Web1 day ago · Birefringence can be affected by a number of factors such as bond orientation [79] strain [80], and polarizability [81]. The inversion of the birefringence was intimately related to the smaller Mn-O bond length in comparison to Zn-O along the c direction [82] i.e. smaller dipole moment (p → = l → q). A smaller bond length in the [0001 ...
WebApplications of birefringence . Birefringence is widely used in optical devices, such as liquid crystal displays, light modulators, color filters, wave plates, optical axis gratings, etc. It also plays an important role in second harmonic generation and many other nonlinear processes. It is also utilized in medical diagnostics: needle ... WebBirefringence is the phenomenon exhibited by certain materials in which an incident ray of light is split into two rays, called an ordinary ray and an extraordinary ray, which are plane- (linear) polarized in mutually orthogonal planes, or circular-polarized in opposite directions (left and right). From: Lasers for Medical Applications, 2013.
Webpair of elliptical polarization states. 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. WebFor example, solutions containing long-chain molecules exhibit double refraction when they flow; this phenomenon is called streaming birefringence. Plastic materials built up from …

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.
