MOVING hologram displays like those featured in Star Wars could soon be available to watch on a laptop.
Scientists have cracked a major technological hurdle to make low-cost, high quality holographic videos a reality.
Until now, the video hologram has generally been confined to science fiction, the most famous example being the projected image of Princess Leia in the first Star Wars film.
Existing systems that project moving holographic images are costly and suffer from severe limitations.
The chief problem lies with devices called spatial light modulators, which direct light to form points in three dimensional space.
With current technology, key elements of display size, viewing angle, frame rate and depth of image are restricted.
But now US engineers at the Massachusetts Institute of Technology have developed a new kind of spatial light modulator that overcomes most of these problems......
