Transmission Hologram With Reference Beam
Experimenter: Chris Cleven
This is a trial setup for a transmission hologram with a reference beam. The light strikes the object from two directions. We modeled after a procedure developed by Dan Wright.
The holographic image below, with a die and a small plastic skull, was taken with an exposure time of about 40 seconds, whereas we had calculated 20 as the exposure which would give optimum density on the film.
A discussion with Clay Turner brought the following comments about the procedure:
