The mobile camera of the future will not have focus lenses
Whenever Manufacturers try to reduce the thickness of their phones, there is always a component that determines the thickness of the body. It is the camera, a set of quality is composed of a series of insalvables optical elements that need a minimum space to capture the scene correctly. But all that can be changed,The researchers at the California Institute of Technology designed a phased optical chip using mathematics to get an approach without lenses.It adds a latency time (up to one quadrillion of a second) to the light that is received in the different zones of the chip, something that allows to adjust the focus without needing any lens.
According to Professor Ali Hajimiri , the chip is able be converted from a fisheye to a telephoto lens instantaneously, only through changing the way the chip receives light. In 2014, the team already introduced something similar , as they wanted to show how to create a small projector inside a phone, although there is also another application that shows that we could turn the phone into a very powerful 3D object scanner.
