Computer-generated holography in the intermediate domain

open access: yesJournal of the Optical Society of America A, 2022
Iterative Fourier transform algorithms are widely used for hologram generation for phase-modulating spatial light modulators. In this paper, we introduce a new technique called the “intermediate domain,” which decomposes the Fourier transforms used into multiple subtransforms, the combination of which can offer major performance

Interactive Holographic Display for Real-Time Drawing and Erasing of 3D Point-Cloud Images With a Fingertip

open access: yesIEEE Access, 2021
We demonstrate an interactive holographic display system for real-time drawing and erasing of 3D point-cloud images. This system detects the position of the observer's fingertip with a motion sensor, which it uses to calculate the complex amplitude ...

Computer Generated Holography [PDF]

open access: yesJournal 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.

Photorealistic Rapid Computer-Generated Holography Employing an Enhanced Path Tracing Technique With Sequence Generated Trial

open access: yesIEEE Photonics Journal, 2023
Fast holographic generation technology depends on the swift creation of computer-generated holograms (CGHs). Currently, the fast generation method of computer-generated holograms based on ray tracing is still based on non-physical ray tracing methods ...
