Light filtering technology developed with funding from the U.S. Air Force Office of Scientific Research may one day allow warfighters to see more clearly through clouds, dust or other obscurants. The technology could lead to a circular polarization camera capable of improving intelligence, surveillance and reconnaissance technologies that would boost situational awareness on the battlefield or for homeland defense. It also could aid cancer detection and even enhance 3-D movies.
