(under subclass 115) Subject matter wherein the multiple signals are distinguished from one another by the particular individual signal vibration perpendicular to the ray direction of travel.
(1) Note. The vibrations are straight lines, circles, or ellipses which produce, respectively, plane, circular or elliptical polarization.
(2) Note. The light waves are modulated by altering the polarization (relative to a reference) in accordance with the information signal.
