Tech: SALT grain-sized camera can take crisp, full-colour images like 'lenses 500,000 times larger'

Despite being the size of a grain of salt, a new microscopic camera can capture crisp, full-colour images on par with normal lenses that are 500,000 times larger. The ultra-compact optical device was developed by a team of researchers from Princeton University and the University of Washington. It overcomes problems with previous micro-sized camera designs, which have tended to take only distorted and fuzzy images with very limited fields of view. The new camera could allow super-small robots to sense their surroundings, or even help doctors see problems within the human body.
