The awesome thing is that, one day, we may be able to use holograms to store data in place of traditional motherboards, USB, and magnetic storage devices. Imagine the computing revolution when your hard-drive is made up of light, and can readily change forms to suit different tasks! The future will be glorious :D
This works because there is basically an entire two dimensional image at every point on the film, so when you look at the film, you see one "bit" of every 2D image on the film. The moment you move your head to a different place, you see a different set of 2D images, resulting in an actual 3D image, since the image changes depending on which angle you look at it. I did this in my physics class, except with a red laser, not a green one. It's much more entertaining to see it for yourself.
True, this is called LZP Holography, where the local coherence is used. One can either split off a part of the main beam w/ a semi mirror plate, and redirect it, or shoot your hologram in a reflective holography mode, where part of the beam travels thru the recording material plane, hits the object and reflects back. I've made zone plates which act as segmented prisms, splitting off light mid travel, and redirecting it towards the centroid, or about the object, to get better object coverage.
There's a mistake in the developing section. The second bath is the "Stop Bath". It stops the developer from making the film too dark. Then it's rinsed. Then the "Bleach" is what turns the film clear by removing the silver molecules. You can see it work in the third bath, not the second. Very well done, otherwise!
@mikejamesbelanger Most of the weight of a holographic table is in the pedestal, which is usually some kind of concrete structure. The steel table tops are usually coupled to those 'blocks'. I use active damping to do so. The really good holograms are not so simple, they take translations between various formats of media, and usually robotic gear to physical move the set ups around... otherwise they are just 'still lifes', simple portraits of something, or one.
i just watch holographic concert of hatsune miku on youtube and im so amazed by it. i really wonder how hologram can project such a cool 3D graphic. so i search for a video that explain how the hologram works. and i found this video. after watching this, a strange thought just enter my mind that telling me hologram is a science fiction. it does not exist at all. thanks to this inspirational video
Some of those guys in the last holo looked like holographers I knew from the mid 80s. I don't think most people believe the kinds of stuff that went on at their place at that old mill so close to the tressles they had to wait till the trolleys stopped running before they could expose the plates, well after midnight till early morning. Those dudes seriously rocked! They even had 3 holograms hanging in the Philadelphia Museum Of Art... for about 15 minutes-until the security guards caught them!
and that's why after almost 50 years they are still really expensive. but it's way more easy to understand if you just go to wikipedia and look at the pictures. this way you can see which way the laser is going.
A hologram is a recording of the interference pattern between 2 beams (waves) of coherent liught (regular repitious waves). When the reference light is reproduced, the object light is recreated through diffraction and interference, with both brightness and direction. Wiki diffraction.
It's not a 3d illusion, it's really there. The depth is just 'encoded' or 'captured' in the thickness of the film. Or that's what I understood from the videos that tested and physics girl made on the subject.
@GamingBlitzDOTcom Actually, now that you mention it, go google "volumetric display". It's exactly what you mean, display based on this principle, except with different frames, which are able to display motion.
@trmdtv People used to be able to buy 'holographic film' at neighborhood photo supply stores which sold standard cameras and chemicals. Both Kodak and Agfa made it, and it was available on glass plates or as film in various sizes. NOW... they stopped production so you either have to find a supplier of exotic and expensive European or Russian films/plates and import it (or find a U.S. wholesaler). OR, like I do... you can make your own emulsions and mix your own developers, etc.
i hate typing with phones...my comment continued: it turns out it was caused by the sunlight reflecting off the concave window on the washing machine. you could actualy walk nearly 360 degree around this floating light! thats what brought me here anyways.
Lots of errors, but a very obvious one is what in the video is called 'bleach' was actually the 'fixer', while that solution that turned the pelloid 'transparent', that, was the 'bleach'. Interestingly, they show a hologram as a result of this which is in COLOR, and that can not be done with a single color laser, unless each color image is a done separately with angular compensations for each color, that process is very intensive and is called, 'pseudo-color holography'. This is monochromatic!
The first time I tried making a hologram, I forgot to take off the collimating lens, so I get a little dot when I developed it, woops. The second time I tried making a hologram, the picture never showed up. At all. It was a transmission hologram, on a vibration isolation table at my school, (it wasn't the vibration)... I'm not sure what I did wrong, but holographic film is expensive!
Except that the Tupac performance was an optical illusion called Peppers Ghost Illusion, not a hologram. The core concept behind the illusion has been around for a few hundred years. It is different (and a lot more simple) than a true hologram. I didn't know the difference either, just found out about it my self.
The hologram version of Tupac also cares for science. He's gone rogue, you see, and he's created holographic Elvis and Bach to join him. They attack at noon tomorrow. May the power of rock, rap and classical be with us all.
@LaidbackPlayboy Yeah for the sake of time, the "how its made" show really rushes through very complicated topics and most of the time skips subtle information to understand whats going on.
yup cuz of tupac! See, for a change of events, RAP has made people seek knowledge and thus creating a positive effect on society! Suck on that people who say rap causes nothing but negativity.
omg.. so the japanese are thinking about how to commercialise touchable 3d hologram.. discovery channel goes on and explain how little hologram stickers are made...?

I love how no matter how technologically advanced we get, the music in documentaries will always be tuned into the late 70's early 80's.
damn, this reminds me of the early days of photography , 50 yrs everyone will have a hologramice camera that you can later project in your home ...

This IS the way you can make a hologram .I think its title fits perfectly well.
seriously the most important comment on TH-cam ever.. No. The internet. Thank you sir/mamn.

I can't believe how far we have come in only a few years with this tech

Very cool. Thanks for sharing this.
wow i didn't know holograms could be animated! neat-o!
I was really interested in this. Now I see the hard work put into creating Miku Hatsune's concerts
why havent they started making holograms for Yu-Gi-Oh yet??? Its making me want to go to school and learn and build one my self, wish me luck people
results?
sic tune , captn beefheart meets aphex twin
Highly underrated comment
"12ns: an infinitely short period of time"...
Ouch!
you can actually get kits to make holograms, you know how cool that'd be? it'd be like "Yea, heres my couch, my tv, oh, and my hologram" XP
Cool. Thanks for sharing.
how the music is so bad i cant even get past the first 10seconds
@ricjones1994 sorry to say, but the Miku concert was actually a 2d projection on a pane of glass... I was disappointed too...
@GamingBlitzDOTcom Actually, now that you mention it, go google "volumetric display". It's exactly what you mean, display based on this principle, except with different frames, which are able to display motion.
i whould love to have a picture of the one i love that way...

there are some vids on youtube showing how to make your own holograms with cd cases...
If you mean in the beginning than i think he is just using it as a pointer.... but... I don't really know...
I want to make a hologram of a couple of muscular body guards at the front of my house to prevent thieves from breaking in.
hey how can you explain tupac's hologram?? I thought someone should be there to record the performance first, then recreate it.
@HafwayHolmes
And when they are then combined, im lost again!
so each one of those little tazo disks i collected as a kid took 1 hour to make?
i hate typing with phones...my comment continued: it turns out it was caused by the sunlight reflecting off the concave window on the washing machine. you could actualy walk nearly 360 degree around this floating light! thats what brought me here anyways.
haha i love butters! yeah i gotta catch up on my southpark episodes, havent seen them in a while...
@GamingBlitzDOTcom u seen the 3DS?

The Easiest hologram to do is the Pepper's Ghost which is also an illusion
@Abolisher45 step 1: make sure there's no vibrations by getting gigantic amounts of steel.
step 2: make a hologram.
Coachella got me watching such stuff
really cool
Bare hands in the stop bath and darkroom chemicals is a big no no!
I would call this a holograph.
Is it expensive to make?
I can die in peace now.
the gorrialz did a hollogram at one of their concerts i think it was madonna for one of their songs... it was beast
thank you!! people should really start using the correct form of your and you're.
also many people say alot, but its 2 words: a lot
The first time I tried making a hologram, I forgot to take off the collimating lens, so I get a little dot when I developed it, woops. The second time I tried making a hologram, the picture never showed up. At all. It was a transmission hologram, on a vibration isolation table at my school, (it wasn't the vibration)... I'm not sure what I did wrong, but holographic film is expensive!
so how is it made again??
30 PEOPLE ARE SARAH CONNER

it be cool there was a cam taht turn what it records to Holograms that'd be so cool
@LaidbackPlayboy Yeah for the sake of time, the "how its made" show really rushes through very complicated topics and most of the time skips subtle information to understand whats going on.
That Miku concert musta taken forever! 0 _0
Not only was the developmet section incorrect as pointed below, but how did they get a color hologram from just a green laser? Not possible.
It'll blow your mind: The film material is just black an white. 😂
Still do not know how is made the metallic 2D hologram sticker....
Ah the good ol' days...when disovery actually showed smart interesting things...
there used to be "the museum of holography" in nyc back in 1972 -- very cool -- i own several holograms....all are amazing.
yup cuz of tupac! See, for a change of events, RAP has made people seek knowledge and thus creating a positive effect on society! Suck on that people who say rap causes nothing but negativity.
very impressive
That's not a Hologram!!!! That's a fancy picture!!!!
@GamingBlitzDOTcom Sure just be don't try to move the 2 ton steel by yourself.
omg.. so the japanese are thinking about how to commercialise touchable 3d hologram.. discovery channel goes on and explain how little hologram stickers are made...?
AWESOME!!! But is really hard to understand.
Reading invisible landscapes by Terence McKenna brought me here.
how long will it take to produce a holographic version of cod
woah cool
Well based on the appearance of your comment, it wasn't refering to one person, it was a question for anyone to answer.
i miss having the science channel
:'(
My desire to make counterfeits brought me here
Good shit.
@Hafwayholmes I understood more from your short comment than from the video :-) Thanx
if less is more, just think how much more more is
@GamingBlitzDOTcom the 3ds will have no glasses
How could you discover it if you already knew it? (ain't English great with all it's homonyms?)
Thanks so much...
you mean "it's", a contraction of "it is." "its" is a possessive.
i really dont get what the point of the paper is.
Will.i.am's next single being played as the background music
I stool don't get how a flat piece of film can have a 3d image in it.
Pretty sure I just seen Pac in that hologram too!!!
"12 Nano seconds, an infinitely short period of time." that's a bunch of BS
Lol, if you press mute, you can't hear the man talking. But I guess you can't hear him anyway...
So.... they used wizardry to make it. Got it!
lol... captions at 2:22 " this however i think film is the tax code close with the he's okay"
@GamingBlitzDOTcom kinda like the 3DS
Cool
haha my bad..
you got me there..
hideto matsumoto brought me here.
True, the music doesn't match the video. Maybe a slightly soft techno would of been better.
The Tupac hologram wasn't high tech (nor was it an actual "hologram") The actual CG animation was extremely impressive though.
Alright, I think I get it.
How to make a hologram:
Step 1: Make a hologram.
i go to sleep with this show on Sc Channel
That awkward moment when both the top comments are the same.
03:50 GLOVES! :@!!!!!!
anyone know how to made hand drawn holograms?
