Let's face it, 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.

This actually sounds promising. Real holographic TVs will probably be way more popular than current 3D tech. Its just a matter of time.

Yep, looks good. Dynamic creation of interference patterns (rather than relying on film to reproduce the patterns) seems like a necessary step to get useful animated holograms...

as a dumb person I fail to see how this is an improvement over a parallax barrier- didn't the guy say "2 views"?

I didn't hear anything about "2 views" in the interview, only that the MEMS mirrors have two positions to reflect the light. The technique described seems to really be holographic (ie. interference of light), so you should have an infinite number of views.

If its holographic, it wont be 'two views' it will be 2 light sources at right angles creating a constructive/destructive interference pattern (aka, a hologram). So will have many advantages over autostereoscopic (multiple viewers, multiple views, no head tracking required).
