WebJan 1, 2008 · We develop a spectral-domain polarization sensitive system, which can get birefringence and Stokes vector of the samples with scanning rate of 260 Hz and depth … WebBirefringence can occur only in optically non-isotropic materials. Often, it results from non-cubic lattice structures of optical crystals, i.e., an intrinsic anisotropy.. In other cases, birefringence can be induced in originally … highway from east coast to west coast
Birefringence vector computation and measurement for …
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 … 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 … See more Much of the work involving polarization preceded the understanding of light as a transverse electromagnetic wave, and this has affected some … 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 … 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 … See more WebApr 10, 1999 · The two-dimensional measurement principle for a birefringence vector distribution in transparent materials is analyzed.
