Apparently it looked very realistic in person and on TV. So realistic that laser pointers seemed to terminate and reflect on to his body
What technology was used for this. People are already talking a Micheal Jackson tour with this technology. New or old?
suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
Its just ole "Pepper's Ghost" done with a new, specialized, coated, stretched plastic film or films and good quality video projectors.
They use "Holographic" as a marketing gimick. It is not a hologram, its a reflection. Note the required EXTREMELY dark background.
The film probably comes from 3M, as does the controlled scattering film used to allow video projection on glass windows.
So old a technology, they are counting on marketing and gimmickry and a lack of education in entertainment to call it "New" again.
The retired Imagineers at Di$ney who reinvented it the sixties when it came from the 1860s must be LTAO.
Although the high tech plastic is world class material. Nice to see it looks like their using mutiple layers, courtesy of the pointer, that was a little detail that was puzzling me.
Thanks guys, I figured it wasnt a hologram which is why I put it in quotes. If you look at it from different angels (ie right stage or left stage you seem to see more of his sides) Is this how Di$ney makes their ghost "the secret way" in their haunted house?
I did notice the darker background than the others. For once, some idiot in the crowd with a laser pointer actually gave us something useful
whoever did the video editing did a good job, i notice the usage of covering his mouth with the microphone as making the mouth movement would have been very intensive. It still looked very good from my amateur eyes
How long before we get Elvis?
Elvis has been and probably still is on tour.
I did lights for an Elvis tour a few years back.
They just used a big video screen to project Elvis onto and had a band on stage... Still sold out arenas though.
I thought it was a bit weird to be honest..
If in doubt... Give it a clout?
haven't the japanese been doing this forever?
Looks like they use a bunch of closely placed sheets to help with that.
There are coming soon, linticular sheets, so I can see depth of parallax going up.
I heard from someone I trust with their opinion and they said it looked pretty real in person
PJ'll be reaching for the tissues !!
Nice one Steve.
Full explanatory video as well:
For the best of "real holography" in 2013, consider a meter sized glass display cube on a pedestal. There is a single tiny light source on the ceiling aimed toward each of the four faces, like in a museum. The objects inside are in full color as expected of "real" things. How do you know the objects inside that cube have mass? You can't. The walls of the cube are holograms.
But there are some very interesting things an artist could do with subjects in a cube like that. Combine that with other projection tricks like the Pepper's Ghost. That's potential, but the reality is a box the size of a breadbox with a freakin' real image inside, using LED and/or despeckled laser light for illumination and the best full color recording materials available today. Throw the budget of a very large sculpture, or a reasonable film at it and one would probably make a splash as big as the Tupac nologram.
It looks like they have a very short distance to do the focussing, so could this make spatial filters more compact?
 It would make graphics lasers absolutely spot on - being able to focus and de-focus the beam to different sizes. Divergence modulation if you like. [/edit]
Neat display, but nothing compared to a real hologram.
About the focussing thing, I don't know how it's done, but it may be that more than one beam is used, scanned independently to converge on a point in space. The SSY1 rangefinder laser can make sparks in air if the Q-switch is used. Peak power is very high to ionize air. The lens might not have to take huge power but making a lens that can change focal length that fast seems to imply that it's not a mass with refractive index changing at all, but some field in something vaguely like an AOM. But it may be easier to use two or three beams, all below threshold on their own, but wherever they meet, and if at that moment the lasers are pulsed (I don't think any of this is CW), the result is enough ionization to be visible. That's maybe what the air based one is doing, but the water based one looks as green as the lasers that excite it, so I'm not sure what that means. Although maybe tiny bursts of vapour in microscopic bubbles, so could just be rayleigh scattering.
In all cases, it's huge amounts of energy, so I bet it won't be appearing in weird new domestic TV's.
