[sci.physics] Laser Deflection & Modulation

milo@ndmath.UUCP (06/19/87)

Would anyone out there happen to know of someplace where I could get
some relatively inexpensive laser beam deflection hardware of the type used
to create laser light shows?

I don't need anything amazingly fast, just something that can be interfaced
to a computer which can sweep the beam through about 30 degrees in the X
and Y directions.  I'm also looking for some kind of electronic shutter device
that could be used to turn the beam on and off.

The application is a simple laser light-show device for experimental purposes
The equipment will probably be used with a low power helium neon laser.
The beam doesn't have to move super-fast...but it needs to move at least
fast enough to draw several words and retrace them frequently enough to
avoid major flicker.
