    hate to burst your bubble but If I had a 10$ bill for every time I'd seen the word microvision in the past 8 years I'd own pangolin pro and my own house of ill repute in vegas by now. They make great prototypes, for things like direct retinal scanners etc and thats as far as it seems to get.

    Has anyone thought about trying to tackle an X and Y galvo that is a single unit (like the one show)? I imagine it could be done with capacitive feedback. The moving mass intertia would HAVE to be less that two rotors.

    I think those are resonant scanners, so pretty much useless for laser show use

    I don't see how those could be resonant. That would mean that each axis would be scanning at the exact same frequeny which wouldn't work considering that the image is a 4:3 image not to mention that X axis sweeps across why the Y axis step down for an NTSC format. Maybe I'm wrong, but... I still think that you could conceivably use that type of XY axis frame to drive a single mirror. Sure, the drive unit may not be that small, but the mass would be low and the inertia would have to be lower than regular single axis galvos.
