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 ...

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

Computer-Generated Holography as a Generic Display Technology
Computer, 2005Computer-generated holography technique is a powerful technology suitable for a wide range of display types, including 2D, stereoscopic, autostereoscopic, volumetric, and true 3D imaging. Computer-generated holography is an emerging technology, made possible by increasingly powerful computers, that avoids the interferometric recording step in ...

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.

Complementary Computer Generated Holography for Aesthetic Watermarking
Optics Express, 2012 We present herein an original solution for the watermarking of holograms in binary graphic arts without unaesthetic diffractive effect. It is based on the Babinet principle of complementary diffractive structures adapted to Lohmann-type computer generated holograms.

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).
