Birefringence — Displacement of light rays with perpendicular polarization through a birefringent material … Wikipedia
birefringent — Any material that has different refractive index according to the plane of polarisation of the light. The effect is to rotate the plane of the refracted light so that, using crossed Nicholl prisms (polarisers set at right angles to give complete… … Dictionary of molecular biology

Photoelasticity — is an experimental method to determine stress distribution in a material. The method is mostly used in cases where mathematical methods become quite cumbersome. Unlike the analytical methods of stress determination, photoelasticity gives a fairly … Wikipedia
Polarization — ( Brit. polarisation) is a property of waves that describes the orientation of their oscillations. For transverse waves, it describes the orientation of the oscillations in the plane perpendicular to the wave s direction of travel. Longitudinal… … Wikipedia
brewster — (B) a unit used in optics to measure stress induced birefringence. A material exhibits birefringence if it has different indices of refraction along different axes. Many crystals exhibit birefringence. In addition, certain substances,… … Dictionary of units of measurement

Modern searches for Lorentz violation — Important motivations for modern searches for Lorentz violation are deviations from Lorentz invariance (and thus special relativity) predicted by some variations of quantum gravity, string theory, and some alternatives to general relativity.… … Wikipedia
double refraction — Optics. the separation of a ray of light into two unequally refracted, plane polarized rays of orthogonal polarizations, occurring in crystals in which the velocity of light rays is not the same in all directions. Also called birefringence. [1870 … Universalium
