ABSTRACT:
A liquid crystal polarization reorientation cell includes Helmholtz coils disposed on either side of the cell to provide a magnetic field that is substantially perpendicular to the transparent members. The energizing of the magnetic field is utilized to selectively reorient the polarization of at least one frequency of an incident light beam.
