Giant billboards in 3-D, no glasses needed
Engineers in Austria have created a giant laser system that sends beams in different directions, which makes them visible from many 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.
In 2013, the start-up company TriLite Technologies had the idea to develop this new kind of display, which sends beams of light directly to the viewers’ eyes.
To experience the 3-D 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. The range in which the 3D effect can be experienced can be tuned according to the local requirements.
The newly developed display, can present hundreds of pictures. Walking by the display, one can get a view of the displayed object from different sides, just like passing a real object. For this, however, a new videoformat is required, which has already been developed by the researchers.
The technology has now been patented and presented in several scientific publications. The second prototype should be finished by the middle of the year, the commercial launch is scheduled for 2016.
