Polarization control device |
摘要 |
A polarization control device, comprising: a liquid crystal device containing a liquid crystal material with an optical anisostropy with substantially homeotropically aligned molecules when in a neutral electrical field state; a plurality of electrodes for applying an electrical field to change an orientation of the molecules of the liquid crystal material from their alignment in the neutral electrical filed state; a circuit for applying a voltage to the electrodes; and an optical system for directing light through the liquid crystal material.
