Thanks to a new invention from Austrian scientists, in the future we will be able to enjoy public screenings in 3-D, which have become an important part of major sports events. A sophisticated laser system sends laser beams into different directions due to which different pictures are visible at different angles and the angular resolution is so fine that the left eye sees a different picture than the right one which creates a 3-D effect.
In 2013, a startup company TriLite Technologies had the idea to develop this new kind of display, which sends beams of light directly to the viewers' eyes. This project was carried out together with the Vienna University of Technology.
TriLite and TU Vienna together have created the first prototype, for now it only has a modest resolution of five pixels by three. Jörg Reitterer (TriLite Technologies and graduate student in the team of Prof. Ulrich Schmid at the Vienna Univ. of Technology) says that "We 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,".
Every single 3-D-Pixel also called as trixel consists of lasers and a moveable mirror. Ulrich Schmid says that "The mirror directs the laser beams across the field of vision, from left to right. During that movement the laser intensity is modulated so that different laser flashes are sent into different directions,". The viewer must be positioned at a certain distance range from the screen so as to experience the 3-D effect. If the person isn't in the range then both the eyes will receive the same image and a normal 2-D picture would be seen. The range to experience 3-D effect can be tuned according to the local requirements.
Unlike the 3-D movies in the cinemas that only shows two different pictures—one for each eye, This newly developed display, is capable of presenting hundreds of pictures. One can get a view of the displayed object from different sides, while walking by the display just like while passing a real object.For this, a new video format is required, which has already been developed by the researchers. Franz Fiedler, CTO of TriLite Technologies says that "Today's 3-D cinema movies can be converted into our 3-D format, but we expect that new footage will be created especially for our displays—perhaps with a much larger number of cameras,".
Since the display is very vivid, it can be used outdoors, even in bright sunlight.Electronic billboards could display different ads, seen from different angles. Ferdinand Saint-Julien, CEO of TriLite Technologies says that "Maybe someone wants to appeal specifically to the customers leaving the shop across the street, and a different ad is shown to the people waiting at the bus stop,". This would not be a problem technologically.
It took only three years to get from the first designs to a working prototype."We are very happy that the project was so successful in such a short period of time," says Schmid. This technology has now been patented and presented in several scientific publications, and the second prototype would probably be finished by the middle of the year and the commercial launch is scheduled for 2016.
