Holograms are photographic recordings of 3D scenes. Unlike a camera, which captures one view through a small viewer focused by a lens, holograms capture an entire light field which allows them to recreate the 3D scene. Shimmery 2D projections, like pre-recorded Pepper’s ghost illusion, are often confused with 3D holograms.

It is a very good introduction to the topic, though of course, a much longer video would be required to fully explain how the diffraction properties of waves ends up producing a 3D image that rotates in the correct way when we change angle we look at it from.

First i's a nice prisetation thanks. To understand how we can see the entire image/picture in bouth in the entire hologram as-well as in eahc fragment of the hologram we must undrestant that a hologram is not a picture but an Optical phenominan/media and in this case work's like a window. Lets say if we cover at entire window whit a black sheet of paper with a hole in somewhere and if we take a look through this hole no matter where it is plased, we'll find that we'll see the whole room/landscape/image only our veawing angle is slithly deferint depending where the hole is plased in the paper, again as we remove the entire paper we'll naturaly still see the entire room/landscape/image. Erros: Erro in this prisentation: be aveair its chrutioul that both the reference and objeckt beam is coherent to make a inteferince pattern/hologram. Coretion: The deference is not about coherentce but the vawe-front/vawe-pattern. the referance wave pattern is regular where the opject pattern is destorted/formed by the shape of the opject theo still coherent whit the reference beam/pattern when they mede and form the inteference pattern on the film and are recorted. Thats why we carefuly messoure the lenghts of all our optical rails/trains when recort a hologram. Spelling Erros: Pardon my many lag of propper english spelling skills :-)

As a kid in the 80's I always wondered how the holograms for stickers like Lisa Frank and on toy lines like the Visionaries & Supernaturals were created, they appeared to be sculptures photographed in 3D. Thank you for a brief look into the creation of those images and if you don't know about the figures I am referring to, check them out, esp. the Visionaries line, some amazingly articulated 1980's nostalgia right there !!!

Because so many people think they are holograms, I always refer to peppers ghost as "holograms" with full air quotes.

I want to minor in physics and I think I could do a lot of research there.

This always puzzled me, but now I know, so thanks.

Thank you so much for stating the fact that for holograms like this; for each division of the whole, that the whole is contained within each division. This fact is one of the rarest things demonstrable, about some very special things, such as a single member of a species still has all the information about that species. Or a single instance of an electron, still has all the properties of all electrons. Possibly there is such a relationship with many other intangible relationships that may or do exist all through the universe....and teaching about things like this really does inspire one to wonder about all the other types which exist in this, or similar beautiful ways. Thank you much! Thank you for sharing this, with us!

Because the interference pattern on the holographic film spreads out the information on it with no correspondence to space. In other terms, if you take a single ray of light, its "presence" will alter the whole interference pattern, therefore each single piece of holographic film holds information about all the light rays reflected by the object.

How cool that you can cut a holographic film apart and still see the whole object. Like what a cool idea for a family gathering- take a big hologram, show it off, and cut it into as many pieces as there are people in front of everyone. You'd have to pass them out and tell everyone to look closely before they'd get it.
