A Scalable Large‐Area Fabrication Strategy for Transparent Polymeric Encapsulated Metagratings
Nanophotonics, Volume 15, Issue 14, 27 July 2026.Transparent encapsulated polymeric guided‐mode resonant metagratings are fabricated by thermal nanoimprint lithography and experimentally validated through structural and optical characterization. The scalable fabrication strategy enables selective RGB reflection and provides a practical route toward large‐area augmented reality and wavelength ...

Computer-generated rainbow holograms
Applied Optics, 1984A technique is described for synthetic generation of rainbow holograms. Minimization of the space–bandwidth product is discussed considering the reconstruction geometry. It is shown how the flexibility of computer-generated holography can be used to make compromises and solve particular problems peculiar to display applications. Artificially introduced

Adaptive Computation of Computer-Generated Holograms
Advances in Imaging, 2008Regular Effective Hologram Regions (EHRs) for object subspaces are pre-calculated. Object points are categorized online and the corresponding EHRs are used for hologram computation. The use of EHRs increases computational speed and benefits reconstruction quality.

Disk hologram made from a computer-generated hologram
Applied Optics, 2009We have been investigating disk holograms made from a computer-generated hologram (CGH). Since a general flat format hologram has a limited viewable area, we usually cannot see the other side of the reconstructed object. Therefore, we propose a computer-generated cylindrical hologram (CGCH) to obtain a hologram with a 360 deg viewable area.

Binary computer-generated holograms
Applied Optics, 1979Binary computer-generated holograms are similar to interferograms with fringe patterns hardclipped by a photographic process. Therefore the fringe locations in the binary hologram can be determined by solving a grating equation. However, there are two difficulties in using this approach to make binary Fourier transform holograms.

Computer-generated holograms for geometric transformations
Applied Optics, 1984Theory and experiments in the area of computer-generated holograms for geometric transformations are presented. Geometric transform holograms are divided into two categories: (1) those which have a continuous fringe structure, and (2) those which consist of a set of discrete subholograms.

Computer-generated double-phase holograms
Applied Optics, 1978A method of computer generating binary holograms based on the decomposition of a complex value into two phase quantities is described. Each Fourier transform cell is divided into subcells, and phase quantities are encoded by the detour phase technique. Noise due to the displacement of the subcells and the phase coding is discussed.

Rotational control of computer generated holograms
Optics Letters, 2017We develop a basis for three-dimensional rotation of arbitrary light fields created by computer generated holograms. By adding an extra phase function into the kinoform, any light field or holographic image can be tilted in the focal plane with minimized distortion.
