- Hi John...Hope I can help out in your quest for laser show info.
- There is a company out there named Pangolin, which develops laser scanning
- software for the Amiga computer. The computer drives devices known as
- Galvometers (small motor type devices built in the fashion of an Analog meter
- movement). To the shafts of these galvometers are mounted small mirrors. The
- galvo/mirror units are mounted 90 deg apart from one another to effect a x/y
- scan.
- Most of the systems I've seen use lasers, altho collimated light sources
- could be an option, I'd imagine. The lasers used are normally of the Argon or
- Krypton ion type...with Krypton being the favorite, in that it can produce a
- wider range of color over the Argon
- The address for Pangolin is:
- Pangolin Laser Software
- 933 N Kenmore Street, Suite 317-A
- Arlington Virginia 22201
- (703 527-4880
-
- Also, If you "tinker" a great book on the subject is:
- The Laser Cookbook, by Gordon McComb Tab Books, 1988
-
- McComb walks you thru 88 laser related projects with a couple fine chapters on
- Light Show generation and the use of Galvos.
- Hope that helps....
