Sorry for the double post!
I had a second look at the sensor I linked, and it was not the right type of sensor! The one above is a simple on/off sensor design to replace reed switches in low power applications.
What I meant to link was something like this:

This device has angle resolution less than 0.05deg over 90 degrees operating range. However it does have a hysteresis error of 0.017deg (but over the entire range that is less than .02%).
Something like this could be easily used to implement an analog PID positional controller to ensure accuracy in the galvos and dampen the drive.
