WebMar 11, 2024 · 1.3 Faraday Effect. This is a very interesting (and often undesirable) behavior of some materials that we called birefringence. For example, let’s say that you have a piece of quartz and you look at a text behind it. Under certain conditions, it will be possible to see the same text twice, kind of like a ghost image of the original text. WebThe significance of the birefringence is that optical materials can be cut to impose specific changes in the polarization of incident beams. For example half-wave plates are cut to impose 180o (1 2 2! ()) phase shifts. When linearly polarized light travels in a birefringent crystal, the phase difference imposed on the two
WebFeb 20, 2024 · Birefringence is formally defined as the double refraction of light in a transparent, molecularly ordered material, manifested by orientation-dependent WebBirefringence is an intrinsic property of many optical materials, and may also be induced by external forces applied to the material. The induced birefringence may be temporary, as when the material is oscillated, or the birefringence may be residual, as may happen when, for example, the material undergoes thermal stress during production of ...
WebMay 6, 2013 · The analysis is therefore based on the different birefringent properties of the two film forming components, Θ (+) relates to the relative area of the sensor surface which is covered by lipid-like material, showing positive birefringence, while Θ (−) represents the area covered by polymer-like molecules showing negative birefringence. WebStress Measurement. Stress in optical materials commonly presents itself by generating an anisotropy in the material ( Stress-Induced birefringence ). Measuring the birefringence, material thickness, and knowing the material's stress optic coefficient, allows the calculation of the resulting differential stress in the material.
WebApr 22, 2024 · Recent progress on the molecular interpretation of strain-induced birefringence for amorphous polymers over a wide time/temperature region is briefly reviewed. In the rubbery region, orientational birefringence, which is caused by the orientation of segments, is dominant, while in the glassy region, glassy birefringence …
