Sorry for the typos. That text was an image, so I had to retype it. http://www.media.rice.edu/media/NewsBot.asp?MODE=VIEW&ID=8912&SnID=60786 67 "In the single-pixel camera, the image from the lens is shined onto a digital micromirror (DMD) and bounced from there through a second lens that focuses the light reflected by the DMD onto a single photodiode (PD). The mirrors of the DMD are shuffled at random for each new sample, creating random patterns of black and white, as depicted in this schematic. Each time the mirrors shift, a new pixel is recorded by the photodiode. The camera creates an image by capturing just one point of light, or pixel, several thousand times in rapid succession. The thousands of single-pixel snapshots are then assembled by a computer into a high-resolution image."
