    This Laser Can Create 3D Holograms In The Daylight
    by Steven Tweedie

    If you've seen "Star Wars," chances are you've seen the futuristic hologram projectors that create three-dimensional images in the air.

    While we're still far from seeing a person projected onto thin air, a new holographic display from Japanese firm Aerial Burton is getting closer, according to Geek.com.

    Aerial Burton's display is incredibly promising thanks to its ability to project three-dimensional images onto thin air using highly focused pulse lasers.

    While similar methods have worked in water and fog in the past for a more detailed image, Aerial Burton's technology doesn't require water, mist, or fog, meaning you can see its holographic projections using air as the medium.

    Here's how it works.

    The machine uses a 1kHz pulse laser and sends the laser through a 3D scanner, which reflects and focuses the laser onto an exact place in the air above. The laser ionizes the air's molecules in that specific spot, which results in the flashes of light that make up each point.

    For now, Aerial Burton's display is "low resolution," meaning it's capable of only basic shapes, but the team is working on finding a way to create more-complex images while using air instead of fog, which is tougher since air is far less dense.

    Aerial Burton is hoping to market its technology to be used during emergencies, as the highly visual holographic display could alert citizens and potentially direct them to safety. The team is also hoping to shrink the laser technology necessary so it fits inside of a car, allowing it to stay mobile.

    NO,

    It does not create a hologram.. It creates an ionized burst of plasma at the point of focus.

    While a cool effect, it needs a ridiculously expensive laser with very high peak powers.

    On the other side of the plasma, away from the laser, is a large amount of unsafe laser light.

    The plasma is not transparent, so you cannot create grey scales nor form more then simple shapes.

    There is a an annoying snapping sound when each burst of plasma forms.

    It might have its uses at Theme parks or in malls, but it will never achieve practicality as a safe display medium.

    I've spent several years of my life around such plasmas.

    *YAWN*

    This AGAIN.

    This has to be at least 2012 news doesn't it?

    You are using Bonetti's defense against me, ah?

    I thought it fitting, considering the rocky terrain.
