Three Dimensional Images in the Air.
AIST ^ | February 7, 2006 | press release

Posted on 02/24/2006 6:04:52 AM PST by Bloodclot

Key Points

1. We have used laser produced plasma technology to make a flashpoint in the air.

2. We have greatly improved the brightness, contrast, and production distance of the plasma by optimizing the laser beams.

3. Using a laser plasma, we have been the first to succeed in displaying "real 3D images" in a space where there is nothing but air.

Synopsis

The National Institute of Advanced Industrial Science and Technology (AIST, President: Hiroyuki Yoshikawa) and Keio University (President: Yuichiro Anzai), in collaboration with Burton Inc. (CEO: Hidei Kimura), have succeeded in the experimental fabrication of a device displaying "real 3D images" which consist of dot arrays in space where there is nothing but air.

Most of the 3D displays reported until now draw pseudo-3D images on 2D planes by utilizing the human binocular disparity. However, many problems occur, e.g., the limitation of the visual field, and the physiological displeasure due to the misidentification of virtual images.


Figure 1 A 3D-object displayed using a 3D-image spatial drawing device we have developed.

The device we have developed utilizes the plasma emission phenomenon near the focal point of focused laser light. By controlling the position of the focal point in the direction of the x-, y-, and z-axes, we have succeeded in displaying real 3D-images constructed by dot arrays in air (3D-space).

Background of our Research Work

Our living space is three-dimensional, and all the things which exist therein are also three-dimensional objects. Of course there is an abundant amount of information on 3D-images on the Internet, but we hardly ever see "real 3D-images" reproduced from this electronic information. This is because we have no electronic devices enabling us to display real 3D-images.

In fact, some 3D-displays enabling us to deal with 3D objects have been reported, but most of them display pseudo-3D objects on 2D devices by utilizing the human binocular disparity, inducing many problems which it is essential to rectify, e.g., the limitation of the visual field, and the physiological displeasure due to the misidentification of virtual images. History of Research Work

Keio University and Burton Inc. noticed a phenomenon that, when laser beams are strongly focused, air plasma emission can be induced only near the focal point. Thereby, they succeeded in the experimental fabrication of a device displaying 2D-images in the air, which are constructed from dot arrays produced using a technique combining a laser light source and galvanometric mirrors. To further form 3D-images in the air, the scanning of the focal point in the depth direction along the laser optical axis is essential. However, for such a purpose, the quality of the laser and the technique for varying the position of the focal point must be improved, and thus as yet there are no 3D display devices.

Details of Research Work

The AIST, Keio University and Burton Inc., in cooperation, have succeeded in a spatial display of "real 3D images" consisting of dot arrays using a device which is made by additionally incorporating a linear motor system and a high-quality and -brightness infrared pulse laser into the 2D display device mentioned above.

The linear motor system enables the position of the laser focal point to be varied by high-speed scanning of a lens set on the motor orbit. Incorporation of this system makes the image scanning in the direction of the z-axis possible. For scanning in the x and y axis directions, conventional galvanometric mirrors are used.




Figure 2 Overview of the 3D-image spatial drawing device we have developed.

The laser light source we used in this work is a high-quality and high–brightness infrared pulsed laser (repetition frequency of pulse: approximately 100 Hz), by which plasma production can be more precisely controlled, enabling brighter and higher contrast image drawing. In addition, the distance between the device and drawing points can be greatly extended (several meters).

The emission time of the laser pulse light is on the order of a nano-second (10-9 sec). Our device uses 1 pulse for each dot to that the human eye can recognize plasma emission by utilizing the after-image effect, and enables a 100 dot/sec display.

By synchronizing these pulses and controlling them with software, our device can draw any 3D objects in air.

I attended the Consumer Electronics Trade show in Chicago back in the 70s. There was a company that had an object that looked like an aquarium with a 6 inch 3D girl walking around in it. You could reach in and put your hand right through her. The company spokesman said they were working on a 3D projector that would mount 3 laser projectors in the top corners of a room and where the beams would intersect, there would appear a 3D object. This was back in 1975. I've always wondered what happened to that research.

They were ordered by the feds to stop working on it and concentrate on the 100MPG carburetor.

Holodeck uses structural integrity fields and transporter technology to produce "solidograms". Holograms with apparent texture and solidity.

Still a ways away from that one. But I could see a Niven/Barnes type "Dream Park" that would completely revamp the theme park industry.

What's not clear is the timeframe of those pictures. If the camera was on "time" then the sparks could have been generated over several seconds.

I bet it's noisy- air discharges like that go POP! (I saw an orange-colored dye laser make air sparks at a tight focus and it went BANG! The laser was named LIBOFORS).

The power of the laser is not mentioned- it won't be insignificant if it can be focused to the point that it can ionize air. Gotta be Class IV, don't try this at home.

Yet it's a start, and a good start!

Obviously this isn't new.

We all saw it on 911 as holograph images of planes were projected to cover the missle attacks on the WTC.

Note; I actually read that yesterday.

So this is how they faked the attack on the WTC on 9/11. Everyone knows Bush did this on purpose...

Do I need a sarcasm tag?

I knew about this months ago, and informed Pentagon at that time. This should have been kept off of public eyes, risking chance of spreading the words to unwanted people.

Okay, this is for those who believe in extraterrestrials. I think I saw this on the Discover Channel on the UFO files. An alien abductee said while she was laying on an examination table she was surrounded by aliens who were watching a screen like image that was floating around the room and that it wasn't attached to anything. She said she could see through the image but couldn't understand what was on the screen but there were a multitude of colors and it moved to various locations in the room as to be observed from different direction. It appears these scientist may be on to the answer as to how the floating screen image might work.

..cause glow-in-the-dark soldiers made out of big floating spheres of blue light are going to be indistinguishable from the real thing in just a few years time. Really!

Actually it COULD work

If they painted all real soldiers with big spots of glow-in-the-dark paint, from a large distance and at nighttime, the holograms would be NEARLY INDISTINGUISHABLE from the real thing! LoL!
