The Morning After: Friday, June 23rd 2017

Welcome to your Friday morning. As we prepare to phone in the rest of the day, read about how a lensless camera is possible with math, how car buyers aren't quite sold on autonomous vehicles, and how one company's working on a Photoshop for your voice. While phones get thinner, there's one spot that keeps sticking out: the camera lens. Taking good pictures and being able to focus at multiple distances requires a layer of glass that's a certain size, but there's really no getting around it -- or is there? Researchers at Caltech have devised an "optical phased array" chip that uses math as a substitute for a lens.
