Nice

what is the hologram of?

Another magnificent transmission hologram. Here we have some glass and other organic forms


Hologram of some blooms on my Christmas cactus!

These are live blooms, still attached to the plant. I placed cactus next to the hologram staging area. A couple of blooms then drooped in front of the laser for this transmission hologram. Exposure was about 1 second using a 75mW laser diode from a DVD burner. Integraf PFG-01 holographic emulsion was used.



I had difficulty videoing this soft and delicate hologram. Looks much better live.

Here's a photo of the blooming plant, same flowers shown in above hologram -

With technology like this being around since the dawn of laser itself, some 50 years ago, you'd think the concept of a 2D picture itself would be obsolete by now.

That's seriously impressive.

I want it.

What other holograms you guys have?

For the transmission holograms are you using the single beam approach, or splitting the beam into reference and object?

Some years ago I used to make transmissions with my HeNe, but lost interest because I wasn't aware of the integraph films. Kodak S0-173 did the trick, but the holograms were dim because the emulsion wasn't thick enough.

Single beam approach. Very simple, most of the work is the 8-10 minutes of film development after the ~1 second exposure.

Here's a picture of my hologram staging area -

The laser is without a lens, as you can see. Bubblewrap helps with vibrations. Considering I'm on the 6th floor of a 16 floor building vibrations are a big problem.

The laser is a DIY, using a Sony DVD diode, ~75mW. LM317 regulator circuit. The laser is left on for 1-2 hours, during which time 6-9 holograms can be created.

Not difficult to do, though the film development is tedious.

Another look at my hologram collection -



Two holograms below were exposed yesterday. Not bad.

More holograms. Here's my modded keychain hologram viewer - ~15mW 635nm

That's really cool! Makes me wonder why I never thought about doing this.. Thanks for sharing this.
