Origami Optics at SIGGRAPHThe origami optics developed at UC San Diego may be what it takes to get cameras with zoom capabilities so slim that they fit into cell phones and other portable electronics. Electrical engineering Ph.D. student Eric Tremblay, one of the developers of the origami optics technology, presented his team's recent work at SIGGRAPH. The origami optics get their name from their ability to "fold up" incoming light so that the space required for light focusing -- the focal length -- is effectively reduced. The design "folds" the light entering the aperture by forcing it to bounce back and forth between mirrored surfaces within the optic. It is during this bouncing/folding that the light is focused, thanks to precisely cut reflective surfaces. This work is from the lab of Jacobs School electrical engineering professor Joseph Ford. It began as a DARPA-funded project for creating new kinds of optics for applications such as unmanned surveillance aircraft and infrared night vision technologies.Read more:http://www.jacobsschool.ucsd.edu/pulse/spring2007/cover1.shtml
