Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive … See more A mathematical description of wave propagation in a birefringent medium is presented below. Following is a qualitative explanation of the phenomenon. Uniaxial materials The simplest type … See more While the best known source of birefringence is the entrance of light into an anisotropic crystal, it can result in otherwise See more Birefringence and other polarization-based optical effects (such as optical rotation and linear or circular dichroism) can be observed by … See more Birefringence is used in many optical devices. Liquid-crystal displays, the most common sort of flat-panel display, cause their pixels to … See more Much of the work involving polarization preceded the understanding of light as a transverse electromagnetic wave, and this has affected some terminology in use. Isotropic materials … See more The best characterized birefringent materials are crystals. Due to their specific crystal structures their refractive indices are well defined. Depending on the symmetry of a crystal structure (as determined by one of the 32 possible crystallographic point groups See more In an isotropic medium (including free space) the so-called electric displacement (D) is just proportional to the electric field (E) according to D = ɛE where the material's See more WebLight and Color - Optical Birefringence.

Birefringence Properties of Optical Materials (0.12 μm

WebBirefringence is an intrinsic property of many optical materials, and may also be induced by external forces applied to the material. The induced birefringence may be temporary, as when the material is oscillated, or the birefringence may be residual, as may happen when, for example, the material undergoes thermal stress during production of ... Webnoun. The resolution or splitting of a light wave into two unequally reflected or transmitted waves by an optically anisotropic medium such as calcite or quartz.

Constraints on axions from cosmic distance measurements

WebBirefringence is a measure of a gem's double refraction. It serves as one of the principal ways gemologists can identify gems. Natural zircon (not to be confused with cubic … WebJan 1, 2014 · Birefringence is a phenomenon to cause two refracted rays of light when a ray of light enters an optically anisotropic material. The two rays are, respectively, called the ordinary ray and the extraordinary ray, and their polarizations are orthogonal. Birefringence of polymer is often measured as difference between refractive indices for the ... Webdisk polarimetry [77] and CMB birefringence [78], which we do not show in the figure.
