The machine which I have suggested has no teeth or holes, but a 
reflective rim along the surface of two wheels.

Into the surfaces there are very fine stripes etched (or burned in by a 
laser or printed). The grid is 'read' by a laser, that operates somehow 
similar to the pick-up of a blue-ray or DVD disk reader. The laser is 
focused to a dot of sufficiently small size (in the range of microns).

This setup is significantly different to those experiments you have 
mentioned and therefore does not suffer from the problems you had in mind.
