If making Denisyuk type holograms, it will work fine. If making "split beam" holograms, mount it to something not connected to the table used for the recording system to avoid vibration caused by it.

Looks like your laser has a low coherence length. I would suggest trying a laser with a single longitudinal mode.

No math is needed here, and no description of how a spatial filter works was requested. I'd recommend you look at Ed Wesly's pages or contact him for replacement pinholes for that spatial filter. He has many of them and quite a few spare parts. You can also ask the question of the Facebook holograph...

I built x-cube light engines for a few years and even assembled one out of custom dichroic mirrors. The problem you may face is that for those harvested from projectors, there are often wavelength dependent wave plates attached (or special coatings) that can mess with the polarization of the individ...

Would a heavy flat piece of wood work? For Denisyuk? Yes. I'd use any room except the server room. Too much noise, wind, and vibration. Also, skip the fabric base. Mounting is better than pinching the film. Try heavy metal parts instead of books for weights. Concentrate on three-point stability bet...

Anyone reading the garbage on this thread is welcome to visit the holography pages on Facebook where such discussions happen all the time but without the disruptive drama caused by this disgusting troll, who has been banned from them both for the behavior shown here. There you'll find many experienc...

By the way, about this figure of 440 ????????????????? Stick it in your ass. By the way, what about Hariharan's statement on the page you posted that says thin materials are Q=<<1? Not 10. And let's not forget how reconstruction depends on polarization! If you ever made a hologram instead of depend...

Just pathetic.

This is the reason nobody posts here anymore. Certainly why I don't.

The factor of 2π would take Q ~42., but I usually leave out the 2π, since the criterion is not accurate, as Hariharan pointed out. Other criteria leave out the 2π. However, Q ~ 7, puts us in the Raman Nath regime. So you quote an equation, then after an obvious error is pointed out, you backpedal b...

Your answer doesn't pass the smell test. There's no way with visible light that a 16 micron volume material is "thin".

Transmission holograms can be thick or thin.

Fresnel reflection isn't restricted to reflection off a Fresnel lens.

Dispersion happens despite Bragg selectivity.
