ABSTRACT:
Certain exemplary embodiments comprise a method that can comprise, responsive to an instruction to change a setting of a polarization controller, automatically changing a first rotational speed of a birefringent plate associated with the polarization controller to orient the birefringent plate pseudo-randomly over time with respect to a predetermined axis.
