- Holograms are an amazing trick of physics that allow you to encode 3d information into a 2d film, and today we explore how to make them the easy way. This isn't some silly trick with a cell phone and acrylic, this is the real deal.

Should probably pin the link 😅 Love your vids! Been watching for awhile, ever since you uploaded your magnet implant video! After awhile I ended up getting some nfc & rfid chips implanted in my hand 🤣
I want a new video lol
when’s the next video
thethoughtemporiun As a ben 10 fan i have to ask would this technolgy work inside a wrist watch like device ???
We designed a class around holograms in high school in the 80s. Back then, we were required to build a vibration free table, low pressure inner tubes, sand table the size of a pool table, turn off the HVAC, let it stabilize for a few minutes, then expose onto Kodak plates. Then take the plates and develop like film. These created regular light visible holograms and we really enjoyed the process and the science, and really blew minds by cutting the plates in 1/2 giving us two holograms, instead of two halves of a hologram. I wish I still had the one we made, had a bunch of D&D dice and some other trinkets in it. Are you saying these don't require chemical processing?!? I'll have to see the full video and find out!
Oh wow
That's cool as fuck. I wonder, if someday we can make it into something that can be used for 3D presentations
Sounds like the coolest class ever
Damn. All we did were worksheets
Very interesting. From their website:
making holograms was not always this easy
Usually, after creating your hologram with the laser, you still had one of the hardest parts ahead of you: the developing. For years and years, holograms have typically been made on silver-halide emulsion film, very much like a higher resolution version of the film in traditional cameras. Developing these holograms involved a complex process of several different chemical baths, all in the dark, of course. Before that, some holograms were made on DCG, or Dichromate Gelatin, the development for which included dipping the holograms into boiling alcohol
I loved when you took away the object, but the hologram version remained
that was such a cool shot
Holograms are so cool. They're a passive light field display
It's nice that I found this vid. while beeing nearly at the end of writing my Masterthesis about Hologramms 😆
What if my table isn't heavy enough? 🤔
I made one of these in uni way back when, and they're super cool! What's neat is you can still see the entire object even if you cut off a piece of the hologram, just not from all angles anymore.
What .. thats sick..
Maybe the film just forgot the castle was removed from behind.
Holograms are so cool!!! I wish they were a bigger part of everyday life!
Make it so
@@pacotaco1246preach
It's as if the object is gone but it's soul stayed
the most underrated technology ever
That might just be one of the coolest things I've ever seen.
Star Wars has begun
love how he says "all you need" and then lists a laser like everyone conveniently has one lmao
Holograms seems to me ghost images
Bruno: *OH SHIT THEY FOUND OUT*
all the new shorts content is fantastic!
Perhaps there is a way to make the process not analog... Imagine a camera capable of digitally capturing the information of an object, and then recording the hologram on a plate as many times as necessary... You could even make 3D computer-generated holograms.
This is so cool!
When are we getting hologram hardware on our phones?
That’s would be awesome with halo Lego
someone needs to make joi irl
That hologram so ez to make like my skin after sleeping
Would be neat to see one made with a supercontinuum laser.
> _"supercontinuum laser"_
whats that?
@@yash1152 A continuous spectrum light source, coherent but not an actual laser. This wouldn't produce interference pattern, I think.
I wish I had the brain capacity to comprehend the science behind this stuff. But alas, I'm of average intelligence instead lol
ah, so all I need is a laser and some fancy plate
Proof that infrared technology can copy a whole reality, objects and realms
Soo, if you had a butt ton of those and made a machine to pass them over a light source to work like a projector you could make truly 3-d movies
make the chocolate frog from hogwarts
“super easy”
Very cool, didnt know how they are made
Looks like timelord art from doctor who.
Looks like a 90's CGI model.
Also hollow grams:FAN AT ALOT OF SPEED
can you do a human sized one?
Commenting so I can find this later
Bruno cosplayers are gonna have a field day
Just saw that you're closing in on a million subs.... Guess I'll stop lurking and finally subscribe
loving itttt!
That is really cool, also is that the Metal Earth Notre Dame model?
Okay, now all we need to do is make the lazar responsive, movable, and have sound come from it. Then Star Wars is even closer to being real!
This is magic
@the thought emporium....
Do you think it would be possible to make holographic lipstick. Like how they make holographic chocolate?
was that a Mach-Zehnder interferometer I saw?
That’s weirdly satisfying, I once was using my brothers washroom, in there, was a picture of Jesus Christ, on the wall, but it was a hologram, so one angle was him awake crucified and the other was him passed, but the angle I saw, was the two of them in one and it made me ask my brother why there was a picture of Forrest Whittaker on his wall!
Cut it in half and show us how it had a double image
It's magic!
Smarties taste better than M&Ms
Smarties taste like nothing
A true hologram is a medium-less display, so as soon as you include projecting light onto anything, like a block/pyramid of glass or sheet of film, its no longer a hologram
Good
thats so fucking cool man
I thought you had to split the laser?
Okay, I'm in the dark room but what are all those other people doing here?
What type of lazer?
How do I make a hologram image of Einstein to project onto a screen?
That's not a hologram, but rather a holograph. A hologram floats in the air. A holograph is on film or another surface.
This is "simple" now.
But the science behind it is brilliant.
Then not to forget that some genius had to think this thing up!
Much of the time, new tech is discovered by shear accident. Or need, necessity.
what kinda plate is that? is that same with film roll?
Does it have to be coherent laser light or would a normal torch work. How about an LEP (laser excited phosphor) torch... to get a white colour image?
It’s bigger on the inside
Shroud of Turin
Is there a way to make it double sided?
Can you that with pictures
Wow
How do you even do this, next your going to make a living creature out of chemicals.
"all you need is a dark room"
Life is strange fans getting ptsd triggered
What about Video Holograms or touch pads?
4D Holograms, i think?
Homemade holographic glass or it doesn't count
It would be amazing to make holograms that are 1 meter by 1 meter or bigger. You would need a far bigger and far more powerful laser, but that would be a one time investment. What makes such big holograms inhibitingly expensive, apart from such large holographic plates just not being sold AFAIK, is the high price of holographic plates.
The holographic plates sold on Litiholo are very small and already very expensive. Shame. Making holograms would only really become interresting as a way to make graphic art if you could record 1m by 1m or bigger holograms.
Imagine a 1m wide and 2m tall hologram of a statue or a person. Or a 2m wide and 1,5m tall hologram of a miniature city with some mountains in the background. At that size holograms would become interresting for graphic artists to use in making graphic art.
If only it could be offered at a much cheaper price.
Then large holograms could become a real artform.
*is
😮
👍🏻
so simple getting what i need to do this you know the 20000$ laser and everything
Make Tupac
Huh
so this how vtuber works?
can you not just turn the beam off
If you're using a non-pulsed laser, then you want it on for a bit to stabilize the emissions. Typically, a shutter connected to a timer would be used. Lasers are much more powerful and available than when I made holograms at the end of the 1980s. I used a 6mW HeNe laser back then and had some long exposure times. Longer exposure times were more sensitive to vibrations so I to use a big and heavy sandbox.
Real holograms would be particle locks you can do with optical tweezers. This isn't a true hologram since you need a film for the image to appear. With particle locks you can make particles move and shine in the air as a physical entity
Nope, as it would have mass to it, the prefix holo would indicate that it has no mass
You don't have to develop it!! I took holographic in school 🫠
