Color Holographic Wavefront Printing Technique for Realistic Representation

IEEE Transactions on Industrial Informatics, 2016
This paper presents design and implementation of a color wavefront holographic printer. The printer output is a white light viewable volume hologram composed as a two-dimensional (2-D) array of elemental holograms. The three-dimensional (3-D) input data for the printer are encoded as computer generated holograms (CGHs) displayed in succession on an ...

Holographic aspheric gratings printed with aberrant waves

Applied Optics, 1987
In astrophysics, holographic gratings use, as far as possible, spherical grating's surface and printing laser waves. However, to obtain high spectral resolution, aberrations must be corrected up to the fourth degree, which generally requires aspheric surfaces for the grating or the laser waves.

High‐Quality Micropattern Printing by Complex‐Amplitude Modulation Holographic Femtosecond Laser

Advanced Optical Materials
Holographic femtosecond laser printing technology is widely used in the fabrication of micropatterns because of its high efficiency and flexibility. However, speckle noise and energy fluctuations limit the quality of the printed structure. In this study,

Beam-shaped femtosecond laser printing of quasi-capsule-shaped holographic terahertz metasurfaces.

Optics Letters
Terahertz (THz) metasurfaces have opened up a new avenue for the THz wavefront modulation. However, high-efficient and low-cost fabrication of THz metasurfaces remains a great challenge today.

HoloTile: a novel digital holographic light sculpting modality for volumetric 3D printing

OPTO
HoloTile is our novel and recently patent-filed approach [1,2] to obtain very fast reconfigurable and strongly speckle-reduced digital holography. Using HoloTile we have experimentally demonstrated more than 90 % photon-efficient phase-only projected ...

A holographic image printing technique with high resolution

Optics Communications, 1973
Abstract A method is shown to obtain a real image with a large image field and high resolution from an image hologram, which is produced by a large aperture lens with large amount of aberration. The resolution of the reconstructed serial image is estimated to be within the range from 450 to 500 lines/mm in 2 inch diameter image field.
