Computer-generated Binary Holograms
IBM Journal of Research and Development, 1969Holograms synthesized by computer are used for constructing optical wavefronts from numerically specified objects. Elimination of the need for a physical object has made new applications possible, for example, three-dimensional computer output displays, synthetic prototypes for interferometric testing, and filters for various optical data processing ...

New computer-generated hologram
SPIE Proceedings, 1997A method for calculating in real time, the transmission function of a computer generated hologram (CGH) for beam shaping, is described. This method is based on the well known phase contrast method (PCM) in which phase distributions of an object are transformed to intensity distributions.

Computer-generated microwave holograms
American Journal of Physics, 1980Using the phasor method of superposition of waves, the intensity pattern from a system of microwave sources is calculated point by point on a plane corresponding to a film emulsion. The pattern is printed and directly converted to a hologram for 3-cm microwaves.

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.

Multichannel computer generated holograms
2000 Digest of the LEOS Summer Topical Meetings. Electronic-Enhanced Optics. Optical Sensing in Semiconductor Manufacturing. Electro-Optics in Space. Broadband Optical Networks (Cat. No.00TH8497), 2002Detour phase computer generated holograms still remain under research due to their interesting characteristics. Many researchers have proposed several multiplexing methods, using detour holograms, where they have been able to perform an image reconstruction in various diffraction orders.

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.

Polarizing computer-generated holograms
Optical Engineering, 1993Polarizing computer-generated holograms (PCGH) may be useful combining different optical functions such as polarizing, imaging, beam shaping, and beamsplitting in one element. We propose the fabrication of PCGHs based on microstructuring of polarizing or birefringent materials.
