Austrian scientists have invented a sophisticated laser system that creates a 3D effect without the need for special glasses. The display uses laser beams to send out different pictures into different directions.
As each pixel contains lasers and a moving mirror, which directs the laser light, different pictures are visible from different angles.
Different pictures can be sent to the right and the left eye of each viewer, so that 3-D effects become possible without the need for special glasses.
The angular resolution is so fine that the left eye is presented a different picture than the right one, creating a 3D effect, said researchers from Vienna University of Technology.
The display is vivid when compared to a movie screen. Therefore, it can be used outdoors even in bright sunlight.
With the start-up firm TriLite Technologies, researchers have created the first prototype that has a modest resolution of five pixels by three but it clearly shows that the system works.
“We are developing a second prototype which will display colour pictures with a higher resolution,” explained Jorg Reitterer from the team of professor Ulrich Schmid at Vienna University of Technology.
While 3D movies in the cinema only show two different pictures, one for each eye, 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 video format is required which has already been developed by the researchers.
“We are very happy that the project was so successful in such a short period of time,” says Ulrich Schmid. It took only three years to get from the first designs to a working prototype.
The technology has now been patented and presented in several scientific publications. While the second prototype is expected to be completed by the mid of 2015, the commercial launch is scheduled for 2016.
“Today’s 3D cinema movies can be converted into our 3D format, but we expect that new footage will be created especially for our displays – perhaps with a much larger number of cameras,” added Franz Fiedler of TriLite Technologies.
