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 WebJan 1, 2009 · A vector perturbation analysis which uses the 2D refractive index profile was developed to compute the optical fiber birefringence at any given fiber cross-section.

WebThe two-dimensional measurement principle for a birefringence vector distribution in transparent materials is analyzed. The system nonuniformity that results from the system components makes the two-dimensional measurement principle quite different from that of a point-measurement method, and the measurement principle requires a two-dimensional … WebBirefringence phase matching, described above, can suffer from certain limitations, including limited wavelength tuning range, smaller nonlinear coefficients, elevated phase-matching temperatures, awkward coupling angles, and the associated Poynting vector walk-off. An alternative approach, known as quasiphase matching, entails periodically … group rides johnson city tn

WebApr 13, 2024 · Coexistent linear birefringence was also analyzed using the same statistical processing of polarimetric images. In general, this anisotropic property is significant in all analyzed CNC-samples. At blue wavelength, Fig. 9a, linear birefringence of lower CNC-concentration films is almost independent of solvent-pH value. However, for 5%wt CNC ... WebMay 20, 2024 · The value of birefringence in chicken skin is estimated as 0.3 × 10 − 3, which agrees with alternative studies. ... While the polarimetric parameters on their own do not allow distinguishing the contributions of scattering and birefringence, the resultant Stokes vector trajectory on the Poincaré sphere reveals the role of scattering and ...
