Digital holography optically generates a hologram, which is then recorded on a CCD camera, and an image is reconstructed using digital techniques. This chapter discusses the converse, i.e., the hologram is digitally generated and the reconstruction is performed optically, a process known as computer-generated holography (CGH).

Iterative Approaches To Computer-Generated Holography*
Signal Recovery and Synthesis III, 1989Optics is playing an increasingly important role in the sensing, processing, and transmission of information. The elements that shape the wavefront at various points are a key part of any optical system. In many cases, computer-generated holograms (CGH’s) offer major advantages over conventional refractive optical elements in terms of size, weight, and

Computer generated holography for computer graphics
2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON), 20113D displays are now rapidly designed, enhanced and sold. It is expected that after a boom of displays based on active glasses, new display generations will appear. Those would be probably displays with passive glasses, multiview autostereoscopic displays based on parallax barrier or lenticular technology, and displays based on integral photography ...

Full phase and amplitude control in computer-generated holography
Optics Letters, 2009We report what we believe to be the first realization of a computer-generated complex-valued hologram recorded in a single film of photoactive polymer. Complex-valued holograms give rise to a diffracted optical field with control over its amplitude and phase.

New approach to computer-generated holography
SPIE Proceedings, 1990A new fast approach to computer-generated holography for 3-D objects points in arbitrary positions in 3-D space is presented. The approach is based on fast computation of weighted zero-crossings their accumulation and thresholding to achieve a coded hologram to be physically generated. 1.

Computer simulated holography and computer generated holograms
American Journal of Physics, 1996The success of calculating and displaying the Fraunhofer diffraction patterns for various apertures using the fast Fourier transform algorithm on an IBM compatible personal computer has been well documented in the recent literature. In this paper the technique is extended to the simulation of optical holography on the computer.

New method for computer-generated holography
Optical Society of America Annual Meeting, 1990A new method for computer-generated holography is introduced, based on stacking zero crossings of partial wavefields and then quantizing. A fast method for finding the zero crossings when each partial wavefield results from a point source in space is discussed.

NeRF-based computer-generated holography
Optica Digital Holography and Three-Dimensional Imaging 2024 (DH)This study introduces hologram generation from two-dimensional images using neural radiance fields (NeRF). The proposed method enables the generation of holograms capable of reproducing 3D images viewing at arbitrary viewpoints.
