Incoherent computer-generated holography
Optics Letters, 2022We present a method for computer-generated holography (CGH) using spatially and temporally incoherent light. The proposed method synthesizes a hologram cascade by solving an inverse problem for the propagation of incoherent light. The spatial incoherence removes speckle noise in CGH, and the temporal incoherence simplifies the optical setup, including ...

Graphic Codes for Computer Holography
Applied Optics, 1995Several aspects of graphic codes of computer-generated holograms are discussed. This is in contrast to the algorithmic studies that have dominated research in the field of computer holography in recent years. We study the graphic cells of binary cell-oriented holograms under the aspects of specificfabrication and performance problems such as the pen ...

Computer graphics for holography
IEEE Computer Graphics and Applications, 1992Holograms composed from a multiplicity of independent object views, referred to as composite holograms, are discussed. Three techniques, one an extension of old techniques and the others new, are presented. The latter are called the direct method and the postrendering method. The direct approach is favored because it uses less disk space.

Double-sided computer-generated holography
Optics Letters, 2023We present a method for computer-generated holography (CGH) in which different images are reproduced on both sides of a hologram with a single illumination source. In the proposed method, we use a transmissive spatial light modulator (SLM) and a half mirror (HM) located downstream of the SLM. The light modulated by the SLM is partially reflected by the

Digital holography optically generates a hologram, which is then recorded on a CCD camera, and an image is reconstructed using digital techniques. This chapter discusses the converse, i.e., the hologram is digitally generated and the reconstruction is performed optically, a process known as computer-generated holography (CGH).

Computer holography as an application of computational optics
SPIE Proceedings, 2015Several techniques are reviewed in high-definition computer holography. These techniques are based on numerical techniques in wave optics. For example, the polygon-based method based on propagation between tilted planes is used for calculating the field of polygonal surface sources of light.

A New Approach to Computer-Generated Holography
Applied Optics, 1970A digital computer and automatic plotter have been used to produce a series of perspective views of a computer-stored three-dimensional object which is slightly rotated for each view. All of these views are combined together optically to produce a final hologram which can be viewed in high ambient light conditions. The reconstructed image appears three

Computer-generated holography in photorefractive materials
Optics Letters, 1990We describe a method to create and reconstruct computer-generated Fourier-transform holograms in photorefractive materials. Holographic reconstructions are obtained from computer-generated data by imaging computer-generated holograms into a BaTiO3 crystal, using either spatially coherent or incoherent light.
