Horizontal-parallax-only electronic holography.

Investigations of Horizontal - Parallax - Only Optical Scanning Holography ( HPO - OSH ) through MATLAB Simulations

Electronic display system for computational holography

We present an electro-optical apparatus capable of displaying a computer generated hologram (CGH) in real time. The CGH is calculated by a supercomputer, read from a fast frame buffer, and transmitted to a high-bandwidth acousto-optic modulator (AOM). Coherent light is modulated by the AOM and optically processed to produce a three-dimensional image with horizontal parallax.

Three-dimensional display of a horizontal-parallax-only hologram.

We propose a three-dimensional (3D) holographic display by converting an optically recorded complex full-parallax (FP) hologram to an off-axis horizontal-parallax-only (HPO) hologram. First, we record the complex FP hologram of an object using optical scanning holography. We then convert the complex FP hologram to an off-axis HPO hologram through fringe-matched Gaussian low-pass filtering and w...

ERRATUM: Image Size Scalable Full-parallax Coloured Three-dimensional Video by Electronic Holography

In electronic holography, various methods have been considered for using multiple spatial light modulators (SLM) to increase the image size. In a previous work, we used a monochrome light source for a method that located an optical system containing lens arrays and other components in front of multiple SLMs. This paper proposes a colourization technique for that system based on time division mu...

Interactive computation of holograms using a look-up table

Several methods of increasing the speed and simplicity of the computation of o axis transmission holograms are presented with applications to the real time display of holographic images The bipolar intensity approach allows for the real valued linear summation of interference fringes a factor of speed increase and the elimination of image noise caused by object self interference An order of mag...
