Abstract:
A polarization modulator includes a first liquid crystal cell and a second liquid crystal cell. The first liquid crystal cell has a first type of liquid crystals configured to rotate an optical axis of light parallel to a first plane of the first liquid crystal cell. The second liquid crystal cell is configured to receive the light from the first liquid crystal cell. The second liquid crystal cell has a second type of liquid crystals configured to rotate the optical axis of the light perpendicular to a second plane of the second liquid crystal cell.
