A Video Projector That Fits In Your Pocket

Posted by timothy on from the princess-in-robot-tech dept.

Sven-Erik writes "Video projectors able to project high-quality images will be embedded in your cellphones and laptops within two years. This is the promise of a new technology developed at Cambridge University. These pocket projectors will have no lenses and no light bulbs. Instead, these future battery-powered tiny projectors will rely on holographic technology and special algorithms. In 'Holograms enable pocket projectors,' Technology Research News explains that a 2D hologram will be created on a microdisplay and projected by using a laser beam. This has been possible because the researchers have written special algorithms which generates the holograms a million times faster than standard ones."

      You know the funny thing is I remember thinking to myself the first time I saw that why the holographic video was grainy, it seemed preposterous to me that they could have that sort of technology on R2D2 and yet have it be all grainy in appearance.

      And now it seems incredibly prescient lol, given the millionfold increase in processing speed using the noise variance method described in the article, the trade off between graininess and speed actually becomes quite rational.

    The Pocket Projector - the sign of a true dork.

    Great. This only increases the potential of being able to have PowerPoint presentations shoved down your throat, now anytime, anywhere.

    PHBs beware, do not approve a purchase of one of these projectors for use by Debbie from Sales.

    It would be cool if it didn't suck.

You also can check hours of publication. I'm not happy with this. Last month, someone opened a Slashdot account with my name. Now, "Sven-Erik" is publishing my own words, already submitted to Slashdot, and he's credited for this. Slashdot editors, please be careful! And "Sven-Erik," please indicate your sources!!!
