The real way to make Holograms

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.

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!

I loved when you took away the object, but the hologram version remained
that was such a cool shot

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.

Holograms are so cool. They're a passive light field display

[SarahNova]

Holograms are so cool!!! I wish they were a bigger part of everyday life!

It's nice that I found this vid. while beeing nearly at the end of writing my Masterthesis about Hologramms 😆

Maybe the film just forgot the castle was removed from behind.

That might just be one of the coolest things I've ever seen.

It's as if the object is gone but it's soul stayed

[zenith]

all the new shorts content is fantastic!

[asap._.drt]

love how he says "all you need" and then lists a laser like everyone conveniently has one lmao

[Artilect]

Proof that infrared technology can copy a whole reality, objects and realms

[Subspace_Tripmine]

That hologram so ez to make like my skin after sleeping

[riddixdan]

ah, so all I need is a laser and some fancy plate

[pazyguerra]

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.

Very cool, didnt know how they are made

[ryanhebron]

Would be neat to see one made with a supercontinuum laser.

[brimmybri]

That’s would be awesome with halo Lego

[Mysenhoffle]

Bruno cosplayers are gonna have a field day

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!
