Abstract

Electronic interactive three-dimensional holography may someday be the most efficient tool for expressing and communicating visual information. However, its development has been limited by the need for rapid digital synthesis of holographic fringe patterns. Holographic fringe computation is difficult due to the huge size of a fringe pattern (typically over 100 mega-samples!) and the complexity of the calculation for each sample.

A "diffraction-specific" fringe computation method enables computation at interactive rates by reducing complexity and computational bandwidth. Using spatial and spectral sampling, this method allows bandwidth compression by more than twenty to one and speed-up by more than one hundred to one. It can be efficiently implemented on a variety of computing platforms. The development of larger, faster, more practical electro-holographic systems allows for numerous applications and the investigation of new paradigms of human-computer interaction.

The talk will describe this new computation method as well as the electro-optics of holovideo displays developed at the MIT Media Lab. It will describe current research in this new field, and discuss potential applications in scientific visualization, medical imaging, education and entertainment.
