How thin can a camera be? Very, say Rice University researchers who have developed patented prototypes of their technological breakthrough. FlatCam, invented by the Rice labs of electrical and ...

WASHINGTON—Researchers have developed a thin lens with a continuously tunable focal length. The new lens could one day make visual fatigue from augmented and virtual reality (AR/VR) devices a thing of ...

While working on a high-tech imaging project, Professor Dominic Zerulla and his nano-optics team at the University College of Dublin (UCD) discovered something unexpected.

Light of different wavelengths travels at different speeds in different materials and structures. But an ordinary lens cannot focus light of different wavelengths to a single spot due to dispersion ...
