Birefringence can be caused by the crystalline structure of the material, a stress field either inherent in or applied to the material, application of an electric or magnetic field, etc. The properties of a device which is birefringent will be the same, regardless of the source of the birefringence.
WebMar 11, 2024 · Birefringence has several applications. It can be used to find defects in the manufacturing process, or identify weak spots in plastic structure manufactured via … Birefringence is used in many optical devices. Liquid-crystal displays, the most common sort of flat-panel display, cause their pixels to become lighter or darker through rotation of the polarization (circular birefringence) of linearly polarized light as viewed through a sheet polarizer at the screen's surface. … See more 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 … See more While the best known source of birefringence is the entrance of light into an anisotropic crystal, it can result in otherwise optically isotropic materials in a few ways: • Stress birefringence results when a normally isotropic … See more Birefringence and other polarization-based optical effects (such as optical rotation and linear or circular dichroism) can be observed by measuring any change in the polarization of light passing through the material. These measurements are known as See more A mathematical description of wave propagation in a birefringent medium is presented below. Following is a qualitative explanation of the … 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 have symmetry in all directions and the refractive index is the same for any … 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 permittivity ε is just a scalar (and equal to n ε0 where n is the index of refraction). … See more
