Researchers claim to have cracked the problem of creating giant displays that can show images in 3D without the need for glasses.
Austrian researchers have developed a laser system that sends different images to each eye – and say it could lead to New York’s Times Square having its first 3D ads.
It could also mean the end of having to don cumbersome glasses at the cinema, they say, and be used to show sporting events on huge screens in 3D – allowing hundreds of people to see the image at the same time.
The 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.
