Sorry for the typos. That text was an image, so I had to retype it.


"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."
