Learn How to Make a Hologram: Step-by-Step Guide & Equations

[ghost313]

Can anyone tell me,or send me a link to a paper on holograms,how to make them and if possible their equations?

Scratch holograms.

I never did get around to making one of these.

Did you know you can hand-make crude holograms by manually cutting interference fringes into plastic or metal?

Ha. beat me to it

Thank you all for your kind answears :)

It is an awful lot harder to produce a holographic image of an actual object. You need a good light source, a very stable stage with good mirrors and also a good, flat photographic plate. The early years of optical holography involved a lot of learning about improving techniques. It's almost a 'turn the handle' job now.

We used this kit in our undergraduate optics lab:

and it works great- no problems.

That is impressive. Someone else has done all the hard work and technology, then. Would you really say that it's a trivial problem to do it - starting from scratch? I guess you will remember how limited the early holograms were. Is the solid state laser less susceptible to vibrations than the gas lasers they used way back? In the video they keep mentioning vibrations. What precautions do you take in the lab, to ensure good images? IS it really as straightforward as the advertising video claims?
The developer free film makes life a lot easier, of course.

It really is as simple as the advertising claims- no need for heavy stabilized tables, etc. Each student group's initial hologram was suboptimal, but every group produced good-quality holograms using a variety of objects- one group even recorded multiple holograms on a single plate to demonstrate the principle of holographic memory.

I made a hologram of a computer chip:

I remember that, in the past, there were serious problems in producing decent holograms and an expensive setup was required. Do you know what changed?

Nope. Smarter engineers?
