Bandwidth Control in Computer- Generated Holography
IEEE Photonics Journal, 2023 The Fourier transform between the time and frequency signals of light enables highly efficient band usage in optical communications. Analogously, the Fourier transform between the wavefield and wavevector distributions in the optical spatial diffraction ...

Computer-generated holography with ordinary display
Optics Letters, 2023 We propose a method of computer-generated holography (CGH) using incoherent light emitted from a mobile phone screen. In this method, we suppose a cascade of holograms in which the first hologram is a color image displayed on the mobile phone screen. The hologram cascade is synthesized by solving an inverse problem with respect to the propagation of ...

Perceptually Guided Computer-generated Holography [PDF]
London Imaging Meeting, 2022 Computer-Generated Holography (CGH) promises to deliver genuine, high-quality visuals at any depth. We argue that combining CGH and perceptually guided graphics can soon lead to practical holographic display systems that deliver perceptually realistic ...

Simultaneous Color Computer Generated Holography
SIGGRAPH Asia 2023 Conference Papers, 2023 Computer generated holography has long been touted as the future of augmented and virtual reality (AR/VR) displays, but has yet to be realized in practice. Previous high-quality, color holographic displays have made either a 3$\times$ sacrifice on frame rate by using a sequential color illumination scheme or used more than one spatial light modulator ...

Holographic Tailoring of Structured Light Field with Digital Device
Photonics, 2022 Structured light fields have attracted much attention due to rich spatial degrees of freedom. The tailoring of an arbitrary structured light field on demand is the precondition for the application of structured light.

Computer-generated holography in the intermediate domain
Journal 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

Synthesizing optical spectra using computer-generated holography techniques
New Journal of Physics, 2021 Experimental control and detection of atoms and molecules often rely on optical transitions between different electronic states. In many cases, substructure such as hyperfine or spin-rotation structure leads to the need for multiple optical frequencies ...

Computer-Generated Hologram Based on Reference Light Multiplexing for Holographic Display
Applied Sciences, 2021 In this article, we propose a reference light wave multiplexing scheme to increase the information capacity of computer-generated holograms. The holograms were generated by different reference light waves and superimposed together as a multiplexed ...

Reconstructing the history of holography [PDF]
, 2003 This paper discusses large-scale but gradual changes in the subject of holography that have only recently become readily observable. Presenting an analysis of publications in holography over the past half century, the paper illustrates and discusses the ...
