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 with ordinary display
Optics Letters, 2023We propose a method of computer-generated holography (CGH) using incoherent light emitted from a mobile phone screen. In this method, we suppose a cascade of holograms in which the first hologram is a color image displayed on the mobile phone screen. The hologram cascade is synthesized by solving an inverse problem with respect to the propagation of ...

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.

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).

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
