DailyDirt: New-Fangled Cameras

from the urls-we-dig-up dept

Advances in imaging technology abound these days, and there are some pretty interesting cameras out there. Not too long ago, Lytro introduced a new type of camera that lets users change the focus after the image is captured. It uses an array of microlenses on a digital image sensor to capture all the light fields within the area of the scene. Then, with special software, users can adjust the focal point of the image after it has already been taken. Here are a few more examples of some cool new imaging technologies. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!) Techdirt post via StumbleUpon.

    Important detail on the graphene sensor: (quoted from the link below) "But in the paper detailing their work, the researchers actually reported that the photo-responsivity (with high photoconductive gain) of the graphene sensor was three orders of magnitude greater than other graphene-based imaging sensors.]"

    Emphasis on 'other graphene-based imaging sensors'.

    Great. More toys for the NSA and FBI.

    Bell Labs still exists?!

    I thought AT&T killed it a long time ago....

    I call BS

    "the sensor is 1,000 times more sensitive to light than imaging sensors found in today's cameras"

    But typical CCD and CMOS sensors are have quantum efficiency in the range of 10% (cheap camera phone) to 95% (liquid-nitrogen-cooled back-thinned CCDs).

    100% QE means you're detecting 100% of the photons that hit the sensor.

    How exactly are they supposed to do 1000x better, then?

    I call BS.

    I agree.
