Three-Dimensional Fourier-Transform Method for Synthesizing Binary Holograms*
Journal of the Optical Society of America, 1968A new method for the synthesis of holograms, based on a Fourier transformation, has been theoretically derived and experimentally verified. The method extends the familiar two-dimensional optical Fourier-transform analysis to include objects located in a volume centered about the focal point of the transform lens, and is specifically developed to ...

Analysis of the leakage from computer-generated holograms synthesized by direct binary search
Journal of the Optical Society of America A, 1989Images reconstructed from computer-generated holograms synthesized by the iterative direct binary search (DBS) technique suffer from noise due to leakage from uncontrolled parts of the diffraction pattern. The statistics of the nonhomogeneous leakage noise are analyzed under the assumption of independent, identically distributed (iid) addressable ...

Improvement of camera arrangement in computer-generated holograms synthesized from multi-view images
SPIE Proceedings, 2011Computer-generated hologram (CGH) is a technique that enables recording optical systems for holography by computer simulation, and can reconstruct ideal 3D images. Since CGH requires the model data of objects, it is necessary for creating 3D images of real existing objects to model them precisely.

Holo-graphics: A Framework for Synthesizing Hologram of Complex Object Scene
3D Research, 2014This paper reports a novel concept known as “Holo-graphics”, a term that is an amalgamation of “hologram” and “computer graphics”. The idea is to explore a method whereby traditional computer graphic techniques can be applied in synthesizing holograms of complicated object scenes.

Chinese Optics Letters, 2014
A novel method to extract a bounding box that contains the three-dimensional object from its spherical hologram is proposed. The proposed method uses the windowed Fourier transform to obtain the angular distribution of the quasi-collimated beams at each position in the spherical hologram and estimates ...

How the method of representing an object affects the imaging properties of synthesized holograms
Journal of Optical Technology, 2015This paper establishes how the method of representing an object affects the imaging properties of synthesized holograms. It is shown that, if a hologram is synthesized by representing an object on the basis of its spatial-frequency analysis, this disrupts the structure of the reconstructed image—i.e., it causes the reconstructed image to be displayed ...

2004 23rd IEEE Convention of Electrical and Electronics Engineers in Israel, 2004
A new method of synthesizing computer-generated holograms of three-dimensional (3D) objects is proposed. Several projections of the 3D object are numerically processed to yield a two dimensional complex function, which is then encoded as a computer-generated hologram.

Scattering of Light by Spherical Liquid Droplets Using Computer-Synthesized Holograms
Journal of the Optical Society of America, 1968A cathode-ray tube linked to a computer is used to synthesize holograms of spherical liquid droplets illuminated by plane waves of monochromatic linearly polarized light. The classical Mie solution is employed to determine the far-field radiation pattern of the light waves scattered by the droplets.

Fitoterapia
A series of novel amide-fused isosteviol derivatives were designed and synthesized. Their cytotoxicities in vitro against HCT-116 cells were screened. The preliminary bioassays indicated that most of the title compounds exhibited noteworthy cytotoxicity.
