A Projection Display For Your Pocket

Posted by timothy on from the not-my-pocket-that-is-but-yours dept.

lub writes "The German Fraunhofer-Instituts für Siliziumtechnologie is developing a pocket beamer. It uses a laser beam and a rotating mirror to display the image. Another laser and a photo diode is used to verify whether the displayed image is shown correctly, so the electronics can adjust the image when the beamer moves. No colors yet; 320x240 in nice shades of red is what they have now, but higher resolutions and color might be implemented later. I want this in my BlackBerry!"

    God I even previewed it... should previewed the preview.
    Anyone else wondering how they got black on the white sheet of paper with a red laser in the image of this device in TFA? :)

    That;s pretty 'zucking' small.

    It's a monochrome laser projector with a scanning mirror. There is one of these in every laser printer. Except this one scans two dimensions. Then again, its 320x200 instead of 5100 pixel line scanned by a 600dpi letter-size printer. So its not a big deal. Besides, wasn't there, back in 1998 or so, some 3D stereo display for some game console that used a red scanning laser? I think I've seen one in K-mart. I suppose, noone wanted a monochrome display then, and noone will want one now.

    So the interesting thing about this gadget is not the amazing fact that someone made a laser projector, because there really is nothing amazing about it. The interesting thing is whether these guys would ever get 3 lasers (especially the blue one) cheap enough, while powerfull enough to scan a highres picture, as large as an LCD projector does, onto a wall. They'd need 3 powerfull lasers. As light sources go, lasers are about the least efficient, so the gizmo would drain a lot of power, and it will have to be large, with the heatsinks, fans, an all. So, the gadget would really end up being at least as large as an LCD projector, and some 10 times more expensive, mostly because of the blue laser. Why bother?

    Wow, it has the ability to project red and BLACK light onto a bright white surface!
