Origami Optics Promise Better Spy Cameras

The cameras in cell phones and robot spy planes could become more powerful by using optics folded like origami, researchers report. To zoom in on distant objects, professional cameras use telephoto lenses. These conventionally must be super long ?to bend and focus light. Since cell phones are small, they can...
