Why do point-and-shoot and digital SLR cameras deliver better quality pics than smartphone cameras? One reason is the size of the imager, but another important factor is the size of the lens. Now, researchers at the Harvard School of Engineering and Applied Sciences have figured out a way to revolutionize lenses, making them as thin as a sheet of paper.
The 60-nanometer-thin lens is built around a gold-plated silicon wafer, and by chipping away part of that wafer to create rows of V-shaped structures, somehow (insert miracle here) that lens can capture wide-angle images with virtually no distortion. Someday, this technology might enable super-thin smartphone cameras to shoot photos that are just as good as those shot with today's bulky digital SLRs.
