How holograms are mades (with laser)

[Oduig]

An infinitely short period of time? Lol. That's not only untrue, but theoretically impossible. Every period of time can be cut into two parts.

Good story other than that.

[3DSCat]

last pic he had a United nations had on with flag and  the all seen eye.... eh..

[huggkruka]

It's still mysterious, god damn it! Showing us laserbeams and bleaching solutions is all good, but how does it WORK? What's the theory? I am no wiser now than I was before.

[horror478]

How do companies mass produce this?

[nomainreason]

I like it... I'd scare my neighbours, make them think the neighbourhood is haunted...

[14jswans]

Let's get the rating up!!!!

[qrfbsca]

Lol something called bleach

[58pianos]

Wow!! Get rid of that music. I'm here to learn, not to be entertained.

[sum420body]

great video, why is there over 200 idiots that hit the dislike button... what is wrong with you people, how do u not like holograms...

my guess is that 200 semi-retards probably thought this was fake...

[illneverforgetthe90s]

This is what our universe might be :D

[ishmaboy]

How the hell is this rated 2 stars?

[hovadoposrate]

Nice discovery 4 ever :D

[lavendardust]

thank you. have not seen that explained in visual details before.

[iloveyoujules]

nice and interesting video! :)

[TurbulenceXM]

so how can we see this technology be used in the future? I know people can buy holograms for their homes but what other ways can this technology be used as a consumer product? The video hologram he was showing at the end makes me believe this could be used somehow for the future.

[chagdud1]

Look up hologrpahic hard drives, they were supposed to be released last year, they will 1$ Hoplograpic storage cards will hold 120,000 gigs of data.

[TheMathGuy]

Technically, 12 nanoseconds wouldn't be an "infinitely short period of time". It's only a 12 nanoseconds short period of time! =P

[TheMathGuy]

OK, so I see that a hologram uses an interference pattern somehow, but how does that same interference pattern allow light to be reflected in such a way as to produce the original image? I know that with ordinary film, the surface reacts to the intensity of incoming light (getting darker the more light there is--and hence what you get is a negative), but how do you get a piece of film to reflect directionally asymmetric light? Is there something special about holographic film that allows this?

[Romovisque]

Holograms can be done

[ladymaggic]

Excellent explanation...clear voice and instructions.

Thank you...

[IAmSamThatIAM]

Ah! I looked straight at the green laser. I'm blind! That is cool.

[theycutheyknowu]

I think computers in the future will be hologram 3d technology like in the movie The Time Machine (2002) when the guy pops up in a glass frame giving guy peirce information online etc.

[Joo3l]

thats amazing!

[Tomas953X]

holograms?! MY BALLLSS

[Freedomfoe07]

I wonder if its possible if they make those same holograms like in the Star wars Movie

[Snappayy]

those are projected and arent supposed to be 2D that looks 3D, holograms are 2D that look like 3D

those kinds of holograms arent possible

[Colombian459]

Not yet.

[Snappayy]

exactly

[pdegameplayer]

the second is a solution called bleach? he says it like we have no idea what bleach is?

[backinorange]

The bleach solution in the video contains

1 liter DI water

4 milliliters concentrated sulphuric acid

4 grams potassium dichromate

not all bleach solutions are the same :)

[djaakash]

this is sweet...i just made one like this in my physics class!

[joy4u666]

very informative... helps to explain a lot of aero space

[cvm13]

thats a long process for making holograms like that... tha was fairly interesting...

[housemandoc23]

dyslexia is when letters appear out of order, not misspelled jack ass.

[kiwiportal]

suck my balls

[WildPhisherMann]

wait... wtf... the film is a hologram by itself?

[hboy007]

that was really cool :) well made

[DrMario2007baka]

spacecowboy22, It has to be rinsed in bleach, to remove the remanet of emulsifier, then rinsed by - yes - water (to remove any bleach left so it won't have any chance to eat emulsion that's already set.)

[spacecowboy22]

"and then its washed in a solution called Bleach" wow never heard of bleach before...

"and then its rinsed in clear water" WATER??? CLEAR??? GET OUT OF TOWN! lol nice vid

[muziklvr101]

xD lol

[knop95]

Help me Obi Wan Kenobi, your my only hope...

[DrMario2007baka]

Quit whittling, everyone. You can create it yourself, it's basically a photograph, only with laser energy being used like a flash - I have been to holography class, so it prove that you can make it! It's a tricky setup, though - if you didn't get it perfectly, it's because you're farting (the vibrations just mess the detail up) - it's simple as that. So, what's next, optical holography?

[southrnr64]

zwanphony i stupid moron this is not a fake video photoshoping a whole clip is nearly imposiable and if u can it turns out like a japinese movie converted into english

[ichsuka]

nope holograms are real

they are quite old in fact. and very common, you can make one yourself if you know how, check wikipedia

[RaulWesche]

That is an OLD one......

[dillonchamberlain]

how its made is a fairly cool show. but they need to have more interesting stuff like this on more often

[paddlepiddle2]

obviously a cool trade but thought I was in for luke skywalker shit

[flakelorenz02]

Help me Obi Wan Kenobi, your my only hope...

[rubbadude]

ROFL

[viperkyle1]

Lol, Random

[jinalo]

of course this is real how ever it's on a flat surface the hologram projected on air isn't possible yet want to know why research it...i'll make it possible one day

[TrumpetDude12]

thats cool

[alecton]

Are there any holograms that can be projected on air? outside the film? Kinda like star wars... sorry if I sound stupid, but ya never know.

[deanrdavis]

No, it always requires a transparent surface. The only exception would be some kind of fog to receive projected images from different directions. Star Wars is fiction. You did know that... right?

[AshMashMash]

Good old How its Made!

[Blugrazz]

You can make simple holographic pictures at home, but you have to use the laser to view it as well as make it. You can get a helium-neon laser, some lenses and other optics, some film, and build your own table for a few hundred.

[BlooDHunTeR352]

The show is "How Its Made" (Like DAGman27 said) and anyway, this isnt fake. Saw it on the discovery channel so.... And zwanphony, how can u use Photoshop to make a whole part of a show?

[Muscar]

Ehhm, no it´s not fake, i have one of there holograms, it´s a smal dragin on a round film, and it´s just like in the video, tha object´s don stick out, it looks like they are behind the film.

[soakland2]

Morons! You wouldn't know fake if it bit you in the ass. Do some research before opening your mouth.

[eatwasabi]

Learn to take a joke

[zwanphony]

...and not be such a "moron"

[zwanphony]

even the guy speaking looks fake. i dunno, i'm going with my instinct on this one...FAKE.

[deanrdavis]

Sorry, you lose on this one. It's real. You may want to check your local library before calling something fake.

[zwanphony]

clearly a FAKE.

prolly a photoshopped video.

[un4got10]

Ever saw a hologram sticker? AMD.. IBM?

[kopaka649]

...holograms were invented over 50 years ago

[gogglebox69]

Tottally fake... I can't believe people think tis is real

[deanrdavis]

Have you ever actually opened a book?

[deanrdavis]

You didn't get much education... did you? Do you get out of the house much? You can buy these in novelty shops. Clearly an idiot.

[DAGman27]

This isn't FAKE. It's "How it's Made" and thats not David Schwimmer :|, it's Mark Tewksbury, some former Canadian Olympic swimmer (I think). Why he was chosen to host this show I'll never know.

[conekt]

Is that David Schwimmer?

[BernieDK]

its discovery who had put the music on so cant remove it whitout removing some of the voice

[Syd1940]

Interesting and 'illuminating' :o), but it would be improved greatly if you cut out the dreadful music

[siddacious]

HAH! "illuminating"! You should go into comedy. Seriously. Best joke ever.

[bentonetc]

Seriously man, how do you come up with this?
