Holographic printing for generating large-angle freeform holographic optical elements

Optics Letters, 2022
We propose a holographic printing technique for generating highly efficient large-deflection-angle freeform holographic optical elements (HOEs). For industrial device applications, the optical efficiency and deflection angle of HOEs are critical.

Improvement of printing efficiency in holographic stereogram printing with the combination of a field lens and holographic diffuser

Applied Optics, 2018
In this paper, we use a field lens and a holographic diffuser together to improve the printing efficiency of a holographic stereogram printing system based on the effective perspective images' segmentation and mosaicking method. The light rays' regulation function of the field lens and the modulation function of the holographic diffuser are analyzed ...

Progress in the printing techniques of the holographic stereogram

Proceedings of SPIE, 2015
Holographic stereogram display technology is one of the research focuses in three-dimensional (3D) holographic display. Holographic stereogram is essentially to infinitely approach the true 3D object using a sequence of 2D perspective images. In this paper, several holographic printing methods are summarized firstly, including two-steps transfer ...

Holographic beam shaping for volumetric 3D printing

Advanced Fabrication Technologies for Micro/Nano Optics and Photonics XVII
Light-based technologies for 3D printing have recently been developed and are leading the field thanks to their unmatched performance. However, these techniques are still limited to using incoherent light patterning for printing. Here, we present a novel approach that allows us to print using coherent patterns by combining light-beam shaping and ...

Hologram printing for next-generation holographic display

Ultra-High-Definition Imaging Systems, 2018
In this paper, we introduce hologram printing technology. This technology includes the following technologies, computer-generated hologram, hologram printer, duplication, and application-depended technologies. When this technology is applied to static hologram, the media can present static 3D objects more clearly than traditional 3D technologies such ...

Progress in holographic printing technique

Hongwai Yu Jiguang Gongcheng/Infrared and Laser Engineering, 2018
Holographic printing technique can achieve a true three-dimensional display of the scene well. Based on different sources and different recording methods of interference patterns, holographic printing techniques can be classified as synthetic holographic stereogram printing, computer-generated hologram printing, and wavefront printing.

Hybrid Sensors Fabricated by Inkjet Printing and Holographic Patterning

Chemistry of Materials, 2015
Inkjet printing and patterning strategies have been developed for fabrication of hybrid holographic sensors using zeolite nanocrystals on glass-supported photopolymers. The flexibility of the proposed techniques was demonstrated by fabrication and characterization of two types of holographic sensors.

Digital holographic printing using pulsed RGB lasers

Optical Engineering, 2011
A one-step digital holographic printing system based on RGB pulsed-laser technology is described. The system is capable of writing full-color composite digital reflection holograms and composite digital holographic optical elements up to a size of 1.0 m×1.5 m at hogel sizes ranging from 0.4 to 2 mm. We also show how the same pulsed-laser technology may
