Computer Generated Holography [PDF]

Journal of Optics, 1978
The article reviews the state of art of the computer generated holography. Sec. 2 deals with the various coding schemes to record both the amplitude and phase of the field at the hologram plane. Special emphasis is given to those coding schemes which are used for the generation of binary holograms.

Gaussian Wave Splatting for Computer-Generated Holography [PDF]

ACM Transactions on Graphics
State-of-the-art neural rendering methods optimize Gaussian scene representations from a few photographs for novel-view synthesis. Building on these representations, we develop an efficient algorithm, dubbed Gaussian Wave Splatting, to turn these Gaussians into holograms.

Multifocal co-plane metalens based on computer-generated holography for multiple visible wavelengths

Results in Physics, 2020
Traditional optical components need to accumulate optical path to control the wavefront. To achieve a desired function, several components are cascaded resulting in optical systems that are bulky and costly.
