Determination of the components of the gyration tensor of quartz by oblique incidence transmission two-modulator generalized ellipsometry

摘要

The two independent components of the gyration tensor of quartz, g_(11) and g_(33), have been spectroscopi-cally measured using a transmission two-modulator generalized ellipsometer. The method is used to determine the optical activity in crystals in directions other than the optic axis, where the linear birefringence is much larger than the optical activity.
