Camera Takes Single Pixel To Megapixel Resolution

Scientific American has an interesting article on an experimental camera Kevin Kelly and Richard Baraniuk from Rice University have invented. Basically what it does is use a single pixel, and a tiny chip covered with hundreds of thousands of mirrors to recreate the image. The technology could eventually be used to create high resolution pictures outside the visible light spectrum, where large arrays of detectors are cost prohibitive. The magic of the camera is that it in effect takes a compressed snapshot, then uses mathematics to produce the image later. Current cameras take a super high resolution image, then compress it, which uses up limited battery and memory space. You can see all the details at the camera's homepage.
