RE: ATM "Frozen" liquid mirrors

[Murray Foster <murray@vitalimages.com>]

First, thanks Peter for the overview.

Bearings: How about using a liquid bearing, ie float the container in water
and us a magnetic coupling not directly attached to the containers to turn
the one that is floating.

Environment: A lot of attention is focused on creating vibration free
environments when capturing holograms. There is a book that I have at home
about do-it-yourself holograms. I think its called the "Hologram Making
Handbook" (I'll get the correct title to you in the future). The basic
method is to build a big sandbox and support it on partially inflated inner
tubes (the small trailer sized ones). Sand is used because it provides a
medium for positioning mirrors, lenses and film holders. For our purposes a
good sized chunk of concrete would create a nice source of inertia for a
stable platform that would dampen vibrations.
