I'm trying to figure out a way to scan a 2D raster (like a TV or CRT monitor) with a beam using two rotating mirrors for the X and Y positions.
I'm looking for a shape that will, when spinning, deflect a beam in discrete steps on one axis only.
Combining two of these should let me scan a raster of theoretically very large size and a high speed.
I'm not sure this is the correct place for this kind of question as its more physics rather than math, but as they say, physics is just applied math right?
The problem i'm facing is that it seems that on a spinning disk any deflection would cause a 'wobble' or change the divergence of the beam (as it would be reflecting off a conical surface)
