A new technique for revealing images of hidden objects may one day allow pilots to peer through fog and doctors to see more precisely into the human body without surgery. Developed by Princeton engineers, the method relies on the surprising ability to clarify an image using rays of light that would typically make the image unrecognizable, such as those scattered by clouds, human tissue or murky water. In their experiments, the researchers restored an obscured image into a clear pattern of...

U.S. scientists say they have developed a new algorithm that may advance data encryption capabilities. Researchers led by Princeton University Assistant Professor Jason Fleischer developed the so-called reversing algorithm after using a special optical device called a non-linear crystal, rather than an ordinary lens, to capture an image. Every image is made up of a collection of light waves, and a lens bends (refracts) the waves towards a detector, the scientists explained. In contrast, in...

When photographers zoom in on an object to see it better, they lose the wide-angle perspective -- they are forced to trade off "big picture" context for detail. But now an imaging method developed by Princeton researchers could lead to lenses that show all parts of the scene at once in the same high detail. The new method could help build more powerful microscopes and other optical devices."It allows you to take a closer look at an object without narrowing your field of view," said Jason...
