In any case I think that moving a mirror at a constant rotation speed (sweep mode) should be easier than moving it under the "random" requirements of a vectorized system.

A vectorized system needs to speed up and slow down the mirror very fast, in order to move fast from one point to another. And the mirror mass, plus all the moving mechanics, present an important inertia effect.

On the other hand, the sweep mode needs much more peak lighting power because the power is applied for each 'pixel' only for a little time fraction compared to the whole scanning cycle.
