supplementary zones-included FZP (SZFZP).

Abstract Interferometry gives a precise indication of the relative separation of two coherent sources. If the sources are images produced by an optical system, their positions are controlled by the respective components of the system. Interferometry can therefore be used to measure the relative positions, in three-dimensions, of the optical components.

Zone plates with black focal spots
Applied Optics, 1992Computer-designed linear and circular zone plates are considered that utilize a pi ;-phase jump in order to create destructive interference in the focus. Intensity distributions in the focal plane as well as along the optical axis are calculated for a few examples.

Single-focus spiral zone plates
Optics Letters, 2017We extend the concept of spiral zone plates along the optical axis and define a specific single optical element, termed as single-focus spiral zone plates (SFSZPs), for the generation of a single-focus vortex beam. The key idea is to make the transmittance of the spiral zone plates sinusoidal in the azimuthal direction.

Abstract The phase contribution obtained by the superposition of two tilted wavefronts, one cylindrical and the other plane, is considered in this paper. It is shown that the obtained transmittance is equivalent to the conical lens transmittance. In the particular case, when the superposed wavefronts are collinear, the resulting hologram becomes an ...

Zone Plate Theory Based on Holography
Applied Optics, 1967A series representation developed from holography theory is used to determine the image distances and relative image intensities for three types of zone plates. The effect of nonlinearity in film reproduction on the hologram of a point object and the images produced by this hologram are discussed.
