In Greek mythology, Argus Panoptes was a giant sentry with a hundred eyes. In the lab of Electrical Engineering Associate Professor Marc Christensen, Panoptes is a camera technology that combines images from dozens of tiny lenses to focus on a big picture.
Lens performance tends to improve with size, which is why a small cell phone camera can’t produce a very good image. Panoptes uses a computer to combine overlapping images from the small lenses to produce a clear photo without the size and weight of a large lens.
The technology is being developed with funding from the U.S. military for surveillance by small aircraft at low altitudes. The research should eventually provide helmet-mounted surveillance equipment for soldiers on the ground.
Christensen, chair of the Department of Electrical Engineering in SMU’s Lyle School of Engineering, has built a nationally recognized research group in photonics and computational imaging. His work with imaging sensors and micro-mirror arrays has been funded by the National Science Foundation and the Defense Advanced Research Projects Agency (DARPA), among others. In 2007 he received the DARPA Young Faculty Award.
