- yocouchdigga, on 11/09/2009, -1/+20 I would find reasons to use this. Mass produce that ***** and prepare a TED Talk.
- tidu, on 11/09/2009, -0/+12ENHANCE...!!
- dtele, on 11/09/2009, -5/+16After reading the article, I still couldnt figure out how this could be done as the Gizmodo article claims, with "... no lens to speak of, as the magnification is handled entirely by software, holograms and electronics"
BULL!
I found the original article at http://www.nytimes.com/2009/11/08/business/08novel ...
FTA: “This is an inexpensive way to eliminate a microscope and sample biological images with a basic cellphone camera instead,” he said. “If you are in a place where getting to a microscope or medical facility is not straightforward, this is a really smart solution.”
BINGO - the microscope utilises the cameras lens!
And there has been NO PRICE set for these things... dont expect one for 10 bucks anytime soon. - Hefelumpman, on 11/09/2009, -0/+8except that your original article states the following
"“There’s no need for lenses in these devices because the magnification can be done electronically,” he said. “You don’t need optics at all.”"
and here http://www.wired.com/science/discoveries/multimedi ... it shows/explains that the sample is placed directly over the CCD - n1eb, on 11/09/2009, -0/+6They didn't really explain how it all works, but I'm guessing the sample is placed directly on the CCD and the big top hat looking thing is a backlight.

This will lead to tweets like: "i just coughed up some goop. does this look like streptococcus to anyone?" - dhughes, on 11/09/2009, -0/+4 Coming soon: Swine flu? There's an app for that.
- robwhite1979, on 11/09/2009, -0/+4LMAO... On facebook: "You have tagged a photo of herpes simplex-b. Would you like to publish these photos now so your friends can see them?"

- orvl, on 11/09/2009, -1/+3Umm... excuse me but I think that was meant to be totally obvious...
The picture at the head of the article on Gizmodo clearly shows the modification being done directly over the camera part of the cellphone.
I think the Giz editors assumed their readers were intelligent enough to realize that the quote "... no lens to speak of, as the magnification is handled entirely by software, holograms and electronics" is referring to the fact that the microscope modification doesn't require the addition of any expensive magnifying lens over the cell camera.
Did you think at all before posting your "BULL!" comment? ROFL - jmptexas, on 11/09/2009, -1/+3dude must know algebra and stuff.
- siggyfawn, on 11/09/2009, -0/+2Nice appendage. This phone has the "are you happy to see me" joke built right in.
- linagee, on 11/09/2009, -0/+2This is kind of cool. You could use the cell phone to take pictures and send it to a lab with more expertise in how to decipher what you see. (Especially if it's in 3rd world countries and a real research institute may be in the next nearest city.)
In addition to tele-photography, you can have software itself understand what it's seeing and analyse things. - krymson, on 11/09/2009, -0/+1Truly awesome *****.
I like diggs' novelty post as much as the next bloke, but I do wish more news like this popped up on the Front page. - TexMexRex, on 11/09/2009, -1/+2The article is a little short on information. I'm going to take a wild guess and say he is removing the lens from a cell phone cam, and placing the sample directly on the image sensor, then dumping a whole lot of light on top of it.
How this involves Holograms??? My guess is in trying to dumb down the tech speak, the term hologram was introduced in place of 3-D imaging or something. - krymson, on 11/09/2009, -0/+1Saw this on NYTimes this morning. Don't know why that article didn't make FP but the Gizmodo one did.
- Cornsky, on 11/09/2009, -3/+4I'm claiming it first... www.homemadebacterialporn.com
- lbzfoxracingsmp, on 11/09/2009, -0/+1I have always wanted to see if the fish in the snow were doing ok.
- Verytastycheese, on 11/09/2009, -0/+1I find this ridiculously hard to believe...
- darkane, on 11/09/2009, -4/+4Buried as Gizmodo spam.
- tanvach, on 11/09/2009, -1/+1Don't know how it's implemented in reality, but I'm guessing it records the diffraction pattern from the blood cells (the hologram) and then guesses the image on the slide by using something similar to a phase retrieval algorithm (http://en.wikipedia.org/wiki/Phase_retrieval). It's similar to calculating the widths of the double slit experiment knowing only the diffraction pattern.
Not hard but takes a lot of computation power. We use it all the time in our adaptive optics setup.
It's cleaver because he uses cell phone imager that is not really suited for something like this. - jmptexas, on 11/09/2009, -1/+1you sound wrong. very wrong.
- Philippeog, on 11/10/2009, -0/+0Wow amazing... I'm actually working on implementing a Toaster on a Cell Phone.
- TexMexRex, on 11/09/2009, -1/+1I hope English is a second language for you.
- Seronis, on 11/09/2009, -1/+1Buried for not linking to the original article
http://www.nytimes.com/2009/11/08/business/08novel ... - frsrblch, on 11/09/2009, -4/+3My Bachelor's of Science in Materials Engineering from a major Canadian university was $25 000.
- lews001, on 11/09/2009, -7/+2Guess I got a deal on the degree....
