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.
