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.
