history of holograms

Hi everyone,

I’m working on a school project on holography and I’m struggling to find anything on the history of holograms. Does anyone know anything on the subject? Please help!

Google... and this wiki is a good place to start:
www.holowiki.org...

Check the links at the bottom. A very detailed history is here:

Here's a hologram Tutorial.

Man, I wish the internet was around when I
was in school...

Ow! Ok, saradowson, Lexion is usually pretty accurate but this link is an example to what a hologram is NOT.

A hologram involves reconstruction of an image from a record of interference fringes produced by a source of coherent light, typically a laser.

What a hologram ISN'T, is anything you saw on Star Wars, Star Trek or, as in the case of this link, anything whatsoever that an art or marketing department thinks a hologram is. In this example, some "artsy" guy is conflating chromakeying/green/blue screen techniques with holograms. Because to an artsy sort of person, any, ANY unusual visual effect is a "hologram". Thus do you get advertising wonks calling any transparent flat screen, fog projector, Pepper's Ghost or 3D image a "hologram". Typically they are not.

This may prove difficult to sort out, as many marketing dweebs seriously DO NOT KNOW what a hologram is, and thus present very sincere claims. As an example, Musion's marketing department seem convinced that they actually sell a holographic display, when in truth it's nothing more than some transparent projection film and a Pepper's Ghost trick. This, unfortunately, seems mainly to be due to George Lucas calling that effect in Star Wars a "hologram", when in fact he had no clue what one was, past something he saw at Disneyland on the Haunted Mansion ride.

So now, you have idiots who think if you can walk behind a piece of Saran Wrap that has an image on it thrown by a projector you can pick up at Office Depot, that qualifies your effect system to be a hologram.

I started a thread on the subject a while back. It did not get very many hits or much interest???? but you may get some good info out of it or perhaps some links. Have fun with your project, sounds like a good one! Antar

It's a hot point of mine. I don't know why, really. Well, it's true I'd like to set most marketing guys on fire with a bucket of gasoline, and this topic is just another lit match along the way.

Somewhere in Hell, there is a special bolgia filled with the people that absconded perfectly good terms for their own uses. In there will be the namer of the so-called P.A.T.R.I.O.T. act, the lefty that first conflated "progressive" (meaning graduated or incremented) taxes with the concept that they were "progressive" in a social sense, and the marketing people that grab any physics term that sounds good, like "quantum", "laser" or "hologram", thus permanently confusing generations to come.

Hello,

I’ve found this site useful when I was doing a similar sounding project on holography. www.ihma.org...
A history of commercial holography is displayed in chronological order. When I was searching the Internet I came across this You Tube hologram video on how holograms are made…you can use it as well to make your project more interesting.
youtube.com...

Hope that helps.

Good luck
