Ok, the cure time per spot is a LOT faster than I was thinking! I can see why galvos would be preferred.
I came across this page which looks pretty interesting [elm-chan.org]. He is using 12 bit DAC (4096 points), I am not sure what effective resolution he gets from the overall system. He's got a lot of bespoke electronics in there.
" It will not needed to explain each function of the controller board and its firmware because you must have a skill to design a laser display controller if you are going to build galvos."
:)
Do you have any off the shelf galvos in mind? It would be useful to get some specs to see what is needed to drive them. I found this on ebay, [www.ebay.co.uk] it is just about within my budget for "playing around with".
