Traditional cameras require a lens or pinholes to focus light onto a sensor, which makes them bulky. This would eliminate that protruding camera lens from the back of cellphones. Professor of Electrical Engineering at Caltech Ali Hajimiri says that it could be made thinner than paper. Hajimiri explains the optical phased array system by comparing it to a…
