Holograms at MIT Museum

2 holograms at the MIT Museum - one of a telescope, the other of a magnifying glass.

The holograms in the exhibit were apparently made by Greg Cherry/Cherry Optical Holography

I want one on my wall! They need to mass produce these.

@skimberk1 Once you know how to make a hologram, all you have to do is make a hologram of a telescope. Really! Any surface that is both struck by the object beam and line-of-sight from the film will show up in the hologram. This includes any and all optical effects, such as mirrors and lenses.

For this type of hologram, you need to shine laser light of the same wavelength and at the same angle as the light used to create the hologram at it in order to view it.

Yes, the holograms are contained within a 2D space (and yes, our brain interprets them as being truely 3D). But if the laser isn't shining at the hologram at just the right angle, you can't see it.

There are of course other types of holograms that can be seen in reflected white light. Those you could hang on your wall.

I WANT TO BELIEVE THEY ARE JUST WINDOWS

but then you could take the holograms off the wall and show that they are FRAMED

Really amazing, any more???

Word. Split a laser in two, diffract one beam so it can reflect off the entire surface area of the telescope and contact the film. Diffract the other beam so that it contacts the entire film like the first beam. They should imprint the film simultaneously creating an interference pattern. Then when you shine light of the same original frequency, bam you've got a 3-dimensional window to a telescope.

The first hologram is icredible the second one isn't as good but is still great. Does anyone now how to make the first one?

WOW!
