Like Star Wars - holograms on laptops to become reality?
- 20 June 2013
Holograms are usually only something that you'd see in science fiction movies, but Scientists say they have solved a big technological problem which could make holographic videos part of every day life.
Unlike a 3D image, a holographic projection allows you to move around and get different views from all angles.
Until now, systems that make moving holographic images have cost a lot of money and have been very limited.
The main problem was with devices called 'spatial light modulators', which direct light to form points in three dimensional space, creating holograms.
But now engineers at the Massachusetts Institute of Technology have developed a new special kind of spatial light modulator that solves the issue.
Scientists think that a holographic laptop screen, using the technology, could even be built for less than £320.
