  • My future.. display thingy.

    3D plasma shapes created in thin air


    The night sky could soon be lit up with gigantic three-dimensional adverts, thanks to a Japanese laser display that creates glowing images in thin air.

    The display utilises an ionisation effect which occurs when a beam of laser light is focused to a point in air. The laser beam itself is invisible to the human eye but, if the intensity of the laser pulse exceeds a threshold, the air breaks down into glowing plasma that emits visible light.

    I seem to remember (hope?) such things are prohibited/vastly limited in most places on Earth...

      Nifty, but rather sure they are prohibited as well. Mostly to do with air traffic and such, at least in certain areas.
