Index ellipsoid
text:
In crystal optics, the index ellipsoid is a geometric construction which concisely represents the refractive indices and associated polarizations of light, as functions of the orientation of the wavefront, in a doubly-refractive crystal. When this ellipsoid is cut through its center by a plane parallel to the wavefront, the resulting intersection is an ellipse whose major and minor semiaxes have lengths equal to the two refractive indices for that orientation of the wavefront, and have the direc
