Cameras that could replace your eyeballs

Scientists have develop a camera that ’s as flexible as an eyeball with all the zooming power of a conventional camera . And it ’s only the sizing of a nickel .

In principle , a camera operate like a human eye . ignitor moves through the camera lens of the eye into a hollow structure , which focuses that light and resolves it into an image . But the human eye has one thing cameras do n’t : The ability to distort its lens , using the muscles of the center . These muscles can tighten around the lens until bulges or stretches , which allow your middle to concenter on near and far objects . In other tidings , your eye can do with one lens what it takes cameras several lenses to do . It can adjust to see close up and far away , or to take in a encompassing electric discharge and examine a midget orbit .

Cameras , on the other deal , can do something the eye ca n’t do : Zoom . Once the center has pore , it ca n’t see an up - tight version of the image it ’s sharpen on . That ’s the camera ’s specialty . By adjusting the distance between your photographic camera ’s lenses , you could zoom in and out until it accomplish a focused close up from twenty feet away . The trade off for this is a lot of mass , in the form of the many lenses and the apparatus necessary for move them around .

This new camera uses the best of both worlds . It has a flexile lense and a compromising level of photo - detector . Both are controlled by hydraulics , or precisely - put in volume of weewee , to contort the tv camera ’s lenses much the way that muscles distort the eye . And the photo detectors at the back of the tv camera ’s middle can also distort and zoom in on images in a way your eyes ca n’t .

The camera can be brought down to the sizing of a nickel and will look like a little half - globe . Scientists think that it will vastly expand robotic sight , and the accuracy of endoscopic aesculapian procedures .
