WebOptical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity.Optical activity occurs only in chiral … WebJul 24, 2024 · Such spectral tuning has been achieved by electric-field-controlled birefringence effect in organic liquid crystals 5,6,7,8, and recently been extended to …
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 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 … 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 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. … See more 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 … See more WebThe atomic arrangement of the crystal itself is the source of birefringence. Examples are calcite, tourmaline, and many others While on the other hand, pressure-induced …
