Paper Abstract

The novel frequency-multiplexed modulator architecture of the MIT Mark III holo-video display poses a significant challenge in generation of appropriate video signals. Unlike in our previous work, here it is necessary to generate a group of adjacent single-sideband RF signals; as this display is intended to be manufacturable at consumer-electronics prices we face the added requirement of compact and inexpensive electronics that are compatible with standard PC graphics processors. In this paper we review the goals and architecture of Mark III and then describe our experiments and results in the use of a hardware/software implementation of Weaver's single-sideband modulation method to upconvert six 200MHz baseband analog video signals to a set of RF signals covering a nearly contiguous 1GHz range. We show that our method allows efficient generation of non-overlapping signals without aggressive filtering.
