Stereoscopic Computer-Generated Hologram
Digital Holography and Three-Dimensional Imaging, 2016Stereoscopic computer-generated hologram (SCGH) is able to provide accurate depth cues for three-dimensional display. We proposed to use look-up table instead of directly point-by-point computation to reduce the computation time of SCGH. The problem of artifacts arose in using lookup table is also discussed.

Transport-of-intensity holographic data storage based on a computer-generated hologram.
Applied Optics, 2018To increase the recording density of computer-generated-hologram (CGH)-based holographic data storage, a phase data page reconstruction method by the transport of intensity equation (TIE) is proposed.

Computer-Generated Disk Hologram
Biomedical Optics, 2008It is difficult to realize a computer-generated disk hologram due to the needs of high resolution output and huge computation. We have achieved to make the computer-generated disk hologram by using the fringe printer.

Reconfigurable computer generated holograms
Optics Communications, 1994Abstract Reconfigurable Fourier plane computer generated holograms are implemented by optically reducing a binary hologram image from an electrically addressed spatial light modulator onto a phase-only optically addressed spatial light modulator.

Cylindrical computer-generated hologram for displaying 3D images.
Optics Express, 2018A method for computing and synthesizing a diffractive optical element (DOE) on a cylindrical surface is proposed. The computer-generated hologram is a phase reflecting DOE, which, when illuminated with white light, displays a 3D image with a 360° viewing

Phase-regularized polygon computer-generated holograms
Optics Letters, 2014The dark-line defect problem in the conventional polygon computer-generated hologram (CGH) is addressed. To resolve this problem, we clarify the physical origin of the defect and address the concept of phase-regularization. A novel synthesis algorithm for a phase-regularized polygon CGH for generating photorealistic defect-free holographic images is ...

Mapping distortion correction in freeform mirror testing by computer-generated hologram.
Applied Optics, 2018Distortion can be introduced in null testing using computer-generated holograms for off-axis aspheres or freeforms with significant deviation. It leads to the failure of testing results to guide deterministic optical processing.

Computer-generated holograms for geometric transformations
Applied Optics, 1984Theory and experiments in the area of computer-generated holograms for geometric transformations are presented. Geometric transform holograms are divided into two categories: (1) those which have a continuous fringe structure, and (2) those which consist of a set of discrete subholograms.

Basic stages in the synthesis of computer generated holograms are: (i) formulating mathematical models of the object and of the usage of the hologram; (ii) computing the mathematical hologram, or distribution of the wave front amplitude and phase in the hologram plane; (iii) encoding samples of the mathematical hologram for recording them on the ...

Computer-generated holograms (CGH’s) are diffractive-optical elements that offer the possibility of creating wave-optical display systems that are under complete computer control. Because CGH’s can control all aspects of the optical wave, three-dimensional imagery can be presented to an audience. After reviewing some mathematical preliminaries that are
