ABSTRACT:
Apparatus for rotating polarization of polarized light includes an input of linearly polarized light, a variable retarder for retarding the phase of one quadrature component of such linearly polarized input light an amount relative to the phase of the other quadrature component, and an analyzer for converting such quadrature components to linearly polarized light having a plane of polarization that is a function of the amount of such phase retardation. By changing the electrical input to the retarder the amount of rotation can be altered.
