Hardware Implementations of Computer-Generated Holography: A Review [PDF]
Optical Engineering, 2020 Computer-generated holography (CGH) is a technique to generate holographic interference patterns. One of the major issues related to computer hologram generation is the massive computational power required.

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

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

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.

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.

Iterative Approaches To Computer-Generated Holography*
Signal Recovery and Synthesis III, 1989Optics is playing an increasingly important role in the sensing, processing, and transmission of information. The elements that shape the wavefront at various points are a key part of any optical system. In many cases, computer-generated holograms (CGH’s) offer major advantages over conventional refractive optical elements in terms of size, weight, and
