An ultra-compact metasurface camera, equivalent to the size of a coarse grain of salt, has been developed by researchers at Princeton University and the University of Washington. This creation could allow for small robots to sense close-proximity surroundings and potentially help doctors detect problems in the human body.

This metasurface camera has limitless potential, having overcome past problems whereby it captured distorted and fuzzy images with a limited field of view. Now the camera can produce crisp, full-color images on par with that of a conventional compound camera lens, 500,000 times larger in volume.
