(under subclass 367) Subject matter including an electrically operated rotator of the polarization plane.
(1) Note. Where an electro-optical rotating means is used to vary the intensity of the light, rate of the pulsations of light, or change the plane of polarization of the light of an article or material being examined without indicating the change in the polarization of the light, search subclasses 366, 369, and 370.
