Photonics, 2022 In near-eye displays (NEDs), issues such as weight, heat, and power consumption mean that the rendering and computing power is usually insufficient. Due to this limitation, algorithms need to be further improved for the rapid generation of holograms.

Resolution Enhancement of Spherical Wave-Based Holographic Stereogram with Large Depth Range
Applied Sciences, 2021 The resolution-priority holographic stereogram uses spherical waves focusing on the central depth plane (CDP) to reconstruct 3D images. The image resolution near the CDP can be easily enhanced by modifying three parameters: the capturing depth, the pixel

Wide-viewing holographic stereogram based on self-interference incoherent digital holography.
Optics Express, 2022 We propose a holographic stereogram synthesis method which uses holograms that are optically captured by self-interference incoherent digital holography (SIDH) based on a geometric phase lens.

Holostereosynthesis: An Improvement to Louis Lumière’s Photostereosynthesis Technique
Applied Sciences, 2022 In 1920, Louis Lumière, one of the fathers of Cinématograph, invented photostereosynthesis, a photography technique that could recreate three-dimensional images without a specific artifice.

Implementation of the real-virtual 3D scene-fused full-parallax holographic stereogram.
Optics Express, 2021 This work focuses on the generation of three-dimensional (3D)-scene information as well as the fusion of real and virtual 3D scene information for the full-parallax holographic stereogram based on the effective perspective images' segmentation and ...

Digital Holographic Printing Methods for 3D Visualization of Cultural Heritage Artifacts
Digital Presentation and Preservation of Cultural and Scientific Heritage, 2014 Holography enables capture and reconstruction of the optical field scattered from three-dimensional (3D) objects. The hologram encodes both amplitude and phase of the field under coherent illumination, whereas photography records only the amplitude by ...

Studying the Recent Improvements in Holograms for Three‐Dimensional Display
International Journal of Optics, Volume 2014, Issue 1, 2014., 2014 Displayers tend to become three‐dimensional. The most advantage of holographic 3D displays is the possibility to observe 3D images without using glasses. The quality of created images by this method has surprised everyone. In this paper, the experimental steps of making a transmission hologram have been mentioned.
