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 -
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.
