Paper Abstract

Electronic holographic imaging, as developed at the MIT Media Laboratory's Spatial Imaging Group, is a truly 3D real-time digital imaging medium. Recent progress in holographic video has demonstrated that the crucial technologies--computation, electronic signal manipulation, and optical modulation and scanning--may be scaled up to produce larger, more interactive, full-color holographic images. The overcoming of communication bottlenecks relies on the use of newly-developed 'diffraction-specific' computational algorithms to produce encoded holograms that are compressed by factors of about twenty to one. Here we describe progress in the very rapid 'decompression' of the holograms with stream-processor hardware built for the Cheops video processing system. The result is that 36-MB holographic images may be updated over a SCSI link in about six seconds, approaching truly interactive speed.
