Volumetric video, how could it work?

    There is only the hint: lasers. Maybe the air is pre-ionized? Or made
    very turbulent?

    And how could you make the air ionized?

    High voltage wnd point emitters, or UV light.
    Maybe they use a fog...

    The display is not volumetric. It is planar, like a regular screen. The only
    unique thing about it is the fact that the image floats in midair.

    Here's an interesting link on ionized laser pathways, don't know if it's

    The "O2" in their name implies something to do with ionized air and ozone,
    perhaps artificial smog, but it would have to be very minute quantites as
    smog is harmful to lungs.

    Here's another very interesting document describing Rayleigh scattering of
    lasers, which can be calculated based on the temperature and pressure of the
    scattering medium. Rayleigh Scattering J Meas Sci Tech.pdf

    I have one other theory that is based on much simpler physics: the device
    supposedly modifies the air going through it, without adding anything. That
    rules out fog liquid or water. My guess is that the device is a heater
    designed to produce a laminar flow with a very sharp temperature boundary.
    This boundary could have refractive effects that bend projected light toward
    the viewer. A very common demonstration of this effect can be seen as
    water-like mirages on sun-heated paved roads, caused by sharp temperature
    boundaries near the surface of the road.
