Engineers at UC San Diego have built a powerful yet ultrathin digital camera by folding up the telephoto lens. This technology may yield lightweight, ultrathin, high resolution miniature cameras for unmanned surveillance aircraft, cell phones and infrared night vision applications. Credit:...
The emerging field of astrophotonics shows promise in analysing light from the night sky. Future telescopes, with mirrors half the size of a football field, will need special components to deal with the light they collect. Astronomers are turning to photonic devices that guide and manipulate lig...
