Randy Atkins:  Digital cameras replace film with millions of detectors—megapixels—that turn light into overwhelming numerical information.  Follow-up number crunching consumes lots of power.  So Richard Baraniuk, a Rice University electrical engineering professor, is suggesting a different way to record light.

Richard Baraniuk:  A two-dimensional array of millions of tiny little mirrors and these mirrors are able to flip, either this way or that way.

Randy Atkins:  Resulting in thousands of random patterns all sent to a single photo detector where…

Richard Baraniuk:  We add it all up with some fancy new mathematics that’s been developed over the last two years to be able to integrate that information together to get the final picture.
