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 generated holography: novel procedure
Optics Communications, 1993Abstract It is shown that the spatially filtered image of a generalized wide slit can be used for synthesizing 1D complex amplitude distribution, in a similar fashion to computer generated holography.

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.

Iterative Approaches To Computer Generated Holography
SPIE Proceedings, 1988The 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

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 ...

A Pre-History of Computer-Generated Holography
Optics and Photonics News, 2008This month’s edition of the journal Applied Optics is a special issue devoted to the contributions of Emmett Leith, who passed away unexpectedly in December 2005. To honor the memory of my dear friend and colleague, I provide here my account of the significance of his work and how I came to invent computer-generated holography.

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.
