galvo scanner ans rotating off-axis mirror for beam offseting?

[shoujin]

I don't really have a 3d optical ray tracing program or experience to measure this.
Can anyone tell me if such a setup will give the results I assume:



Assuming the off-axis mirror can be attached to a rotating mount, can the beam shooting at any point on it from the scanner be made parallel to the middle beam bounced off of the off-axis mirror?

... the emitted beams won't be parallel - draw them with the angular displacement from the galvo head (more correct, when starting with the first galvo), so you'll see the emitted "cone".

To make it parallel, you'll need a cavity with the exact radius distance -- this is not doable with off-axis rotation ...

How about a non rotating off-axis parabolic mirror? I was trying to avoid this method to not introduce distortions from converging of the beam because of the parabolic shape...
