TLDR
Special phase gratings are described by means of which the red, green, and blue color components of colored objects are generated side by side around the optical axis in the image plane of a lens.Abstract:
Special phase gratings are described by means of which the red, green, and blue color components of colored objects are generated side by side around the optical axis in the image plane of a lens. An analysis of these color separation gratings is given, and theoretical and experimental results for some grating samples are presented.read more

TL;DR: In this article, an exact formulation of the grating diffraction problem without approximations is presented, using a series of fundamental assumptions, which reduces to the various existing approximate theories in the appropriate limits.

Multicolor 3D meta-holography by broadband plasmonic modulation
Xiong Li,Lianwei Chen,Yang Li,Xiaohu Zhang,Mingbo Pu,Zeyu Zhao,Xiaoliang Ma,Yanqin Wang,Minghui Hong,Xiangang Luo +9 more
TL;DR: In this paper, an off-axis illumination method was developed to overcome the cross-talk limitation and achieve multicolor meta-holography with a single type of plasmonic pixel.

Spectral properties of multiorder diffractive lenses
Dean Faklis,G. Michael Morris +1 more
TL;DR: It is shown that blazing the surface-relief diffractive lens for higher diffraction orders enables the design of achromatic and apochromatic singlets and the wavelength-dependent optical transfer function and the associated Strehl ratio are derived for multiorder diffractive lenses.

TL;DR: In this article, a display having a number of pixel elements, each capable of transmitting a predetermined spectral region, is positioned within the near field region of the multilevel optical phase element so as to receive the light dispersed by the multi-level phase element.

Zero-reflectivity high spatial-frequency rectangular-groove dielectric surface-relief gratings.
TL;DR: Using rigorous coupled-wave analysis, high spatial-frequency rectangular-groove surface-relief phase gratings are shown to be capable of exhibiting zero reflectivity, and these corrugated surfaces may act as antireflection coatings in a variety of applications.

Color-encoded focused image holograms.
Michael T. Gale,Karl Knop +1 more
TL;DR: Using frequency encoding leads to a simple, inexpensive optical reader similar to a conventional microfiche reader, which gives colorimetry comparable with that of color television and a measured screen luminous emittance of 190 lx using a standard 150-W projection lamp and x15 magnification.
