Revolutionary ultra-thin 'meta-lens' enables full-color imaging

Light of different colors travels at different speeds in different materials and structures. This is why we see white light split into its constituent colors after refracting through a prism, a phenomenon called dispersion. ...

Fish-eye lens may entangle pairs of atoms

Nearly 150 years ago, the physicist James Maxwell proposed that a circular lens that is thickest at its center, and that gradually thins out at its edges, should exhibit some fascinating optical behavior. Namely, when light ...

Novel system mimics focus activity of the human eye

With aging comes deteriorating vision. At SIGGRAPH 2018, attendees will have the chance to test a new computational system that effectively mimics the natural way the human eye corrects focus, specifically while viewing objects ...

Delivering VR in perfect focus with nanostructure meta-lenses

If wearing a virtual reality or augmented reality headset is ever to become commonplace, hardware manufacturers will need to figure out how to make the devices small and lightweight while ensuring their images are sharp and ...
