I wonder if the requirement to rotate the target is inherent, or if it could be optimized away eventually?

  Or rotate the telescopes

    ... which are radially symmetric.

      I recognize the ambiguity, but was referring to the orientation of the telescope system to the target.

  I suspect this was an easy way to test it without having to build a rotatable optical bench. A practical device may be an array of light sources and telescopes on a rotating mount or a set of moveable mirrors that achieve the same effect.

  If it is required, then in a real application you could just rotate the laser array instead.

  I also wonder about the requirement for the letters to be made of reflective material.
