Three transmission holograms (video)

[FloggedSynapse]

I'm addicted to making these holograms now! It's not difficult.

Here's a picture of my hologram exposure area:


Everything rests on a board with bubblewrap under it. I've propped my brick laser pointer on the pot and the uncollimated output illuminates the hologram microcosm. For these transmission holograms the objects being holo'd rest in front of the hologram glass emulsion. Once the film is exposed one shines an unfocused laser at the film to recreate the object. That's it.

The third video below is the hologram created as seen in above picture. There's 7 inches of depth.

Less than $50.00 is all that's required to purchase film and developer. (integraf.com)

These videos do not convey the beauty of the actual hologram!

And thus it begins... Welcome to the addicts club

It's not difficult

Nobody ever said it was , but the problem with holography is that you always want more, you always strive for the perfect hologram. Holographers are their own worse critics as i'm sure you'll find out as you progress.

These videos do not convey the beauty of the actual hologram!

Sadly, video's never do, but at least it givs us an idea of what you're doing and is definately better than a still photograph. It still looks as though you've got some horizontal banding, did you 'paint' the edge of the plates before exposure as I suggested?

Anyway, that's awsome work, keep it up

Thank you for the compliments!

I did not blacken the top of the glass. Seemed one more thing to be bothered with while in the dark, and I was a little worried the marker chemicals would affect the development.

I'm not certain what is causing the banding, though the effect is not entirely undesirable.. at least in the videos it gives the holograms a 'TV' look. It may be my apparatus is constraining the vibrations such, how the film is produced, or total internal reflection (as you suggested)

Next time I will blacken the top of the glass and see if that reduces banding. Living in a high-hrise - very difficult to attain a vibration free area.

Excellent!!! The importance of vibration damping is waaaaay overrated. You probably don't need the bubblewrap under your base. The lines seen in the video might just be caused by light hitting the edge of the plate during reconstruction. Cover the edge and see how it looks. Again, great work.
