Making a Perfect Cat’s Eye

Facebook X LinkedIn Email
LONDON, Dec. 1, 2008 – Recent research into the development of invisibility devices has spurred two physicists to investigate the process by which the behavior of light overcomes the seemingly intractable problem of optical singularities. According to these physicists, this could soon lead to the manufacturing of a perfect cat's eye. Unlike humans, cat’s eyes appear to glow in the dark because of their ability to reflect light from all directions. They are effective because they can send light back from where it came, but while this works well for light from some angles, it doesn’t work well for all. When...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
