3D plasma shapes created in thin air

<a href="http://www.zephnet.com/">www.zephnet.com/</a> ?select=squib&league=composite&post_id= 69162&docket=1&linkoff=6 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 system is being developed by the National Institute of Advanced Industrial Science and Technology (AIST) in Tokyo, in collaboration with Burton Inc and Keio University. “We believe this technology may eventually be used in ap-plications ranging from pyrotechnics to outdoor advertising,” says a spokesman for AIST. According to Burton Inc, the technology might also be used for emergency distress signals or even temporary road signs. 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. The required intensity can only be achieved by very short, powerful laser pulses – each plasma dot, or "flaashpoint", lasts for only about a nanosecond. But the resulting image appears to last longer due to persistence of vision. As with film and television, the impression of a continuous image is maintained by refreshing the flaashpoints. Zap, crackle and pop The demonstration system uses an infra-red laser that creates a hundred flaashpoints per second. Currently, these can be projected between two and three metres from the apparatus, in a space of about a cubic metre. Each flaashpoint generates a popping sound, resulting in a constant crackling when the display is in operation. Previous systems used galvanometric mirrors to control the focal point of the beam in two dimensions, to create only 2D images. But the new system adds a high-speed linear motor moving a lens to also control the focal point of the laser in a third dimension, allowing solid shapes to be sketched out. The researchers behind the demonstration system plan to upgrade it to a higher pulsing rate, which should produce more dots and so smoother images. Future versions should also include moving pictures and AIST claims it should be possible to scale the system up to produce displays of any size. However, only white flaashpoints can be created so a colour display will not be possible.

Just in time for the Rapture! *Very* interesting.

Or a candid view of Uranus??? <img src=http://www.ezboard.com/images/emoticons/alien.gif ALT="0]"> <img src=http://www.ezboard.com/images/emoticons/laugh.gif ALT=":lol">

Good point, Professor. Time for Maitreya to "appear" to the masses! Or perhaps some aliens?

ooohhh... somebody said the "M" word! The holographic imagery is available to create a UFO invasion, or the Rapture, or Maitreya in the sky. --MaryK

more trickery to rob your wallets,property and lives then the power elites will show up to provide food ,clothing and shelter at a "safe" location of course families will be separated with the state providing services for the kids and a different service for the adults at undisclosed locals...

Looking beyond the obvious appliance of such technology - The Matreiya etc are some pretty interesting points. But moreover, you zap a lazer at a fixed point in space, vibrate it to a certain resonance, and you can create a plasmic "illusion" Didnt Tesla deal with this kind of stuff - Creating something from nothing by altering certain vibrational frequencies ? Im obviously being slightly disingenuous here, since what is happening is that the vibrational frequencies of the cosmos are being decoded into a form that our pathetically limited perception of "reality" can actually see.
