I am interested in finding out more information about laser XY beam
positioning systems. Specifcally, such systems that Laser Rock and
such use at your local planetarium/science museum. I know that
typically they use high speed galvanometers driven with feedback
controlled type servo amplifiers which in turn are driven by a
microprocessor or other control system. Are there other more
solid state methods of positioning? How about intensity (Z axis)
control?
Are there any people out there who have technical experience with
these systems? I am very interested in communicating with you if
you do. I want to attempt to build such a system and need your
assistance to get ideas on how to implement it. If there are any
books on this subject I would like to know of them also.
Thanks,
Phil Biehl
