A new photoelectric method of determining the azimuth of polarized light has been devised. For measuring the relative retardation of birefringent crystals, Sénarmont compensator is being used. When this compensator, made up with a polarizer, a quarter-wave plate and an ADP Z-cut crystal, is subjected to a field of alternating voltage, the plane of polarization of light emerging from the compensator vibrates in accord with the applied voltage. This optical system is named “polarization azimuth vibrator” which is useful in determining the azimuth of linearly polarized light. Application of this element to polarimetry is reported.
