elliptical polarization
elliptical polarization In optical mineralogy, light passing through a mineral may be split into two rays. The velocity of one ray is uniform in all directions, to give a spherical wavefront; the other ray varies in velocity with direction, to give an ellipsoidal wavefront. Elliptical sections so produced are used to determine the optical properties of minerals.
