3-D Holographic images
The MIT Spatial Imaging Group began creating electro-holography which was
capable of producing realistic 3-D holographic images in real time in 1989.
Research produced interactive rates, full-color images, synthetic images and a
scale-up to a 36-MB display system. Currently, the capability can produce images
about 100 mm in width, height, and depth, through tranforming a 3-D numerical
description of the object scene into a holographic fringe pattern. The MIT
Holocube picture is a digitized photograph of a 3-D holographic image displayed.
The computed fringe pattern contained 2-MB per primary color, for a total of 6
MB. Image width is approximately 40 mm. It was computed on a massively parallel
supercomputer. Diffraction-Specific fringe computation based on the spatial and
spectral discretization of the hologram has yielded two types of holographic
bandwidth compression.
