This is the news article from Rice University: http://www.media.rice.edu/media/NewsBot.asp?MODE=VIEW&ID=8912&SnID=60786 67 The concise explanation is stated as: "In the single-pixel camera, the image from the lens is shined onto a digital micromirror (DMS) and bounced from there through a second lens that focuses the reflected by the DMD onto a single photodiode (PD). The mirrors of the DMS 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 [I would have said 'records' or 'encodes'] 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." Okay, so my guess is that the "missing piece" in this explanation is that somehow that (pseudo-)random sequence used by the DMD in the camera needs to be duplicated at the decoding end. Then at least it's clear that information isn't being thrown away. So my guess is that you need a time sync and knowledge of the pseudo-random sequence, from camera to display.
