WebBirefringent coatings carry a portion of the load that would otherwise be carried by the structure. Thus, strains at the structure-coating interface are somewhat less than those in an uncoated part. In addition, strain gradients through the coating thickness must be taken into account to determine the surface strains that would be developed in an uncoated … WebOct 20, 2016 · We characterize scattered light in polarization optics designed to maintain uniform illumination on target during spherical direct drive fusion experiments. An optical scatter instrument is used to measure the scatter distribution in the forward and backward hemispheres. Preliminary integrated scatter results from magnesium oxide birefringent ...
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 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 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 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 crystal structure (as determined by one of the 32 possible crystallographic point groups 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 WebAbstract. Utilizing the birefringent-coating technique complemented with data from electrical-resistance type of strain gages, the whole field stresses and stress-concentration factors were determined for single fillets and grooves for uniaxially and biaxially applied loads.
