3D movies are amazing but there are times when you'll walk away with a killer headache. A group of researchers at IMEC believes that holographic video might be the best way around this problem and has been working on a means of constructing holographic displays by shining lasers on microelectromechanical systems (MEMS) platforms capable of moving up and down like small, reflective pistons. Here's the cool part: each pixel would have a spring-like mechanism attached to it that could be moved by applying voltage to it. In the first stage of the technology, a laser is bounced off a MEMS-less chip containing an image, the diffracted light interfering to create a 3D picture. From here, the team can adjust the image by replacing pixels with small, mirrored platforms that can alternate their direction to create a moving projection. It gets technical after this, but you can take a gander at the video after the break for a full demo and explanation.
