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.

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.

Design and fabricate freeform holographic optical elements on curved optical surfaces using holographic printing

Optics Letters, 2023
Freeform holographic optical elements (HOEs), due to the high degrees of design freedom, can be used to enhance performance of display systems. In this Letter, we propose a method for designing and fabricating freeform HOEs on curved optical surfaces that can be utilized to implement curved augmented reality (AR) displays.

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 ...
