If the laser is "statically scanned" such as with a line generating lens
as Dan is doing, then the failure mode of the scanning motor is
eliminated.  The downside is that the beam intensity at any one point is
not full power, but the upside is that it there for a long time and
there would be no beat with the camera scan frequency.
