WebThe optical indicatrix gives the relation between the direction of vibration and the index of refraction of light propagating in the crystal. In this paper, from the direction of the wave normal and So far, we have assumed that refraction is given by linear equations involving a spatially constant, scalar refractive index. These assumptions can break down in different ways, to be described in the following subsections. In some materials, the refractive index depends on the polarization and propagation direction of the light. This is called birefringence or optical anisotropy. the hood in austin
