Holographic Near-Eye 3D Display Method Based on Large-Size Hologram
Frontiers in Materials, 2021 In this paper, we propose a holographic near-eye 3D display method based on large-size computer-generated hologram (CGH). The reconstructed image with a large viewing angle is obtained by using a time multiplexing and spatial tiling system.

Angling for A Better View [PDF]
Biophysical Journal, 2016 Viewing long-standing questions and challenges through a different lens can often provide unique insights and perspectives. This has been the key to many of the innovations emerging in the field of optical microscopy. Whether one is devising novel superresolution localization microscopies (1), new imaging reagents (2,3), or exploiting new imaging ...

Expansion of Image Space in Enhanced-NA Fresnel Holographic Display
Applied Sciences, 2022 The enhanced-NA Fresnel hologram reconstructs a holographic image at a viewing angle larger than the diffraction angle of a hologram pixel. The image space is limited by the bandwidth of a digital hologram.

Wide-viewing integral imaging system using polarizers and light barriers array
Journal of the European Optical Society-Rapid Publications, 2017 Background Integral imaging is considered one of the most promising three-dimensional display technologies, while the limited viewing angle is regarded as a primary disadvantage of integral imaging display to reach a commercial level. This paper proposes

Viewing Short Gamma-Ray Bursts From a Different Angle
Frontiers in Astronomy and Space Sciences, 2020 The detection of a faint, short gamma-ray burst (GRB 170817A) in coincidence with the gravitational wave (GW 170817) detection by LIGO/Virgo is at odds with the expected known luminosity and redshift distribution of short GRBs (sGRB).
