Engineers have developed a type of camera that doesn’t require any lenses. They’re replacing curved glass with something that does the same job computationally – an ultra-thin optical phased array.
Researchers hope that the findings could turn a wide range of flat surfaces into image collectors.
To capture the perfect selfie or Instagram photo, cameras use lenses. In digital cameras, the lenses are used to focus the light on to a digital sensor. The optical phased array has a group of light receivers that adds a minute delay to the light as it is captured. This allows the camera to switch focus and look in different directions using nothing but electronic trickery.
