DEFINITION

Classification: 359/192

With polarization:

(under subclass 191) Subject matter wherein the heterodyne optical demodulating receiver is used to detect a light wave having vibrations perpendicular to the direction of travel of the light beam.

(1) Note. These vibrations are in straight lines (plane polarization), circles (circular polarization), or ellipses (elliptical polarization).
