The internal structure of crystals (the specific structure of the crystal lattice, and the specific atoms or molecules of which it is composed) causes the speed of light in the material, and therefore the material's refractive index, to depend on both the light's direction of propagation and its polarization. The dependence on polarization causes birefringence, in which two perpendicular polarizations propagate at different speeds and refract at different angles in the crystal. This ca… WebMar 31, 2024 · To obtain one object plane that is perpendicular to the optical axis and its paraxial region, the following steps should be followed: Keep the measured object plane’s space attitude for the pitching and Z-axis position constant.
