Paper Abstract

"Holo-Chidi" is a holographic video processing system designed at the Massachusetts Institute of Technology (MIT) Media Laboratory for real-time computation of computer-generated holograms and the subsequent display of the holograms at video frame rates. The Holo-Chidi system is composed of two sets of cards—the set of processor cards and the set of video concentrator cards (VCCs). The processor cards are used for hologram computation, data archival/retrieval from a host system, and for higher level control of the VCCs. The VCC formats computed holographic data from multiple hologram-computing processor cards, converting the digital data to analog form to feed the acousto-optic modulators of the Media Lab's "MarkII" holographic display system. Both the processor card and VCC are fabricated and tested, integrating both sets of cards with a host system is currently in progress. The design and implementation of the Holo-Chidi system is discussed.
