http://www.gs-scanners.com/ This link takes you to the General Scanning home page. General Scanning is a major manufacturer of precision galvanometer scanners. In our project, we used the GS 100 and GS 120 units. They worked well. You can find them on the surplus market, but be careful in purchasing. The units are easily damaged.
http://www.cambridgetechnology.com/index.html Cambridge Technology is another major manufacturer of precision galvanometer scanners. Their scanners are very fast and remarkably precise.

Lawrence, J.D. A Catalog of Special Plane Curves. New York: Dover, 1972.... a classic book on plane curves.

MVM Electronics Inc is a company that makes high quality optical control products for laser projection devices. The PCAOM unit in this project was manufactured by MVM. It is a cost effective unit that really performs. Ask for Manhar: he is the owner and resident genius. He was always patient with my questions and requests.
