Say Bill...
I know this is taking up even more of your time, but I'm really curious about this audience scanning system you've gotten approved. Would you mind talking a bit about a few specifics of the projector itself? I'm curious as to how large you ended up expanding the beam to, and where in the optical path you did so. (ie: before or after the galvos) Also, how much power are you running?
That is, if you are free to discuss the details of the system at this time...
