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

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.

Computer generation of binary Fresnel holography
Applied Optics, 2011Binarization of Fresnel holograms by direct thresholding based on the polarity of the fringe pattern is studied. It is found that if the hologram is binarized (i.e., for black and white hologram pixels) in this manner, only the edges of the object are preserved in the reconstructed image. To alleviate the errors caused by binarization, the use of error

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

Full phase and amplitude control in computer-generated holography
Optics Letters, 2009We report what we believe to be the first realization of a computer-generated complex-valued hologram recorded in a single film of photoactive polymer. Complex-valued holograms give rise to a diffracted optical field with control over its amplitude and phase.
