A New Approach to Computer-Generated Holography

Applied Optics, 1970
A digital computer and automatic plotter have been used to produce a series of perspective views of a computer-stored three-dimensional object which is slightly rotated for each view. All of these views are combined together optically to produce a final hologram which can be viewed in high ambient light conditions. The reconstructed image appears three

Optical wavelet transforms from computer-generated holography

Applied Optics, 1994
An optical implementation of a wavelet transform is presented. Optical Haar wavelets are created by the use of computer-generated holography. Two different holographic techniques are explored: (1) interferogram and (2) detour-phase. A discrete representation of a continuous wavelet transform is obtained by the optical correlation of an image with a ...

Computer generated holography for computer graphics

2011 3DTV Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON), 2011
3D 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 ...

Iterative Approaches To Computer Generated Holography

SPIE Proceedings, 1988
The iterative alternating projections onto constraint sets (POCS) algorithm is applied to the design of computer-generated holograms (CGH's). The performance of the resulting CGH's is compared to those designed by the non-iterative error diffusion algorithm and direct binary search (DBS), which is another iterative technique. Both iterative methods are

New approach to computer-generated holography

SPIE Proceedings, 1990
A 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.

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.

New approaches to computer-generated holography

Annual Meeting Optical Society of America, 1989
Computer-generated holograms have limitations such as in quality of coding, space-bandwidth product, and plotting technologies. In representation of 3-D information, the problem of how to represent 3-D scenes so that they can be viewed with satisfaction presents an important challenge.

New method for computer-generated holography

Optical Society of America Annual Meeting, 1990
A 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.

Computer simulated holography and computer generated holograms

American Journal of Physics, 1996
The 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.
