A single‐panel complex holographic display with a three‐phase covalent macropixel featuring ultralow noise and high‐efficiency 3D image generation is proposed. The essential feature of the proposed three‐phase covalent macropixel is the point‐symmetric covalent concatenation of sub‐pixels and an adaptive computer‐generated hologram encoding algorithm. The proposed single‐panel holographic display exhibits three times signal efficiency enhancement, 1/38 reduction of DC noise, and 1/50 reduction of conjugate noise compared to conventional holographic displays in the generation of full‐color computer‐generated hologram images. This noise reduction leads to three times the optical efficiency enhancement of holographic displays. [ABSTRACT FROM AUTHOR]

While recent research has shown that holographic displays can represent photorealistic 3D holograms in real time, the difficulty in acquiring high-quality real-world holograms has limited the realization of holographic streaming systems. Incoherent holographic cameras, which record holograms under daylight conditions, are suitable candidates for real-world acquisition, as they prevent the safety issues associated with the use of lasers; however, these cameras are hindered by severe noise due to the optical imperfections of such systems. In this work, we develop a deep learning-based incoherent holographic camera system that can deliver visually enhanced holograms in real time. A neural network filters the noise in the captured holograms, maintaining a complex-valued hologram format throughout the whole process. Enabled by the computational efficiency of the proposed filtering strategy, we demonstrate a holographic streaming system integrating a holographic camera and holographic display, with the aim of developing the ultimate holographic ecosystem of the future. The authors develop a deep learning-based incoherent holographic camera system in order to deliver visually enhanced holograms in real-time. The neural network filters the noise in the captured holograms, and by integrating a holographic camera and a display, they demonstrate a holographic streaming system. [ABSTRACT FROM AUTHOR]

A new architecture for a flat panel three‐dimensional holographic display is proposed. We developed a beam steering backlight, which is achieved by the integration of a beam deflector and a coherent backlight unit. In addition, a hologram processor is implemented as a single‐chip FPGA. We built a flat prototype that is slim as 10cm thick. It shows high‐resolution holographic images with an improved viewing angle. [ABSTRACT FROM AUTHOR]

Novel 3D display architecture and algorithm are proposed and demonstrated Full HD 3D image with reduced accommodationvergence conflict using limited computing power and a conventional LCD panel. The proposed 3D display architecture is integrated with a commercial 5.5" Full HD LCD panel and the used algorithm needs remarkably lower computing power than a conventional CGH algorithm based on Fresnel transformation. The experimental results show the accommodation depth cue which provides a clear 3D image only on focus position. [ABSTRACT FROM AUTHOR]

Holographic display is considered as the ultimate 3D technology. However, technical challenges in device capability and computation inhibit its commercialization. This talk addresses several approaches to overcome these challenges. [ABSTRACT FROM AUTHOR]

Since its discovery almost 70 years ago, the hologram has been considered to reproduce the most realistic three dimensional images without visual side effects. Holographic video has been extensively researched for commercialization, since Benton et al. at MIT Media Lab developed the first holographic video systems in 1990. However, commercially available holographic video displays have not been introduced yet for several reasons: narrow viewing angle, bulky optics and heavy computing power. Here we present an interactive slim-panel holographic video display using a steering-backlight unit and a holographic video processor to solve the above issues. The steering-backlight unit enables to expand the viewing angle by 30 times and its diffractive waveguide architecture makes a slim display form-factor. The holographic video processor computes high quality holograms in real-time on a single-chip. We suggest that the slim-panel holographic display can provide realistic three-dimensional video in office and household environments. Holographic displays that are both compact and produce realistic holograms without eyestrain are still difficult to realize. Here the authors implement a steering-backlight unit and a holographic video processor to produce a realistic holographic display in a slim panel. [ABSTRACT FROM AUTHOR]
