Observation of self-accelerating Bessel-like optical beams along arbitrary trajectories [PDF]

, 2013
We experimentally demonstrate self-accelerating Bessel-like optical beams propagating along arbitrary trajectories in free space. With computer generated holography, such beams are designed to follow different controllable trajectories while their main ...

Non-hogel-based computer generated hologram from light field using complex field recovery technique from Wigner distribution function.

Optics Express, 2019
We propose a novel method that synthesizes computer-generated holograms from light field data. Light field, or ray space, is the spatio-angular distribution of light rays coming from three-dimensional scene, and it can also be represented using a large ...

Application of Kinoform CGHs to an ID Tag System

IEEE Photonics Journal, 2010
In this paper, we successfully apply multilevel kinoform computer-generated hologram (CGH) patterns, which are recorded on a fine texture paper by a photo printer, into the hologram identification (ID) tag system.

Curved multiplexing computer-generated hologram for 3D holographic display.

Optics Express, 2019
A curved multiplexing method based on the curved computer-generated hologram (CCGH) is proposed theoretically and demonstrated experimentally to increase field of view (FOV) and spatial bandwidth. Point source method is used to calculate the CCGH. Curved

Foveated computer-generated hologram and its progressive update using triangular mesh scene model for near-eye displays.

Optics Express, 2019
We propose a computer-generated hologram technique that reduces latency caused by hologram calculations in holographic near-to-eye displays. The proposed method applies a foveated rendering technique to a triangular mesh-based computer-generated hologram

Quantum Computer-Generated Holography

IEEE Access
Hologram calculations pose a significant challenge for future holographic displays with extensive fields of view and wide viewing angles. Classical computers may encounter difficulties with these owing to immense computational demands.
