A new invention
opens the door to a new generation of outdoor displays. Different pictures can
be seen at different angles, creating 3D effects without the need for 3D
glasses. Public screenings have become an important part of major sports
events. In the future, we will be able to enjoy them in 3D, thanks to a new
invention from Austrian scientists. A sophisticated laser system sends laser
beams into different directions. Therefore, different pictures are visible from
different angles. The angular resolution is so fine that the left eye is
presented a different picture than the right one, creating a 3D effect.
TriLite and TU
Vienna have created the first prototype. Currently it only has a modest
resolution of five pixels by three, but it clearly shows that the system works.
At the moment, they are creating a second prototype, which will display colour
pictures with a higher resolution. But the crucial point is that the individual
laser pixels work. Scaling it up to a display with many pixels is not a
problem. To experience the 3D effect, the viewer must be positioned in a
certain distance range from the screen. If the distance is too large, both eyes
receive the same image and only a normal 2D picture can be seen.
