Matchbox-sized Laser Projector 291

Posted by CmdrTaco from the why-am-i-struggling-to-believe-this-one dept.
soupisgoodfood writes "Light Blue Optics Ltd. have developed a laser-based projector called the PVPro. It's small enough to fit into a cellphone or PDA. Some specs: Supports resolutions up to 2048x1280; No moving parts; Infinite focus; Green monochrome, with a colour version expected late 2006; Max consumption of 1.4W with an average of <350mW. Looks a like a good solution to the increasing problem of smaller devices trying to display more information."

For some reason, the human eye perceives some red in the violet (the sensitivity function of the red detecting cells is bimodal with a small bump in the violet)... so as long as there is some red in your image you could compensate it by lowering the amount of red but you won't get true-blue.

          Old school projector bulbs do get bright enough do use with modern projectors. There are still two problems with them though. First, the light is not white at all, it tends a lot toward yellow, which is unacceptable for a color projection. Second, to deliver that much light, they draw anywhere from 600-900 watts. That hurts in two ways, heat, which puts a strain on size and cooling methods. People don't want that much noise in their living room. It also cuts into the only advantage, which is cost. 600 watts vs 200 watts will cost an extra $180 in electricity over 3000 hours at .15 cents per KiloWatt Hour. So there really is no advantage at all. They are the best technology for the purpose. Don't you think if there was something better in an up and comming market like this someone would be selling it?

    Some news stories don't need them, but anytime a press release comes out about some new visual technology (eInk, laser projectors, etc), I get annoyed that they can't show the technology being demonstrated. Sounds more like vaporware and a company trying to get investors excited to dump millions into them before finding out the technology isn't feasible and walk away with those millions leaving the company bankrupt.

    Rant aside, if this technology DOES exist, it is very cool. Integrating a projector into mobile devices or notebooks is great, but considering the resolution, it would a great Home Theater projector as well. Laser light remains strong and bright over long distances, so in theory, you should be able to get big screens in the home without worrying about dimming the image.

    The only thing I worry about is that while having a high resolution, laser is such a highly focused light that will these "pixels" be too separated to offer a decent image? Even at 2000+ points across, if those points are spread out too far apart, then you won't get a decent projected image. Chances are, mobile applications where you can shine the image a few inches or feet away is probably all that laser projectors are good for. Throwing the image across 20 feet, while still bright, might separate the pixels too much and make for a poor image.

    So far, it looks like this company is just looking for investors, and as such, I would consider this vaporware. They are definitely looking to bank off the success of iPod video devices as well as the current fad of displaying television on Cell phones.

      I doubt it is pulsed - the laser is probably on continuously at variable amplitude. So, the pixels will just blur into each other. This is how a regular TV works as far as I understand. If you look at a TV you see lots of dots, but the reality is that the bandwidth on a standard TV is not sufficient to go from black to full RGB in one pixel - which is why small-fonts on TVs look horrible (it is also why analog TV is described in terms of lines of resolution and not columns - only the lines are discrete). A computer monitor is more expensive than a TV because it actually achives high bandwidth and consequently truly high resolution.

      My guess is that with the laser projector each pixel will really be a horizontal dash. The only place you might get separation would be in the vertical direction, but you get that even with normal TVs and it isn't very noticable. If you fired it against a screen that would scatter the light somewhat then it might help in this regard.

Shine a laser pointer at the wall, and it looks like the dot sparkles. I believe this is a function of the coherency of the light plus the way our eyes perceive the light.

    I can find little information on the companies website. They claim that it has "no moving parts", and that it uses "Computer Generated Holograms" and that it uses some kind of micropixel display.

    They say that because they can focus the laser so well, the computer generated hologram can be very small.

    They say that the system works by "steering light" instead of blocking it (an LCD array blocks light to modulate it).

    Anyway, none of this tells me very much. Are they using a piezoelectric mirror to scan a laser across a hologram, that bends the light to scan the image? Are they using a 1D mirror or LED array and then scanning that with a piezoelectric mirror/hologram? I assume that a piezoelectric mirror moves so little and so robustly that it's not considered a "moving part".

    What is the particular brand of magic that these people are using?

    "It uses 350 mw."

    Three Hundred Fifty Milliwatts is 0.35 of one Watt. Most lasers are under 50% efficient. The deflection and modulation and optics are unlikely to be more than 50% efficient.

    So imagine spreading 0.090 watts of light over a screen-sized area. Pretty dang dim! Like you'll need dark adapted eyes to even see the picture.

    Still a neat device, but you're not going to run your own Drive-in movie theater with it.

Program a cellphone to automatically accept/answer a call/image from a certain number, and attach it and one of these thingers to a remote-controlled car (either by Duct Tape or actually affixing it, depending on how quick you want to throw this together.)
