Camera size of a grain of salt created by researchers
December 01, 2021

Princeton University and University of Washington researchers have developed a camera the size of a coarse grain of salt.

The system relies on 'metasurface' technology, which is studded with 1.6 million cylindrical posts and can be produced much like a computer chip.

It can produce full-colour images on par with a conventional compound camera lens 5,00,000 times larger in volume.
