Double-multiplexed computer-generated holograms

OSA Annual Meeting, 1993
The most important element in an optical data processor is the complex spatial filter. Lohmann and Paris1 invented the detour phase method for binary encoding of a complex filter function. The reconstructed object is obtained along the first diffraction order.

Polarizing computer-generated holograms

Optical Engineering, 1993
Polarizing 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.

New computer-generated hologram

SPIE Proceedings, 1997
A 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.

Stereoscopic Computer-Generated Hologram

Digital Holography and Three-Dimensional Imaging, 2016
Stereoscopic 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.

Applications of Computer Generated Hologram

Advances in Imaging, 2009
In this paper we describe the use of computer-generated holograms in creating light diffusing film for use in back lighted liquid crystal displays (LCD).
