Measuring Scan Angle....

[allthatwhichis]

Yes, However I plan on writing a review on my new galvos and want to provide data on the scan angle at different speeds. I plan on running them at 30K but I want to see what it can do accurately at 20K, 40K and 50K.
Thanks!

I got ya. I thought you were just tuning for use.

That pattern is all about driving your scanners to their absolute max with a minimal set of coordinates (to make the circle). It relies heavily on the fact that scanners have mass and can be driven to a real limit of accurate swing between reasonable coordinates in both axis. That accuracy will ultimately fall off at a predictable rate, after that frequency limit is breached.

That's all cool! But my question is, how does that translate into a reasonable quantified value like "radians per second"?

That question is covered rather well in this old thread. Pay particular attention to Bill Benner's reply regarding small signal bandwidth. It cleared up a *lot* of questions I had about scanners. There's a ton of good info in that thread.
