Stretching out: graphic showing how a time lens can distinguish between two photons arriving at a detector close together. (Courtesy: Optica) A new “time lens” that can magnify the difference in ...

Using a single lens that is about one-thousandth of an inch thick, researchers have created a camera that does not require focusing. The technology offers considerable benefits over traditional ...

Liquid crystal (LC) lenses with electrically tunable focal length have attracted much attention for their potential in ophthalmic applications, three-dimensional displays, cell phones, virtual reality ...

A flat lens that allows a camera's focus to be maintained for objects separated by distances of up to six meters could offer benefits to smartphones and mobile devices, including the potential removal ...
